Our FAQ section provides answers to many of our most common questions.

  • Wheels & Rims

    What makes Stan’s NoTubes rims special?

    The most unique thing about our rim designs is the shape. They feature a shallow drop-channel, a smooth transition, a wide, flat bead seat, and a very low sidewall. These features together make up our Bead Socket Technology (BST) and give a very secure fit with virtually any mountain bike tire. Our rims are also incredibly lightweight for their categories, making the wheels feel very quick by lowering the rotational mass.

    Why doesn't Stan's NoTubes offer an asymmetrical or offset rim?

    While it is true that an asymmetrical or offset rim can allow for better triangulation of spoke angles and balance of tensions in some wheel builds, the trade-off for us would be the necessary modification of our internal BST rim shape and a compromise of our tubeless performance.

    What do I need to run my Stan’s wheels tubeless?

    For our mountain bike wheels, you will need one layer of our yellow tubeless tape (width varies by model), a universal valve, and sealant. Our road rims require two layers of tape. All of our in-house built wheels come with tape and valve stems pre-installed.

    What tires can I use?

    With proper tubeless setup, most mountain bike tires can be used on our rims without inner tubes, but we recommend choosing tires labeled "Tubeless Ready" for best results. Some tires are more porous than others, and may require more sealant during initial setup. Road tires, or any tire designed to be inflated over 45psi, must be specifically labeled for tubeless use. Only specially reinforced tires specifically labeled as "road tubeless" are designed to handle pressures above 45psi. When in doubt, consult the manufacturer of your tire. Road tires that are labeled, “Use only with hook bead rims” should never be used tubeless.

    Can I use tubes in my Stan’s NoTubes wheels?

    Yes, absolutely. We believe that tubeless is the best option for all riding applications, but tubes can be used in the event of an emergency.

    What is the weight limit on Stan’s wheels?

    Our weight limits are determined by the individual components of the wheel build (spoke gauge, lacing pattern, hole count, rim choice) and vary between wheels. Please check the individual wheel page for a weight guideline for the wheel of your choice. Weight limits are flexible based upon intended use and rider skill level.

    What is the maximum tire pressure I can use?

    Maximum tire pressure is specific to the rim and width of the tire you will be riding. Maximum tire pressure for common tire sizes is listed on each of our rims. If you are unable to locate this information on your rims, please feel free to contact us. Maximum pressures are the same for both tubed and tubeless applications.

    Should I buy the Grail or Iron Cross Wheelset?

    That depends on how you’d like the ride. The Iron Cross is designed as a cyclocross-specific wheelset. That means it is only rated for low-pressure (under 45psi) use, like our mountain bike wheels. If you would like to ride road tires, or even gravel tires and run more than 45psi, the Grail is the right choice for you.

    Why is my cassette digging into my freehub body?

    Stan's freehubs are made lightweight using aluminum like many other brands. We recommend using cassettes with a rigid alloy carrier (XTR, XT, XO, etc. - Figure 1) for the largest sprockets. Cassettes with individual cogs (Figure 2) may mark the alloy freehub, though marks are only cosmetic and will not affect the performance of the hub.

  • Road Tubeless

    What is the benefit of Road tubeless?

    Road tubeless offers the same benefits as tubeless mountain bike applications: Less flats, lower rolling resistance, more comfort, and more traction. All while being lighter than a traditional tube-type setup.

    Can I convert any road wheel to tubeless?

    It is our experience that most 700c road rims can be converted with our road tubeless bundle. Deep section rims may require a valve extender. Please check with the manufacturer of your rim for their recommendations on tubeless use.

    Can I convert any road tire to tubeless?

    No, road tubeless tires must be specifically labeled for tubeless use. Most manufacturers produce a road tubeless tire. Road tubeless requires a special bead to maintain a secure fit with the rim.

    What pressure should I run in my tubeless road tires?

    Rider weight and terrain will ultimately help you determine your preferred pressure; a good starting point is 10% lower than you would run with tubes.

    Do I need to use rim tape on sealed rims like the Mavic Ksyrium?

    Tape is not necessary to seal the rim, but we recommend adding one layer to protect un-anodized or scratched areas of the rim from oxidation due to moisture in the sealant.

  • Sealant

    Can I run your sealant in other brands of tubeless rims?

    Yes, our sealant can be used in any tubeless application, including UST. Please follow your rim manufacturers guidelines regarding the use of sealant.

    How much sealant should I use?

    For a XC 29er tire we recommend 3-4 ounces (89-118ml) of sealant. The amount of sealant can be adjusted based on the volume of the tire. More sealant can also be added if a tire is porous and difficult to seal. For road and cyclocross tires, we recommend 2 ounces (60ml).

    Can I add sealant to my tubes or tubular tires?

    Yes, if the tube or tubular has a removable valve core. If there are two opposing flat surfaces just below the top of the valve, you can use our valve tool link or a small set of needlenose pliers to unthread the core and sealant can be installed. We recommend injecting 1-2 ounces (30-60ml) of sealant into tubes or tubular tires. Sealant will not damage tubular tires.

    Why is my tire weeping/leaking sealant?

    This is the natural process of the sealant evaporating. It is more evident in some tires, but is nothing to be overly concerned about. This “weeping” does not impact the effectiveness of the sealant. The weeping will dissipate as the sealant seals the casing of the tire. More porous tires may require a sealant refresh shortly after the initial setup.

    How long will the sealant last in my tire?

    The sealant should last anywhere from 2-6 months or longer. However, there are many factors that the time will depend on: temperatures in your area, weather and humidity conditions, how often you ride, where you store your bike (cooler is better), tire casing thickness, number of punctures the sealant has already sealed that you never knew you had, etc.

    What is the sealant shelf-life?

    Sealant bottles should be kept tightly sealed, and stored in a cool, dry place. The sealant can be expected to last for many years if not used.

    Will Stan’s sealant freeze, at what temperature?

    Anti-freeze agents allow the sealant to be used in environments as cold as -20°F (-28.8°C)

    I heard there is ammonia in your sealant and it is bad for my tire and or rim?

    Any trace amount of ammonia in Stan’s sealant will evaporate soon after it is injected into the tire. We have found no damaging effects from our sealant even after years of use. Although tape may not be necessary to seal your rim, you may add one layer to protect un-anodized or scratched areas of your rim from oxidation due to moisture in the sealant.

    Will using your sealant void the warranty on my tire?

    Using our sealant may void the tire warranty with certain manufacturers. Stan’s NoTubes sealant will not damage your tire. Please consult your tire manufacturer’s warranty guidelines.

    How do I get your sealant out of my tires or tubes?

    Liquid sealant can be rinsed out with water or wiped away with a rag. Stan’s sealant is biodegradable. It is not necessary to remove dried sealant from your tire, but large areas can be peeled away by hand or scrubbed away with a stiff brush.

    How do I get sealant out of my clothes?

    Rinse any spills with cold water as soon as possible; do not let the sealant dry. We also recommend using a surfactant-based detergent such as Tide. Unfortunately, once your clothing is stained, it will most likely not come out.

    What is Race sealant?

    Race sealant is very similar to our standard sealant, but designed for racing applications. The sealant contains both a greater amount as well as larger particles of our proprietary crystals. This increase allows for the sealant to seal larger punctures and keep you racing. Race sealant is made for race-day use and needs to be inspected more often than standard sealant, approximately every 3-4 weeks. Race sealant also cannot be injected through the valve; you must break the bead and pour the sealant directly into the tire.

    Can I mix Race sealant with your standard sealant?

    Yes, our two sealant formulas can be mixed.

    Do I need to clean the sealant out of my tires?

    It is always good to wipe excess sealant out of your tires if you plan to use them again. A dry rag is sufficient for cleaning out regular sealant. Race sealant must be rinsed out of the tire with water after use and then wiped with a rag. Excess Race sealant will dry, causing the casing to stiffen and make re-installation difficult.

  • Tape

    Which width tape should I use?

    The widths of our tape are selected with our rims in mind. Generally, we recommend tape that is 1-2mm wider than the internal width of your rim to account for the drop channel.

    Can I convert my standard mountain bike rim to tubeless with tape and valve only?

    While it can sometimes work, we do not recommend it. Without our molded rim strips, your tires will not have a secure fit with the rim and can burp air or even come off the rim. The rubber rim strip reshapes the interior of your rim, creating a shape similar to that of our rims. This creates a BST-like fit that ensures a secure, leak-free fit.

    Can I use Gorilla tape?

    We do not recommend the use of Gorilla or similar tapes in our rims. That type of tape is porous and too thick to be used with our rims.

    How many layers of tape should I use?

    That depends on the rim and application. BST wheels are designed for low-pressure use (under 45psi) and require one layer of tape. BSTr wheels are designed to withstand high-pressure use (over 45psi) and require two layers of tape.

    Why isn't my tape sticking?

    Our tape is designed not to leave residue on the rim surface and therefore does not have excessive adhesive. Make sure the rim is very clean before applying. We recommend spraying with isopropyl alcohol and wiping with a clean rag. Pull firmly while applying pressure with your opposite hand to hold the tape in place. Do not attempt to re-use tape once it has been removed from the rim.

    How do I install the tape?

    Tape should be applied evenly without air bubbles or going up the sidewall. View the video here.

    Can I patch my tape?

    We do not recommend patching or partially repairing your rim tape. If your tape has been damaged, peel off all of the tape and re-tape the rim.

  • Tubeless Conversions

    What is burping?

    Burping is a term we coined very early on in the tubeless revolution to describe the rapid air loss that occurs when the tire bead becomes separated from the rim while riding. Our BST rim design and use of our conversion rim strips eliminate burping.

    Why do I need a rim strip?

    Our molded rim strips reshape the interior surface of your rim to mimic that of our rims. This reshaping creates a much more secure BST-like fit between the tire and the rim, allowing for easier inflation/setup and eliminating burping. Please follow manufacturer's recommendations for setup of tubeless-ready wheels.

    Which conversion kit or rim strip do I need for my rim?

    Check out our rim strip and conversion kit page to determine the proper rim strip or kit to purchase. If you do not see your rim listed on the page, follow the guidelines for measuring your rims. We do not currently offer any conversion kits for fat bike rims.

    Can I convert my standard mountain bike rim to tubeless with tape and valve only?

    While it can sometimes work, we do not recommend it. Without our molded rim strips, your tires will not have a secure fit with the rim and can burp air or even come off the rim. The rubber rim strip reshapes the interior of your rim, creating a shape similar to that of our rims. This creates a BST-like fit that ensures a secure, leak-free fit.

    How can I easily add sealant to my UST wheelset?

    If your valves feature a removable core, you can sealant directly through the valve using our sealant injector. We also offer Universal Valve Stems that feature a removable core and will work with your UST rim and allow you to add sealant without breaking the bead. If you using race sealant, you must add sealant to your tire before fully installing it on the rim. Race sealant contrains too many sealing crystals and will clog the valve core if.

    I have UST rims and want to use standard tube-type tires, what do I do?

    Tube-type tires fit loosely on UST rims. We recommend installing one of our rim strips for this combination. Rim strips reshape the interior of your rim, creating a much more secure fit with the tire. Sealant is necessary to make the casing of tube-type tires airtight.

  • Tires

    What tires can I use on my NoTubes rims?

    Low-presssure (up to 40psi): One of the biggest benefits of the Stan’s NoTubes tubeless system is its versatility, and the shape of our BST rims enables the use of just about any tire, be it standard bead, “tubeless-ready”, or UST.

    High-Pressure (above 40psi): All tubeless set-ups above 40psi must use a tire specifically labeled for tubeless use. Our BST-R rims are designed to accommodate these tires and pressures.

  • Fat Bikes

    Can I convert my fat bike to tubeless?

    Yes, tubeless is a great option for fat and plus bike riders. We do not offer any conversion products specifically for fat bikes, but our sealant works great in cold temperatures down to -20°F (-28.8°C).

    Does Stan’s have fat bike tape or rim strips?

    We do not currently offer an fat bike-specific tubeless products or kits.

    How much sealant should I use in my fat bike?

    We recommend starting with 6-7oz (177-207ml) per tire. More sealant may be required for particularly porous tires. Sealant will have the same life inside your fat bike tire of 2-7 months that it does in standard mountain bike tires.

  • Custom Wheelsets

    Our custom wheelset builder can be found here.

    How long will it take you to build my wheelset?

    3 to 10 business days.

    I’m building a set of Stan’s wheels. What spoke lengths do I need?

    There are several things you need to know to determine the optimal spoke length for your wheel build, including the effective rim diameter (ERD), lacing pattern (3-cross, 2-cross, radial, etc.) and which hub you are planning to use. Each rim web page and rim sticker lists the ERD. Once you have collected all of the necessary information, use one of the free online spoke calculators to determine the proper length spokes for your build. The spoke length calculator we use is available here: Neo Hub and 3.30 Hub.

    Do you offer wheel builds with other manufacturer's hubs?

    No, we only offer our wheels built with Stan’s NoTubes Neo hubs.

    Can I send you hubs for a custom wheel build?

    Sorry, we do not accept outside hubs for custom wheel builds.

    Can I buy rims, spokes and hubs from Stan’s to assemble myself?

    Sorry, we do not sell the individual wheelset components. We only have complete wheels, or rim-only available for purchase.

    Do you offer different color decals?

    Yes, we do! We offer seven different colors in our custom wheel program. Replacement/aftermarket decals are also available for purchase here.

    Do you offer different colored nipples?

    Yes, our custom wheels can be built with the color nipples of your choice.

  • Wheel Building

    What does Stan's build tension mean?

    Each Stan's wheel is built to a specific tension for the rim used. For each of our rim models, we have found a tension that provides the best ride quality possible. Please note this tension is measured without a mounted tire on the rim. As is the case with all wheels, tension will lower noticeably once a tire is installed.

    Please see the Wheel Setup Guides link in the Help Center for specific build information for your wheels.

    Where are your wheels built?

    Most of our aftermarket wheels are machine laced and finished by hand in our Big Flats, NY facility. Some international distributors utilize our Taiwan based wheel building facility where all wheels are built entirely by hand but follow the same quality control procedures as in NY. Certain distributors also build wheels by hand following a match spec to our other aftermarket offerings.

  • 3.30 Hubs

    Can I put an XD driver on my CX wheels?

    If your wheels are built with a 3.30RD hub, they are designed for road gearing options only and are not compatible with an XD driver.

    Can I use 11-speed road parts with my mountain wheels?

    Standard 3.30 hubs are 8/9/10 speed only and are not compatible with 11-speed road components. The 3.30RD hub is 11-speed compatible. The new Shimano 11-speed mountain cassettes (XTR, XT) fit on a standard 10-speed freehub body (and require the use of a cassette spacer on 11-speed road freehubs).

    Can I convert my singlespeed hub to 12x142?

    That depends on which hub-version you have. If both end caps are press-fit, yes your hub can be converted. If your end caps thread onto the hub, your hub cannot be converted to 12x142.

    Can I use my singlespeed hub on my geared bike?

    No, the singlespeed hub is only designed for singlespeed use and will not accept a freehub for geared use. If you would like to use you wheels on both geared and singlespeed bikes, we recommend using a standard Shimano freehub body, and a cog spacer kit for singlespeed use.

    Can I convert my 3.30 hub to Boost spacing?

    No, you cannot convert to Boost spacing. Boost spacing requires a wider hub shell to align the rotor and freehub body; it is not simply an endcap conversion. The 3.30 hub is not available in Boost spacing. Please browse our wheels with Neo hubs for Boost compatibility.

    Are 3.30 and Neo hubs part interchangeable?

    No, the release of our Neo hub was a complete departure from our 3.30 series and does not share any of the same parts. Only 3.30 replacement parts can be used with our 3.30 hubs.

  • Neo Hubs

    What end caps come with my wheels?

    Wheels will ship with 15x100mm front and 12x142mm rear end caps installed. Quick release end caps are supplied in the box as well. Boost options do not come with extra end caps.

    Are the wheels 11-speed compatible?

    Yes, Neo hubs come standard with an 11-speed freehub body and can be used for all 8, 9, 10 and 11-speed applications. SRAM 11-speed mountain gearing requires the use of an XD driver. The included 1.8mm spacer is always required except when using an 11-speed road cassette.

    Can I use my singlespeed hub on my geared bike?

    No, the singlespeed hub is only designed for singlespeed use and will not accept a freehub for geared use. If you would like to use you wheels on both geared and singlespeed bikes, we recommend using a standard Shimano freehub body and a cog spacer kit for singlespeed use.

    Can I convert to Boost spacing?

    No, you cannot convert to Boost spacing. Boost spacing requires a wider hub shell to align the rotor and freehub body; it is not simply an endcap conversion. The same applies when attempting to convert from Boost to conventional spacing. Neo hubs are available in Boost spacing for all of our wheel models.

    Are Neo and 3.30 hub parts interchangeable?

    No, the release of our Neo hub was a complete departure from our 3.30 series and does share any of the same parts. Only Neo replacement parts can be used with our Neo hub

    Why does my Neo Lefty hub have play?

    Due to the tight tolerances inherent in the Lefty design, a small number of Lefty hubs can exhibit signs of lateral play at the spindle during setup or after initial use. An additional shim can customize the fit and eliminate play at the hub. Click here for shim installation instructions.

  • MK3 Wheels

    What is the difference between the Crest and Crest MK3? The Arch Ex and Arch MK3? The Flow and Flow MK3?

    All of our MK3 rims have been redesigned based on years of success with previous generations of our wheels. All of the rims receive a new low-profile shape, an improved alloy, became wider, 25% stiffer, and in some cases also became lighter. However, the MK3 rims still share the same patented rim architecture and tubeless performance as previous generations of our rims.

    The Crest MK3 is 2mm wider than the previous generations and with the help of a new alloy is also 16g lighter.

    The Arch MK3 went through the most significant change, becoming 5mm wider internally compared to the Arch EX. Though the rim is radically wider than the previous generation, the new rim shape and alloy allows the rim to keep the same weight as the previous Arch EX.

    The Flow MK3 also got a bit wider, jumping up to 29mm, compared to the 25.5mm internal width of the Flow EX. Our new profile and alloy also helped the Flow lose a bit of weight, dropping and average of 5% of rim weight across the size range.

    What tape does the MK3 use?

    Crest MK3 - 25mm
    Arch MK3 - 27mm
    Flow MK3 - 30mm

    What valve does the MK3 use?

    The MK3 uses the 35mm universal valve

    Can I use the same spokes if I want to rebuild on a MK3?

    Check out the Stan’s NoTubes rim chart to verify that the ERD of your chosen MK3 rim matches that of your existing rim. Rims with ERD’s within +/-1mm can use the same spoke length. However, we do not recommend reusing spokes as the previously stretched and fatigued spokes may compromise the strength and compliance of the wheel.

    Do you make MK3 in any color beside black?

    We only make black. There is a company called Project 321 that does sell our rims in custom colors. Click here for more information.

    To what max pressure can I inflate my tires to on a MK3? Does using a tube make a difference?

    Maximum tire pressure for all MK3 wheelsets is 45psi. Recommended max pressures are the same for both tubed and tubeless applications.

    What size tire fits on a MK3?

    Our WideRight system makes it easy to find the perfect rim width for the tire size and volume you ride. Too narrow of an internal rim mixed with a high sidewall design gives you a "light bulb" tire profile while an ultra wide rim on a narrower tire will give you a flat to "bell shaped" tire profile.
    Crest MK3: 2.00" - 2.25"
    Arch MK3: 2.25" - 2.50"
    Flow MK3: 2.35" - 2.80"

    Why didn’t you make the MK3 wider?

    Rims that are too wide can distort the tire profile, decreasing traction and control and driving impacts directly into the rim, negating the impact absorbing advantages of a tire's volume. Our WideRight rim widths are designed to strike the perfect balance between tire volume and sidewall function.

    What is the weight limit for MK3 rims?

    Our rims do not have a weight limit. Weight limits come from the combination of the rim, hub and spoke used for the different builds.

    Do you offer different color decals?

    Yes, we do! We offer seven different colors in our custom wheel program. Replacement/aftermarket decals are also available for purchase here.

  • S1 Wheels

    What are S1 wheels and how do they differ from the Mk3 models?

    The S1 wheel line is all new for 2017. These wheels are built around the same versatile Neo-series hubs as our MK3 wheels but use a heavier gauge spoke and brass nipples. The rims feature the same WideRight BST profiles as their MK3 counterparts but are extruded from less exotic 6061 aluminum and are sleeved rather than welded. S1 wheels are on average around 165grams/pr heavier than MK3 wheels.

    Why is there no “Add to Cart” button on the S1 product pages?

    Unlike our MK3 wheels which are built and ship from NY facility, S1 wheels are built to our specifications by a select group of our distributors and available exclusively through your local bicycle retailer.

    Can I buy S1 rims by themselves?

    No, S1 rims are offered only as part of a complete wheel.

    Which S1 wheelset is right for me?

    Our WideRight system makes it easy to find the perfect rim width for the tire size and volume you ride. Too narrow of an internal rim mixed with a high sidewall design gives you a "light bulb" tire profile while an ultra wide rim on a narrower tire will give you a flat to "bell shaped" tire profile. There are six different S1 profiles available to fit tires from 2” to 3”+ wide.
