BST-R

Stan's NoTubes BST-R Series


BST-R Logo BST-R Tubeless Technology for Higher Pressures

Our BST-R rim shapes are designed for maximum versatility, and can be used with a wide range of tires. Higher volume tires 32mm to 50mm wide can be used at pressures up to 45psi (3.1 bar). The BST-R rim shape can also be used with 25mm to 32mm road tires specifically designated as "tubeless" at pressures up to 115psi (7.9 bar). BST-R rims can also be used with tubes, at pressures up to 115psi.

The patented design of our BST-R rims secures the tire's bead, creating an air tight seal that lets the tire expand to its full volume. The result is more traction and less rolling resistance for increased speed.

Key Differences Between BST and BST-R

Our BST system was developed specifically for tubeless use with pressures below 45psi. From our Iron Cross to our Hugo, we offer low pressure BST rims for tires in the 32mm to 122mm width range. The broader pressure range of our BST-R Series rims and wheelsets means they're optimized for tubeless use with tires in the 32mm to 50mm range at pressures of 45psi or lower, as well as 25mm to 32mm tires specifically designated as "tubeless" that feature reinforced beads designed for pressures up to 115psi. Both BST and BST-R rims and wheelsets may be used with tubes.
