A sophisticated solution: the Shimano Road conversion bottom bracket from Praxis Works


Praxis Works offers a solution for installing Shimano cranks (24 mm axle, Hollowtech II) onto BB30, PF30 and Specialized OSBB frames. The patented system is a complete and high-quality bottom bracket which guarantees a secure and perfect fit. It dispenses with wobbly or imprecise spacers and adapters that can cause cracking noises or premature wear on the bearing. This is why many well-known wheel manufacturers rely on these bottom brackets.

Technology:


Conversion BB
Conversion bottom brackets from Praxis Works are the leading bottom bracket solution for all Shimano, Campagnolo Ultra Torque or SRAM GXP cranks. They fit BB30, PF30 or Specialized OSBB frames. Patented Praxis Works technology not only neutralizes all tolerances from frame manufacturers, but also guarantees an increased service life. In Praxis Collet bottom brackets, the non-drive side is pressed in and then the drive side is screwed into it. When screwed together, the bearing expands to a defined end position, which corresponds to the respective press fit, and sits tight without creaking. Additionally, an orange elastomer rubber ring is compressed in the drive direction, which in turn expands towards the frame, thereby jamming the bearing once again. The elastomer material compensates for tolerances while simultaneously muffling any cracking noises.
