Water Repellent To make our BB86 Bottom Bracket even more durable, we've used special seals, which keep moisture out while keeping drag to a minimum. A tube is also included to further enhance water repellence. Our bottom brackets are hand-assembled, so we can ensure that all our BBs are finished to perfection to keep your bike riding smoother for longer. Ceramic Bearings With our ceramic bearing option, friction is reduced meaning less energy is required to turn the cranks, they're also more durable, and don’t rust so they'll require less maintenance. If you're a rider seeking out every possible advantage over the competition, the ceramic option can help take your performance to the next level.
Our bearings are highly polished so they spin smoother for longer, while the seals protect the bearings and races from dirt and debris that try to make their way in.
Creak-Free Bottom Bracket The bearings are held in place by an alloy cup, but in order to keep the BB and frame quiet and creak-free, they are housed in a plastic/nylon shell. Finding the right mix of plastic and nylon has allowed us to precisely manufacture these BBs so they won’t deform over time or when they get wet. It also allows the BB to fit in frames that aren’t perfectly aligned. Our bearings inside our BB386 BBs are precisely manufactured to spin smoothly, and when combined with our special seals, repel the elements. The seal is made from a mix of rubber and alloy to provide double protection for the bearings. And, we hand assemble these bottom brackets to ensure none of this development and precision is wasted.

The Praxis Works SRAM bottom bracket converter GXP/ISIS 2 is designed to be a proper bottom bracket BB for installing SRAM GXP/ISIS2 cranks in either BB30, PF30, or Specialized s OSBB road frames.Patent Pending Outboard Bearing Design Collet style non-drive cup expansion for wiggle-free pressNon-Drive O-Ring compensates for frame width discrepanciesFor BB30, PF30, and Specialized Road OSBB frames onlyFor SRAM GXP/ISIS2 cranksThe Praxis patent pending design keeps the cartridge bearings outboard of the frame right on SRAM spec for greater rigidity and free of frame/c-clip tolerance issues that other conversion bb systems deal with.Simply press in the longer non-drive-cup, then the shorter drive cup threads into it. As the drive cup threads in, the Praxis trademark Collet system expands to a precise limit evenly dispersing pressure for a super tight fit. With both cups connected and the collet set exactly to spec, there is no chance the bearings can come out of alignment or wiggle/walk out of the frame. This design also uses a compressible o-ring on the non-drive side cup to compensate for frame shell width discrepancies.
