When a Praxis M30 bottom bracket starts to feel rough, the cups don't need replacing: this kit supplies the two bearings to rebuild it, in steel or ceramic.

Highlights

  • The M30-specific 30mm drive and 28mm non-drive cartridge bearings
  • Steel, or ceramic rated Grade 5 / ABEC 5
  • Fits Praxis M30 BSA, BB30/PF30, 386EVO, BBright and T47 external, internal and asymmetric BBs
  • Not for the M30 BB86/90/92 (PF41), which Praxis says can't be rebuilt

The right tools matter

Praxis requires proper bearing removal and press tools to swap these bearings, such as Enduro's bearing tool kit or a similar shop-level set. The wrong tools can damage the new bearings or the BB and void the warranty. If you don't have them, the Tune Cycles workshop can rebuild the BB as a separate workshop service.

Compatibility & fit

Only for Praxis M30 (30/28mm) bottom brackets: the BSA, BB30/PF30, 386EVO, BBright, T47 external, T47 internal and T47 asymmetric versions. Not for the M30 BB86/90/92 (PF41) version, and not for Praxis M30 THRU (30/30mm), M24/GXP or Shimano-fit bottom brackets.

Praxis warrants its components to be free from defects in materials or workmanship for two years from the original purchase date, to the original owner with proof of purchase. Bearings are a wear item: Praxis's steel sealed cartridge bearings carry no separate bearing warranty, and its ceramic sealed cartridge bearings carry a one-year Enduro warranty against defects. Praxis says fitting the bearings without the correct tools can damage them or the BB and voids the warranty. This is in addition to your rights under the Australian Consumer Law, so keep your proof of purchase. For warranty support, return the product to Tune Cycles and we'll manage the claim with Praxis's Australian distributor.
