Press fit creaking and short-lived bearings are a common gripe. Hope's PF41 answers it with bearing cups that thread into a centre tube, locking the assembly together in the frame for a secure, quiet fit.

Highlights

  • Cups thread into a sealed centre tube for a secure fit
  • For 41mm press fit shells with 30mm crank axles
  • Custom-designed, Swiss-made stainless bearings (2024 update)
  • External bearing shields
  • Convertors included for 29mm crank axles
  • Easy to service with replaceable parts

Updated for 2024

Hope's 30mm PF41 now uses a custom-designed, Swiss-made stainless bearing, allowing a full assembly with a fully sealed internal centre tube and external bearing shields. Hope quotes 77g.
