Position One Pf24 86-92mm Bottom Bracket

Position One Bottom Bracket — PF24 Press Fit 86-92mm

Overview

The Position One PF24 is a Press Fit bottom bracket engineered for modern BMX frames with BB86 press-fit shells. The sealed bearing cartridge with synthetic resin cups minimizes weight while maintaining bearing durability. The 24mm axle diameter suits modern cranksets requiring larger spindle compatibility.

Key Features

• Press Fit design (BB86) — Presses directly into frame shell without threading; requires BB86-compatible frame shells (not compatible with BSA/BSC threaded frames)
• Synthetic resin cups — Lightweight bearing surface reduces overall bottom bracket weight without sacrificing durability
• Sealed bearing cartridge — Protected bearings resist dirt and moisture; provides frictionless pedaling with low maintenance
• 24mm axle diameter — Larger spindle diameter accommodates modern crankset standards requiring increased stiffness
• Two width options — Available in 86mm or 92mm to fit different frame bottom bracket shell widths
• Lightweight construction — 77g total weight minimizes impact on overall bike weight
