Part No.  37736
load-spinner
Fixie freestylers' demands are particular, and the P.Fix was put together by some of the best riders on the scene. The lighweight, tough double butted Reynolds 520 frame is lively, but tough, and the parts spec won't let you down - fixed/freewheel convertible hub, triple void alloy rims and custom parts created for real riders. Take that, hipster poseurs.
  • BMX-style, 3-piece tubular Cr-Mo crankset with cartridge-bearing MID BB is strong and light to go big with confidence, singlespeed 25t chainring resists bending and delivers the clearance you need
  • The Cr-Mo P.Series MTB Street handlebar is 720mm-wide for more leverage and precise handling
  • Press-in MID BB is lightweight, durable, and easy to service with sealed cartridge bearings and 48-spline spindle
  • Super-light and durable P.Series SL one-piece saddle/post combo offers both light weight and comfort
  • Lightweight NYLON plastic P.Series platform pedals and P.Fix retention straps keep you connected to the bike
  • One-piece, 10t cog is convertible between a fixed gear or freewheel setup
  • Butted, single-speed-specific, Reynolds 520 Cr-Mo frame with integrated headset, MID BB, and 3D-forged horizontal dropouts with integrated chain tensioner has perfectly dialed geos for fixed-gear freestyle
  • Ride dirt, park, or street on the Specialized Compound Street tires with low rolling resistance and a rounded profile
  • P. Series butted and taper blade Cr-Mo fork is light yet strong enough to handle heavy abuse
  • Lightweight 36-hole wheels with bolt-in female axle front hub and proprietary convertible fixed/freewheel, cartridge bearing, 14mm hollow axle to convert from fixed to freewheel
