Procaliber SL is for the fastest XC riders. It's built with Super Light OCLV Mountain Carbon and delivers the unique trail-smoothing advantage of IsoSpeed, which takes the edge off fatiguing bumps in the trail so you can stay stronger longer.
  • This SL OCLV Mountain Carbon frameset is the ideal start to an obscenely lightweight cross country build
  • The IsoSpeed decoupler makes it ride smoother than any other hardtail, so your body doesn't get beat up by trail chatter
  • Control Freak Cable Management allows you to run any combination of cables exactly the way you want, while still giving you sleek looks and protecting your cables against unnecessary wear
  • Boost148 spacing for 29" wheels on all frame sizes except S, which has a 142x12mm rear axle and 27" wheels
