Four

Our jump bike frame is designed to reflect the needs of our friends, who happen to be some of the most dedicated trail builders and riders out there. Most of them were reluctant to move on from the 24” wheel size which has been abandoned by the mountain bike industry.

Beyond that we’ve employed some BMX technology with a Mid BB and integrated chain tensioners. Butted chromoly tubing and tapered chain and seat stays which aren’t crimped and have eye pleasing curved bridges.
