- Featuring a tapered head tube, 142 x 12mm rear axle and 15 x 100mm front axle and clearance for 2.5" tyres.
- CNC machined one piece BB yoke, dropouts and brake mounts for increased strength in these key areas.
- High quality 6061 hydro-formed, T6 heat treated aluminium tube set.
- Square rear drop out tubing for maximum stiffness and weld area whilst allowing better ankle clearance.
