Fancy machined yoke for tons of tyre space even with 29 x 2.6in rubber.

Short seat tubes mean you can size up and put your front end in a different postcode if you want.Super steep seat angle and long chainstays for winching back up the steepest slopes for another go.Boost spacing and forged and machined chainstay sections for masses of mud room even around 29x2.6in tyres.

Bolt through axle for security and replaceable gear hanger for when you bend it. External cable routing and ISCG chainguide ready BB for the smoothest operation and simplest servicing. No rack mounts because it's made for psychos not cargo. 3 colours or lacquered raw finish for naked build detail appreciation.
