Sudelfeld XC Hardtail — Race
Tax included. Shipping calculated at checkout.
QAVORYNTH Mountain — gravity, negotiated
Hardtails keep the sport's arithmetic clean; the Sudelfeld keeps it fast, with a 120 mm fork tuned for start loops and lungs.
We tune stiffness where watts live and compliance where hours live: bottom brackets that refuse to flex, seat stays that forgive broken tarmac. Each frameset is tested beyond UCI and ISO protocols before it earns a build number and a place in the queue.
Design & Build
- Fully internal routing with tool-free service ports
- Frame protection where rocks aim: downtube, stays, shuttle guard
- Wireless electronic shifting, tuned and indexed under load
- Size-specific layup — a 52 and a 58 get different engineering, not just different tubes
- Threaded bottom bracket — stiffness without creaks, serviceable forever
- Kinematics tuned per size — anti-squat that pedals, suppleness that tracks
- Room for a full-size bottle in every size — because rides are long

Can I customise the build?
Extensively: groupset, wheels, cockpit, gearing, paint.
Is a first service included?
Yes — free at 500 km in our workshop or with a certified partner near you. It keeps bearings, spokes and shifting settling exactly as they should.
