HUP straatrace Road Racing Frameset
The new HUP straatrace is the lightest child-specific road frameset on the market, using unique XXS geometry to fit smaller riders correctly (perfect for young racers) based on full-sized 700c wheels. Lightweight, low-standover and low stack, this unique frame is suitable for 25c tyres - ready for the Belgian cobbles...
With a lightweight triple-butted 7005 frame and full carbon fork, the #HUPstraatrace uses the latest internal cable technology with easy fitting for novice mechanics thanks to a downtube 'letterbox'. When built with HUP cranks, riders benefit from the correct length/q-factor to match the high cadence of criterium road races.
HUP straatrace road frames start with the tiny 37cm for riders as small as 128cm tall. Performance benefits of younger riders on 700c wheels are well proven and the practical benefits of component sharing with their parents and siblings is a game-changer. No more odd sized 24" or 26" wheels!
HUP framesets have been specifically developed for children's long leg/short torso physiology with short top-tubes (just 47.9cm long for the 37cm) and when built with HUP components, achieve unrivalled fit. Framesets are so lightweight, depending on build spec, UCI minimum weight bike builds are realistic. Photo example above is a custom-build 37cm @ 6.8kg with pedals (rider height 130cm). Standard 10sp Microshift builds are approx 7.9kg.
Included with this frameset: frame, fork, headset, mech hanger, BB cable guide & cable fittings...
