HUP straatrace Road Racing Frameset


Brand HUP™

***Now updated to Disc Brakes***

What's new on the updated HUP straatrace? Well quite a bit! Now with Flat Mount disc brakes (hydraulic or mechanical options), dropped seat stays for increased rear compliance, lighter rear triangle tubing to reduce weight, clearances for up to 30c tyres (swap to off-road tyres for grass course Triathlon) and now available in 8 sizes for riders from 120cm+ up to around 6ft 1" tall - with a choice of Racing Red or Cool Grey colours...

The new disc-braked HUP straatrace is the lightest child-specific road frameset on the market, using unique XXS geometry to fit smaller riders correctly, based on full-sized 700c wheels. Lightweight, low-standover and low stack, this unique frame is suitable for up to 30c tyres,ready for the Belgian cobbles!

It's not just great for Road racing, it's also perfect for youth Triathlon - as the wide clearances have been designed to take a cyclocross tyre! Whilst it's not designed for the mud of a CX race, it's perfect for using knobbly tyres for proper grip on grass courses (slick road tyres on early morning, wet grass are so risky). Simply change back to a slick road tyre for Triathlons/Duathlons running on tarmac - we've designed this bike to can cope with any Triathlon course.

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 125cm 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.

Included with this frameset: frame, fork, headset, mech hanger, axles, BB cable guide & cable fittings. Components available separately. HUP framesets are handmade/painted in Taiwan.
