HUPcc CX HUP Evo Cyclocross Disc Frameset (Kids Sizes)

The new HUP evo is a game-changing Cyclocross disc frameset, using unique XXS geometry to fit smaller riders correctly, based on full-sized 700c wheels. Lightweight, low-standover and low stack, this unique frame allows riders of all ages to shoulder easily with it’s curved, flat bottom top-tube – Koksijde ready!

This clever frame design can deal with serious mud, thanks to it’s class-leading 55mm clearance, which also allows the fitting of 650b wheels & 46c tyres. Flat Mount disc brakes produce all-weather braking reliability. Stiff, lightweight thru-axles (just 80g per pair) and a long trail layout increase high-speed stability. A superlight monocoque carbon fork creates a very light front end, improving manoeuvrability especially for smaller/lighter riders.

With a triple-butted 7005 frame and full carbon fork, the 37cm #HUPevo is the lightest frameset available, using the latest internal cable technology with easy fitting for novice mechanics thanks to a downtube ‘letterbox’. Running full-length outer cables ensures race reliability and reduces Winter maintenance to a minimum.

HUP evo CX frames start at 37cm for riders approx 125cm tall upwards. 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 well known too. No more odd sized 24″ or 26″ wheels! Even smaller riders can fit our straight bar builds, especially when built on the optional 650b wheels (offering real flexibility as the rider grows) creating very capable MTB XC race and Gravel bikes.

HUP framesets have been specifically developed for children’s long leg/short torso physiology with class-leading short top-tubes (48cm for the 37cm, approx 3cm shorter than the ‘competition’!?) and when built with HUP components, achieve unrivalled fit. It’s the frame kids want to ride, at the price parents want to pay! 

Included with this frameset: frame, fork, headset, mech hanger, thru-axles, BB cable guide & cable fittings.
Self-build bundles or components available separately. HUP framesets are handmade/painted in Taiwan.

*Unlike many brands, we quote weights (subject to manufacturing tolerances) and you should always compare full frameset weights for a real world comparison as most brands play a game: quote light frames, but supply heavy alloy steerer forks, thru-axles & headsets! HUP doesn’t play games, but we do build light bikes.
