HUP azure Track Frameset
The new HUP azure is the lightest child-specific track frameset on the market, using unique XXS geometry to fit smaller riders correctly (making it perfect for beginners and first time track riders) based on full-sized 700c wheels. Lightweight, low-standover, low stack and very fast, its ready for the Ghent Velodrome!
With a lightweight triple-butted 7005 frame and carbon fork (when built with HUP cranks) for the first time younger riders benefit from correct length/q-factor crank arms to match the high cadence required in a lightening fast velodrome race. At last, a track bike frame that fits children properly.
HUP azure track 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 650c wheels!
HUP framesets have been specifically developed for children's long leg/short torso physiology with short top-tubes (just 48cm 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 examples above are a standard build 44cm @ 7.3kg (rider height 148cm) and a custom-build 37cm @ 6.8kg with pedals (rider height 130cm).
Included with this frameset: frame, fork, headset.
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.
