HUP xc MTB frame

The HUP xc is a lightweight hardtail MTB for cross-country racing, trail smashing or adventure fun times. Born and raised at the UCI MTB World Champs in Glentress, Scotland in 2023, it's a double-butted 7005 frame with boost thru-axles, UDH hanger and XC race-focused geometry. A rocketship for riders age 7+

• Progressive Geo: low standover, slack 67º fork, short stays and 100mm or 120mm forks
• Full Size Wheels: 27.5" (13") or 29er (15", 17" 7 19") running up to 2.4" tyres
• Lightweight: strong, double-butted 7005, UDH hanger, in 4 sizes and as light as 9.5kg builds!
• Custom Components: custom length cranks, droppers, big gearing, hydraulic brakes (+upgrades as they grow)
• Quality Throughout: only top brands including SRAM, FSA, Jagwire, Fulcrum, Rockshox, Manitou, Tekro & KMC
• Build Flexibility: frame only, self-build bundles (with/without wheels/fork) or individual components or use your own parts

Lightweight for the climbs, but still capable of technical descents, as found in modern cross-country race courses and bike park trails. The low standover/low stack gives riders the space to move on the techy sections and keeps their shoulders down on the fast sections. Big wheels, latest progressive geometry (short chainstays) and correct fitting components create an agile, responsive and seriously fun bike. The squad had a riot developing these in Glentress forest.

With 4 frame sizes covering riders from approx 125cm up to approx 185cm tall, you can move their components to a larger frame as they grow, just like all HUP bikes. Parents also benefit from component sharing (life is simple with everyone on the same size wheels!) and makes future upgrades much easier too.

A low maintenance design with full length outer (internally run) cabling (including the option to fit a dropper post) plus the latest standards such as Boost thru-axles, 2.4" tyre clearance and a tapered head tube - ensures future compatibility. SRAM's Universal Deraillieur Hanger system (UDH) also brings the ease of a widely available hanger, plus the ability to fit the very latest AXS Transmission type groupsets. Full-power shifting on the flat-top chain is a game-changer. We love it.

Included with this frame: frame, headset, mech hanger, thru-axle & cable fittings. Self-build bundles or components available separately. HUP frames are handmade/painted in Taiwan. Frame protection tape is highly recommended.
