The new HUP GCX is our new frameset perfect for gravel racing, adventure bike packing, cyclocross or a big-tyre allroad bike. We genuinely believe, this is all the bike you will ever need. A versatile, lightweight carbon frameset on the latest geometry and standards for maximum compatability and future-proofing...
- Gravel race, adventure bikepacking, cyclocross or allroad cycling
- Frame storage plus luggage mounts on top-tube, downtube, seat tube & forks
- Big 50mm tyres on 700c for lower pressures and increased comfort
- Latest standards: T47 BB and UDH mech hanger for a wide range of groupsets
- Full internal cabling for zero fuss bikepacking and a clean, aero profile
- Option for internal cable stems or traditional stems for perfect bikefit
Using the latest (fully internal) cabling design, running full-length outer cables - ensures race reliability and reduced Winter maintenance. You can also fit a dropper post if desired. Bikes can be built using a single or double chainring chainset, including SRAM's very latest T-type directly mounted gravel groupsets, thanks to it's UDH dropout.

Alongside our new frameset, we've developed a range of components specifically for use with the HUP GCX, including; internal cable stems, carbon handlebars, T47 bottom brackets and a huge range for chainrings, so you can stay small or go big with your gearing on our HUP 2-piece cranksets.

Almost as big a project as the HUP GCX, is the range of wheels to make them fly, because no other component plays a bigger role in creating the best bike! Based on our new HUP CNC hubs, we've developed 6 new wheelsets in both Aluminium and Carbon, all lightweight (from just 1190g) and with inner widths of 23mm, 26mm or the huge 29mm - you can fit the tyres to suit your terrain. All hand-built in Scotland and UCI approved, they completely change the game.

Lastly, we have a comprehensive range of spares to support your adventures, like bearings, hangers and every conceivable nut & bolt, including a dedicated chainstay protector - formed to fit perfectly and protect your frame on that fast, off-road terrain at high speed. Because if you want to go fast, you will go fast...
