Introducing the Hook EXT C
Our carbon fibre Hook EXT C gets a new frame and fork. Along with tweaks to the geometry, we’ve added our full-carbon EXT V2 fork with triple cage mounts. Also coming with an updated build-kit, Sram now provides the bike’s XD cassette to impart a huge 10 – 42 T gear range. Taking care of the hoops, our friends at Hunt send over the tubeless-ready Adventure Sport 27.5-inch wheelset. Finished with great-looking tan-wall WTB Venture tyres, this agile adventure bike is the perfect companion for technical backcountry raids.
