Curve GXR4 Kevin of Ti Curve GXR4

Is asking $7,999

The Curve GXR4 builds on the success of the original GXR Kevin as a fantastically capable gravel bike and all round adventure bike. We have sent customers off for adventures all over the globe, from the Tour Aotearoa, the Tour Divide, Race to the Rock, or the Wilds of Mongolia! for 2024 the bike gets a few important updates, increased tyre clearance to run 700x50 frame and fork, internal dropper cable touring, increased stack and standover on most sizes, revised chainstays scale for different sized bikes and a new UDH compatible rear hanger give drivetrain options down the line. Wide Tyre Clearance The GXR has been designed with gravel cycling versatility in mind. While the GXR geometry is optimised for 700c x 44mm tyres, you can go as wide as 50 mm tyres on 700c wheels. In 700c mode with narrower tyre options, Kevin is ready for fast gravel missions, but you’ll be surprised how capable Kevin is on chunkier terrain with a 50 mm tyre. With 650b (27.5”) wheels you can move into gravel-plus territory with 2.2” tyres which offer plenty of comfort for the most rugged gravel adventures. Curve has the above wheel options in carbon and aluminium available and ready for complete Kevin builds. Ready for Adventure Our Ride 415 VGM fork has taken load carrying to the next level, with a 8 kg rating on each fork leg. That’s a total carrying capacity of 16 kg. Featuring three cleverly designed mounts on each fork leg, the Ride 415 VGM fork can accommodate anything from extra water bottles, our Rocket Pooches, or other micro-pannier or fork-specific bags. While we favour 1x drivetrains, Kevin can be set up with a 2x drivetrain without hassle. With SRAM UDH compatible dropouts, Kevin is able to handle the widest range of groupset options currently available. More Mounting Points The Curve Kevin comes equipped with rear rack mounts, fender mounts, 3 x bidon mounts, and top tube “bento mounts”. With extra tyre clearance, and a comparatively long wheelbase for the gravel genre which offers a more stable platform, Kevin is ready for epic day rides or multi-day bikepacking adventures, not just smooth gravel cruising. There is ample room for bikepacking bags on all frameset sizes
