What They Say...

One of the first gravel-specific bikes released, the Curve GXR model has been around since well before gravel became cool. Now, with wider tyre clearance, improved mounting options and UDH compatibility, the latest version of our Swiss Army Knife of bikes is more versatile than ever.

We have been ahead of the Curve when it comes to gravel, and the GXR has years of adventure cycling experience woven into its DNA. The Curve titanium GXR has been tested heavily on gravel adventures worldwide. Across South America, New Zealand, Switzerland, Swaziland, and more, the Curve squad has traversed the globe on this magnificent bicycle.

Originally a playful jab at the bike industry's bike naming terminologies, the name “Kevin” soon caught on, and we couldn’t resist making it official. Kevin, the reliable Aussie all-rounder, is here to stay as a permanent nickname for our beloved GXR.

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.
