Curve Cycling
GXR (AKA Kevin)






Meet our GXR a.k.a. Kevin
Our titanium GXR, paired with the Ride 400 carbon fork has been tested heavily on adventures worldwide. Many of the Curve team have traversed South America, New Zealand, Switzerland, Swaziland, and more on this magnificent bicycle.
Originally a playful jab at the bike industry's bike naming terminologies, the name ‘Kevin' was coined to name this frame. it soon caught on, and we simply couldn’t resist making it official.
-
Two Bikes in One
The Ride 400 carbon fork has clearance for wheel options based on your riding style. For example, Kevin can run either 700c wheels with 32–45 mm tyres, best suited for commuting, gravel, and cyclocross, or if you’re looking to tackle some rougher terrain with more traction, use 650b (27.5”) wheels fitted with 1.8–2.2” tyres. Curve has the above wheel options in both carbon and aluminum available.
-
No Weird Flex
The custom titanium yoke design allows Kevin to run some super-wide gravel tyres in two wheel sizes and stiffens the BB area to avoid frame flex under load.
-
Ready for Adventure
Kevin comes equipped with rear rack mounts, fender mounts, and 3 x bidon mounts; and can run either a 1x or 2x drivetrain. Kevin is ready for single or multi-day bikepacking adventures due to extra tyre clearance, a longer wheelbase, and a more stable platform.
-
Front Rack Ready
If running a front rack on Kevin, please keep in mind that the fork is designed to carry a max weight of 6 kg (3 kg/ blade) - a bit of jiggery is required when installing a rack - you will need a bracket that allows the rack to attach to both the front and rear mount on the fork crown to ensure the rack is securely in place.
