Meet 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 wide gravel tyres in two wheel sizes and stiffens the BB area to avoid excessive frame flex under load.

More Mounting Points

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.

Ready for Adventure

Our Ride 400 fork, originally titled GXR fork, was built to complement the Kevin of Steel and titanium GXR frameset. Featuring 3 x 12 mm M5 mounting points on each blade, the Ride 400 fork can accommodate anything from extra water bottles, our Rocket Pooches, or any other micro pannier or fork-specific bag.
There is ample room for bikepacking bags on all frameset sizes.

Want to Carry More?

With a wide range of frame and fork mounted rack systems on the market, and with more appearing every week, it is important to understand which rack systems are compatible with your Curve frame and fork, and how to mount them correctly in order to ensure safe riding, avoid damage and voiding your warranty. Before mounting a rack, we strongly recommend you get in touch with us to confirm compatibility and the correct mounting procedure. This will minimise the risk of injury, product damage and voiding your warranty. Your local Curve dealer, or the team at Curve HQ, can also help you select a rack system and mount it to your bike for you.

All bikes purchased from iRIDE will have been pre-assembled by our mechanics and test ridden. You will also receive a multi point checklist of all the safety checks and bike build elements we work through to ensure you bike is correctly assembled, and then tested so that it runs as it should. Bikes being sent to a customer who is unable to collect it from iRIDE, will have it boxed, wheels, saddle and bars generally off and re-packaged.

The delivery of bikes will be organized once a freight fee can be determined based on weight and delivery location.

Assembly should take no longer than 10-20 minutes. It is recommended that a skilled mechanic assemble, or check the bike. If possible your local bike shop is likely best placed to do this from a safety perspective to ensure all is as it should be. If a rider is having any issues we can hook up an online video chat, or talk over the phone. If this service is required email us at workshop@iride.net.nz to organise a time that suits all parties.
