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. * See FAQ No Weird Flex The custom titanium yoke design allows Kevin to run wide gravel tyres in two wheel sizes and stiffens the BB area to avoid excessive 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 (44t max) or 2x (50/34t max) drivetrain. Kevin is ready for single or multi-day bikepacking adventures due to extra tyre clearance, a longer wheelbase, and a more stable platform.There is ample room for bikepacking bags on all frameset sizes. To make sure current, prospective or custom bagging fits your frame size please see our Bagmaker Drawing page. 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.
