Meet Kevin, aka the Curve GXR gravel adventure do-it-all bike.
We have taken the fun of a cyclocross bike, fused in some adventure feels and rolled it into one neat do-it-all package that can take you anywhere.
Curve GXR
Two Bikes in One
The GXR 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 aluminium available.
No Weird Flex
The custom yoke design allows Kevin to run some super-wide gravel tyres in two wheel sizes, and also stiffens the BB area to avoid frame flex under load.
Adventure Ready
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.
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.

FAQs
| Where can I test ride a GXR? | Contact us to book a time to pop into Curve HQ, Melbourne, or check our stockist page to contact your nearest Curve retailer. |
| What are the main differences between a GXR and a Belgie Ultra? | If you want to do more gravel and trail then the GXR is the better fit! The Belgie Ultra is good at light gravel but is more of an endurance road bike. The GXR (Kevin) is great both on and off-road. It just depends on if you are going to spend more time on the road or if you want the added versatility of a gravel-specific bike that can run multiple wheelsets. The Ultra is limited to max 700c x 32mm tyres. |
| When shipping direct, how does a complete bike come finished to me? | Each bike is built and boxed to "90% complete" with the fork steerer uncut and bar tape is not wrapped. We do this so each individual can personalise their setup options. This final procedure should be performed by an experienced bike mechanic. |
