Curve GXR (aka Kevin)

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.

700C or 650B

Choose the wheels that suit your cycling style. Kevin can run either 700c wheels with 28–45mm tyres for Road/Gravel/Cyclocross or go full HellCat with 650b (27.5”) wheels running 1.8–2.2” tyres. With two wheel options, you effectively have two bikes in one. (We make both sizes in carbon and alloy options.)

 Custom Machined Yoke

Liam, our engineer, spent many hours swearing at his computer while perfecting Kevin. 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 is up for anything. Every Kev comes equipped with rear rack mounts, fender mounts & three bidon mounts; it has the ability to be configured with Di2 or mechanical drivetrains, and single or double (compact) chainrings. With huge tyre clearance across two wheel sizes, a longer wheel base and a more stable platform; Kevin is perfect for day trips, weekenders and multi-day cycle touring. But Kevin still rips when you strip it back for a CX Race or Belgie ride!

Kevin is not like other bikes: he’s a little longer and a little taller to create more space for frame bags and 1L water bottles. Kevin is designed to run a shorter stem and wider drop bars to maximise handling efficiency.

Gravel bikes are different to road bike geo, so the numbers on the chart may blow your mind. Generally, a Medium Kev will be equivalent to a standard 54cm frame. Get in touch if you need help with sizing.
