Curve - AIR Kev Frameset

The Fastest Kev Yet

Introducing AIR Kev, the gravel-race version of our beloved GXR (aka Kevin). This is Curve's tribute to a trail-blazing hero, our most popular model; a revolutionary bike in the burgeoning modern gravel scene. AIR Kev was originally a project for the 2023 Handmade Bike Show Australia, but it quickly won the hearts of gravel fans across the globe, so we decided to bring it to life.

AIR Kev combines the best qualities of carbon and titanium to create a new standard for gravel riding in the Curve range. The carbon seat tube is not just a striking design feature, in combination with the 3d printed titanium BB lug, it results in the stiff and responsive ride quality you'd expect from a top-end race-oriented frame. The carbon seat tube is bonded to the bottom bracket shell with a super strong double-lap join. A tight tolerance 3D-printed titanium lug, and a carefully selected aerospace adhesive, makes this possible. Our 3D-printed parts include sub-millimeter bond-gap control features. While such fine details are invisible on our finished frames, they result in class leading bond strengths. Complete AIR Kev builds are finished with Curve's new carbon seat post with a custom 3D-printed titanium topper. This post weighs a respectable 190g without compromising performance.

The AIR Kev frame features internal routing via the downtube, bottom bracket and full-length non-drive side chainstay. The brake hose has an uninterrupted path from front to rear for clean RH-rear or LH-rear brake controls. It is held in place by an unsung hero, a 3D-printed titanium cable guide hidden inside the bottom bracket shell, which secures the hose snugly without bottom bracket cup or crank spindle interference. A single-sided yoke remains together with the curved seatstay to retain the iconic side-on silhouette of the original Curve GXR. AIR Kev features a stripped-down version of our Ride 415 fork, dubbed the Race 415 fork, with internal brake hose routing and without M5 cargo mounts.

While the AIR Kev is built to go fast, all Kevs are ready to party on chunkier gravel. The AIR Kev frame and Race 415 fork can accommodate a maximum tyre clearance of 700c x 50mm, and even wider up front, giving you plenty of options for all-terrain adventures. AIR Kev is also compatible with 650b wheelsets if you want to venture further off the beaten track. The rear dropouts are fully SRAM UDH/T-Type compatible, for the ultimate wide gear range builds. The flat-mount brake tab is positioned for a 160mm rotor without the need for an adapter.

This AIR Kev complete build features our newest G4T option, the super lightweight hookless hill crusher wheelset. The 25 mm depth profile keeps the weight low while the 22 mm internal width allows a large cross-section of road/all-road/gravel race tyres to be fitted and set up tubeless for a true "riding on a cloud" experience. Configured using the top-tier DT Swiss 180 ceramic EXP hubs and Sapim Super Spokes, this stunning wheelset is finished with robust Sapim brass nipples to create an ultralight yet reliable wheelset. These wheels tip the scales at a feathery 1,158g (taped, with valves and valve caps).
