From Curve:
Kevin of Steel has been on sabbatical for a while. Not because we forgot about it. More because we wanted to get it right.
The new KOS4 keeps the same spirit as the last Kevin of Steel: a reliable, versatile, heat-treated chromoly steel gravel bike built for real adventures, long rides, rough roads, bikepacking, commuting, and whatever else you define as gravel this week.
But it has been brought properly up to date.
The geometry (geo chart found here) now follows our current titanium GXR4, our flagship gravel platform. That means a proven gravel fit, wider tyre capability, improved handling, and a higher front end on the larger sizes compared with the previous Kevin of Steel. The size range has also grown, with XXS and XXL now available in limited numbers.
Steel is not the poor cousin of titanium at Curve. We have always said, Superman was the Man of Steel, not the Man of Titanium. Steel has its own beautiful ride quality, its own feel, and will always deserve its own place in the Curve range.
Bigger Clearance & Dropper Capable
The KOS4 features increased tyre clearance, clearing up to 700c x 56 mm / 29 x 2.2” at the rear, with room for even more up front — up to 29 x 2.4” with the Ride 415 fork. KOS4 also gets a stealth dropper port on the back of the seat tube, so you can get low if the trail gets rowdy.
Now with a single sided yoke for reduced weight and retained stiffness through the bottom bracket area.
MORE Mounts
Mounting points have also been improved. The KOS4 includes rear rack mounts, fender mounts, top tube bento mounts, and five bidon mounts, including the offset down tube mounts popularised on our GMX+ model. The offset and underside down tube mounts allow riders to run three bottles while still using a full-size frame bag, even for smaller frame sizes, giving you more range on bikepacking adventures.
Including the Ride 415 VGM fork that has the ability to carry 8kg per fork leg, meaning you can be fully loaded for any adventure on the new KOS.
UDH Compatible
At the back, bespoke cast dropouts bring SRAM UDH and Transmission (T-type) derailleur compatibility to the steel Kevin platform, just like its titanium cousin. Kevin has always been versatile. Now it is more compatible with modern drivetrains too.
