New for 2027, the Ouroboros ST is the steel version of Kona's genre-bending Ouroboros, and it's a bike that refuses to stay in its lane. Gravel bike, drop-bar mountain bike, bikepacking rig or touring machine, it's happy being any of them, and the butted Cromoly frame brings the smooth, durable ride that makes steel such a good companion on long days.

Up front is the same carbon Ouroboros fork as its carbon siblings, mountain tested, loaded with mounting points including three-pack mounts, and with clearance for big tyres. The frame uses trusted Ouroboros geometry, is UDH equipped and ready for SRAM Transmission, and comes with plenty of mounts for bottles, racks and bags.

The build is practical and wide-ranging: Shimano GRX levers and brakes paired with a Deore 10-51t 12-speed cassette and GRX derailleur, a flared Ritchey VentureMax bar and WTB Resolute 700x50 tubeless-ready tyres for grip and comfort when the gravel gets rough.
