Past meets present in Kona’s new genre-blurring platform
Brilliant bikepacking chops
Exciting handling
Comfortable rear end
Lots of mounts
180mm disc brake rotors should be the future
Sram udh dropout
Competitive but mismatched tyre clearance
Strange frame sizing
2x groupset is at odds with the big tyre clearance
Ritchey venturemax xl handlebar ergonomics

Kona offers the adventure focused crowd a fairly-priced, high-value package that excels in tricky terrain well beyond flat, straight country roads.

The Kona Ouroboros is not your typical gravel bike. For technical mixed-terrain riding, it could be your dream bike. See our full review.
Confident off-road position with short stem, wide bars, front suspension, and dropper post
Big tires add traction
Suspension fork absorbs small bumps and keeps wheels planted
Dropper post and wide bars aid descending
Adventure-oriented build with 40mm suspension and dropper post
Weight at 23.1 lbs is a burden for lifting and accelerating
Not nimble for tight cyclocross courses due to long wheelbase and slack front end
Requires steering correction in tight turns on road
Acceleration lackadaisical due to big tires and heavy wheels
Wide handlebars can clip posts or trees on narrow sections

"By design, the Ouroboros lives somewhere in the murkiness between mountain and gravel bikes"
Excels on rough, chunky, slow, janky, undulating XC-ish trails where traditional gravel bikes struggle
Fun on singletrack side trails and encourages little side hits
Long-travel dropper post with sloped top tube aids descending fun
Gives up little on tarmac and smooth dirt compared to traditional gravel bikes
Comfortable upright geometry for relaxed riding
Wide tire clearance (rigid variant fits 2.5" tires)
1x drivetrain simplicity with wide range (SRAM Apex 12-speed)
Compatible with SRAM Eagle mountain derailleurs for upgrade
Touch points (saddle, bar tape, bar width) not ideal for reviewer
Stock KS dropper post lever needs replacement
Stock wheelset heavy and stiff (upgrade to Shimano GRX improves responsiveness)
Not as snappy and responsive as traditional gravel bikes
High stack height, upright riding position may not suit all
Sizing is tricky due to unusual geometry; recommended to test ride
Apex shift quality not top-tier

Inspiring geometry
Carbon gives life to geo
Snappy ride quality
Loads of bikepacking provisions
Good-looking frame
No rear rack our down tube mounts
Press fit BB
More clearance would be nice
Stiffer rear end rattled me a bit
