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"
Unique blend of gravel and mountain bike characteristics
Excels in rough, chunky terrain where conventional gravel bikes struggle
Long dropper post enhances descending fun
Upright geometry offers comfort for relaxed rides
Good tire grip with Maxxis Ravager
1x drivetrain simplicity with wide range
Touch points (saddle, bars, tape) not ideal for reviewer
Stock KS dropper lever recommended to be replaced
Wheelset heavy and stiff; GRX upgrade costly
SRAM Apex shift quality not top-tier
Not as snappy/responsive as traditional gravel bikes
Geometry sizing tricky; test ride recommended

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
