Blackthorn 145 C Deore 12 is an all-mountain bike that thrives on big rides over rowdy and unpredictable terrain. Its stiff carbon frame gives you more power per pedal stroke, while our all-mountain geometry balances downhill composure with pedaling comfort for a bike that does a little of everything efficiently.

Blackthorn’s Split Pivot suspension adds to its efficiency with a design that pedals exceptionally well and maintains traction even while braking through your full range of travel. With 145mm rear travel and a 160mm fork, you can lean into those coming-in-hot moments without losing control.

On-bike cargo mounts let you rethink the need for a hip pack: mount two bottles, your multitool and tube, plus our EXP-R Series Trillium Top Tube Bag or a K-Edge computer mount directly to your frame to stay supplied on more remote rides. Shimano’s Deore 12-speed drivetrain is a reliable workhorse with components you rarely have to think about.

  Frame Protection

  • Our products are built from experience — we’ve been there enough to know that a carbon fork can benefit from added protection just as much as the downtube on a suspension bike.
