Karakoram 4.0 Mech
This bike respects your skills. Steep descents, rocky climbs, and jeering friends can make any ride feel like a challenge, both to your skills and to your ego. Fortunately you perform under pressure, and you’re on a Karakoram, which is just as relaxed in a crux as you are. Responsive, indestructible, and smooth on the trail, it’s all the bike you need to show your buddies the skills it takes to be a bad ass.

Independent Drivetrain™
This suspension does its job. Period. Because it operates independently of the drivetrain, the suspension can focus solely on its intended purpose – a smoother, faster ride – without making compromises in pedaling efficiency. And because it’s an inherently simple design, it’s easy to set up, ride and maintain. Sound good? Good.

Triple Triangle™
Originally developed to extend the frame life, stiffen the rear triangle and thus create a faster, more responsive ride, the Triple Triangle™ frame has transcended its role as just another tech story and become an iconic symbol of who we are and what we stand for.

Forged Elements
We forge every single linkage and pivot on all of our dual-suspension bikes. We also forge areas of the frame that are prone to stress or abuse, such as head tubes, bottom brackets and dropouts.

Light on grams, not on performance. These forged construction head tubes are as capable of handling marathon trail sessions as they are of chasing points on the XC pro circuit.

Comments about gt Karakoram 4.0 Mech:
This is my first real trail bike. Nice and rugged. No big jumps, but plenty of downhill bombing on lumpy, rough trails. Easily ridden on the road, but very tight and grippy on the trail. Not too heavy when carrying it over or up an obstical. Accurate shifters and good brakes without breaking the bank.
Lost the chain a few times when riding down stairs and very bumpy trails. Needed to tune the controls and brakes several times when I bought it. Once I set it up for my preference, it was fine. Bent the derailer hanger when I slammed into a stump. The replacement hanger was a little expensive.Displaying reviews 1-2
