It's right for you if...

You're a fun-loving trail rider at heart, but you also like to put the hammer down. You're sold on the advantages of the 29+ platform, and now you're looking for a serious upgrade in speed with a lightweight OCLV Mountain Carbon frame.

The tech you get

A lightweight OCLV Mountain Carbon frame with horizontal sliding dropouts so you can fine-tune your geometry or run singlespeed, super-short chainstays so you can pop off jumps and throw your bike into corners, internal routing for derailleur and dropper post, an included headset, Boost148 spacing. Designed for disc brakes, with the massive clearance to run 29+ mid-fat tires.

The final word

A fun-loving trail hardtail frameset that pairs the light weight and smooth ride of OCLV Mountain Carbon with the confidence of the 29+ platform. However you build it up, this frameset will hold its own with both the distance-crushing XC crowd and your rowdy trail-riding buddies.

Boost148/110

Boost148/110

Wider dropouts (110mm front, 148mm rear) give you the stiffness of a 27.5" wheel with all the benefits of a 29" wheel, and Boost148 in the rear lets you run wider tires and a larger chainring without affecting q-factor and pedaling efficiency.

Sizing & fit

The charts below show our recommended sizes based on height, but there are some other factors, like arm and leg length, that determine a great fit. That’s why you’ll see some overlap in our recommendations. Not every rider who’s 5´8˝, for example, will fit on the same size bike. The best way to find your perfect fit is to consult the experts at your local Trek retailer.
