A 27.5x3" tire measures out to a 29" diameter and a 26x3" tire measures out to a 27.5" diameter. COmbining whem with a 40mm rim, results in the ultimate combination of traction, roll-over and versatility without being too heavy, too bouncy, too tall or feeling letharigic on the trail.

Tapered Head Tube

Riding fast with control requires steering precision, which starts with the front of the bike. Stiffening this area results in less wheel deflection, more wheel control. A full 1.5" tapers 1 1/8" to 1 1/2" head tube serves up a significant increase in rough terrain tracking and stability without much of a weight penalty compared to a standard 1 1/8" systems

Short Chainstays

The rear wheel tucks in with short chianstays. With a 12x148 rear hub, you've got a stiff and responsive rear end.

Outboard Chain Line

A 12x148 rear hub with 3mm offset chain rings minimizes the chance of chain to tire contact with short chainstays and "mid-fat" tires without compromising and pedaling efficiency to a wider q-factor.

Why Thru Axles?

Securing the rear wheel to the frame by threading a 12mm axle into the rear drop-outs is not only safer, its stiffer. The rear wheel tracks directly in line with the frame, for more precise handling, so you can go faster with more confidence. The increase in stiffness of a 15mm fork axle improves steering and handling significantly. It also puts less stress on the fork's internals, improving for durability and performance. The hub drop puts provide a self-centering feature for the wheel for fast, easy installation.

Forged Bottom Bracket Yoke

A one-piece bottom braket shell and drive-side chainstay yoke provide a strong and lightweight solution for the potential clearance issues of 3" tires and double chainrings.


Benefits of a tubeless set-up are reduced rotating weight and the ability to use lower inflation pressures for greater traction without the risk of pinch flats. WTB TCS rims feature a tubeless UST "On-Ramp" profile providing a consistent fit between the rim and the tire for easy installation and inflation

180mm Front Rotors

Bigger wheels and tires generate more rotating mass and traction once they are up to speed. So it only makes sense to use larger rotors to help control that larger wheel in the most efficient manner possible. Sure, 160mm rotors will stop the bike. But when you're riding like every second counts, braking for the shortest time possible while keeps the bike under control is the goal. And a larger 180mm rotor up front let's you do this.

Seat and Steering Platform

A 35mm seat tube with 31.6mm seat post assures the stiffest possible pedaling and steering platform, with a sloping top tube for low stand-over.
