favorite_borderWhy you'll love it
- Alpha Platinum Aluminium is lightweight and trail-tough
- More than fast, it's also capable: build it up the right way and this race-ready frameset can double as your light trail bike on more rugged terrain
- Internal cable routing opens the door for upgrades like a dropper post
TwistLoc Dual Remote Lockout
TwistLoc simultaneously locks out front and rear shocks with a simple Grip Shift-like motion; and it leaves room for a dropper post lever.
Control Freak cable management
The lightest, quietest, most versatile cable management system allows any combination of shift, brake, lockout and dropper post lines to be routed through the frame for clean looks and the ultimate custom set-up.
Alpha Platinum Aluminium
Our premium lightweight aluminium is continuously cold extruded and butted at multiple points, and hydroformed into sophisticated tube shapes for maximum strength and minimum weight.
Smart Wheel Size
The right wheel size paired with your frame size gives you the perfect combination of responsiveness and control.
Advanced frame geometry and a custom offset fork give our 29ers precise handling at low speed without compromising high-speed stability. We call it G2 Geometry, and it's why our 29ers handle better than anyone else's.
