It's right for you if...
You’re looking for a versatile, wallet-friendly frame set that you can build up exactly the way you want. You'll fly through singletrack, tackle rugged, all-terrain commutes or both, depending on how you spec it.
The tech you get
A lightweight and sturdy Alpha Silver Aluminium frame, internal shift cable and brake hose routing to protect cables from the elements, mounts for a rear rack and kickstand, and a headset. Designed with Smart Wheel Sizing: smaller frames fit 27.5˝ wheels and larger frames fit 29˝ wheels.
The final word
It's a light and capable frame set at great value. You can spec it as a solid cross country mountain bike without breaking the bank, or build up a rugged commuter that easily handles potholes and rough roads.

Sizing & Tech
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 retailer.
