New progressive geometry
For quick, nimble handling that still keeps you stable and in control on rougher descents.

Tyre clearance
Lots of clearance means you can run meatier tyres (700x45 mm or 27.5x2.1") for tackling chunkier gravel and terrain.

Tons of mounts
Integrated frame bag and mudguard mounts make it easy to carry gear and water.

Sleek internal storage
A built-in storage compartment in the downtube lets you stow tools and gear.

IsoSpeed smooth
The damped, controlled rebound of the IsoSpeed decoupler soaks up fatiguing bumps without bouncing you around.
