Highlights
- Light, durable SmartForm C2 Alloy Frame w/ full carbon fork
- microSHIFT Advent X 10-speed shifting / Promax mechanical disc brakes
- WTB Riddler Comp tires, 700 x 37c
A full carbon fork with a tapered steerer and 12mm thru-axles delivers a light, comfortable and precise-steering front end.
Keeps the steering light and agile, while positioning the wheel further in front of the rider for stability and confidence on rougher stuff. Plus it reduces the chance of toe overlap on smaller sizes.
Built to accept an internally-routed 27.2 dropper seatpost, which shouldn’t really be a surprise on a bike that's this off-road capable.
Bolts on when you want fenders, disappears when you don't.
