Full suspension opens up a whole new world of speed and control off-road. Modernized with 27.5” hoops, this is the frame platform that’s won us numerous industry accolades and Bike of the Year awards. Perfect rigs for the experienced rider who is looking to upgrade to their first dual suspension or for new riders looking for a head start in performance.
XC MP2 SUSPENSION
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 tapered 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 standard 1 1 /8” systems.
ASYMMETRICAL CHAINSTAYS
The Dakar’s chainstays are asymmetrical, with an elevated straight stay on the non-drive side and a dropped curved stay on the drive side. The drive side must be dropped & curved to clear the front derailleur and chain, but running the non-drive side straight from the dropout to BB pivot reduces weight while significantly stiffening the rear triangle laterally. There’s more tire clearance, too.
TUBELESS
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.
STOPPING POWER
Top-notch braking shouldn’t break the bank. Shimano’s M396 & M315 hydraulic brakes offer the power, the smooth modulation and all-day, all-conditions reliability.
AIR SPRING SUSPENSION
The Dakars feature air spring suspension that offers adjustable compression and rebound damping and a single air valve. It’s light and easily adjusted to suit rider and riding style.
ONE AND ONLY
The 1x drivetrain philosophy is to make it simpler, lighter and more durable. Specific chainring tooth profiles, clutch-type rear derailleurs and wide range cassettes are developed for an incredibly wide gear range and maximum control without the need to chain tensioning devices or guides.
VITTORIA
Vittoria has made a strong name for itself in the offroad world as Geax and its’ Goma tire is the ultimate trail tire. Leading edge ramps, multi-directional siping, defined side channels and stepped side knobs make this tire grip in every condition, while still rolling fast.
