The Sight A3 boosts your All-Mountain confidence with incredible descending capability, adept, sure-footed climbing, and efficient pedaling. To make the Sight Aluminum, we had to re-think how you connect with the trail. 

With maximum front and rear wheel grip on climbs and descents, Sight A3 maintains momentum and cadence in technical situations and allows the suspension to move freely without absorbing drivetrain energy.

F


Science of Send. The Sight’s unparalleled descending capability, adept, sure-footed climbing, and efficient pedaling translates All-Mountain theory into a category smashing reality. Dynamic pedaling under rider input in a confident, stable chassis through rough terrain, the Sight elevates your All-Mountain experience.


Exact suspension tune perfects every ride. RockShox and Fox suspension components are mated to our precisely-engineered Ride Aligned™ kinematics to produce 150mm of travel in back and 160mm up front.


Drop the saddle, send the drop. Every Sight features short seat tubes for maximum standover clearance and size-specific, long-travel dropper posts to get seats completely out of the way in the rough stuff.


Sweating the little stuff makes the ride better. Full sized water bottles fit on the full size range of every 27.5" and 29" model. Supportive side-wall 2.4” and 2.5” tires are equipped, but there’s clearance for up 2.6” because details matter. All of them.


Details that make a difference. Custom frame protection and a new shuttle guard protects each Sight from long, rowdy days on the trail and when it’s hanging off the back of your buddy’s pickup. Under-top tube mounts provide easy mounting for some of the most popular aftermarket storage bags or accessories.


Exactly the speed you need when you need it. Every Sight features 4-piston hydraulic disc brakes and 200/180mm rotors to hit the perfect line on every ride and pull you back when the ruckus gets a little out of hand.
