Norco Sight A3 MX Bike A Sight To Behold All-mountain bikes are great at many things. If you're interested in descending as fast as possible and hitting a jump or two on your way down, then you'll love riding an all-mountain bike. They're perfect for getting gnarly on technical singletrack and climbing back to the top to do it all over again. The Norco Sight A3 MX Bike has an increased rearward axle path, an idler, and a high pivot horst suspension layout that gives the Sight next-level confidence and capability, up or down the mountain. The aluminum frame uses 160mm of travel on the front and 150mm of travel on the rear. It also has a large 29" wheel up front for roll-over capability and a 27. 5" rear wheel for enhanced control. The frame features a Ride Aligned design, a long travel dropper post compatibility, a threaded bottom bracket, internal cable routing, and integrated frame protection. The A3 version of the Norco Sight comes with a Shimano Deore 12-speed drivetrain. This includes a cassette that has an ultra-wide 10-51T gear range that makes climbing and pedaling through difficult terrain much easier. Shimano Deore MT520 4-piston hydraulic disc brakes provide excellent stopping power so you can confidently descend. Stan's Flow D rims are paired with Maxxis Assegai and Minion DHR II tires that can be set up tubeless for a smoother ride, better traction, and fewer flats. With the Tranz X Dropper Post, you'll be able to quickly lift and lower your saddle with the press of a lever.
