Overview
About this bike
The SixFifty 3500 features a double-butted alloy frame with 120mm of travel for fun rides on everything from buffed singletrack to technical trails that challenge your balance and stamina. Front and rear suspension are controlled by an RST First fork and X-Fusion O2 Pro shock, and a 27.5-inch WTB tubeless-ready wheelset paired to Maxxis Ardent tires keeps you on track thanks to nimble handling and excellent traction. Shimano's SLX 11-speed drivetrain shifts smoothly to keep you in the flow, and you can count on Shimano hydraulic disc brakes to put down ample stopping power when you need it most. A Kore XCD handlebar and stem combo and WTB Volt Sport saddle top this build.
