The GT XCR 2000 is a very unique mountain bike with an eccentric bottom bracket that allows the cranks to rotate as the pivot swings forward and back. Called I-Drive, it creates a very efficient climber and allows the suspension to be active while climbing and descending. The frame is a GT's custom 6061 Easton aluminum tubing and it is paired with a RockShox SID Hydra Air 100 fork.
The Shimano XT 3x9 drivetrain is also a solid performer. With a 21" effective top tube and a 15.5" seat tube (c-c), the official size is S and this bike should fit riders in the height range of 5'4"-5'7". Shorter riders may require the seat post to be cut down.Frame Material:6061 Easton Aluminum Fork: RockShox SID Hydra Air 100 Rear Shock: Fox Float RC Drivetrain: Shimano 3x9 speed Brakes: Koski Brake Lite Pro V-brakes Brake Levers: Koski Pro Power Curve V-brake levers Shifters: Shimano Deore Mega 9 trigger shifters Front Derailleur: Shimano 3x Rear Derailleur: Shimano Deore XT Crankset: Shimano Deore XT Bottom Bracket: Shimano Handlebar: Syncros alloy riser Grips: GT Headset: WTB Momentum Stem: Bontrager alloy Seatpost: FSA SL-280 Saddle: SDG Grand Prix Wheelset: Note: bike will come with different wheels than shown in photos Front Tire: Tioga Extreme XC 26x2.10 Rear Tire: Tioga Extreme XC 26x2.10.
