Product Details

SRAM X7 Type 2, 10-speed, rear derailleur for precise shifting
Custom 2x10 crankset and drivetrain for efficient and precise shifting
Stout XC 650b aluminum rims with 21mm inner width rims are trail ready
120mm-travel custom SR Suntour XCR-AIR fork w/ exclusive Multi-Circuit Damping for smooth performance
Specialized Ground Control 2.3" tires w/ a fast-rolling yet grippy tread
A1 Premium Aluminum frame w/ ORE downtube for a lighter, more compliant, and durable bike
