Title CR1 Crankset One Crank. Every Bike. Riders who own more than one bike know the crank compatibility headache: different spindle widths, different chainlines, different everything. The Title CR1 crankset closes the gap with an interchangeable spindle system that lets you run the same crank arms from a dirt jumper to a World Cup DH bike. The arms are fully CNC-machined from 7075 T6 aluminum and tested to the highest EFBE standard, passing TRI-TEST GR certification for enduro, freeride, and downhill use. Chainring is sold separately, and three spindle lengths cover from dirt jump spacing to a World Cup downhill bike. Features7075 T6 aluminum crank arms fully CNC-machined for high strength-to-weight ratio across gravity disciplines Interchangeable spindle system swap between 130mm, 136mm, and 145mm spindles to configure for DJ, trail, enduro, or DH frames without buying new cranks SRAM DUB bottom bracket compatible designed for SRAM DUB 29mm bottom brackets; BB sold separately SRAM 8-bolt direct mount chainring interface compatible with Title CR1 8-bolt chainrings in SRAM T-Type, Shimano HG12, and standard tooth profiles EFBE TRI-TEST GR certified rigorously tested and certified for enduro, freeride, and downhill mountain bikes Available in 155mm, 160mm, and 165mm arm lengths covers short-travel trail setups through full DH builds Specifications Speeds9, 10, 11, 12-speed (drivetrain dependent on chainring tooth profile selected)BB Compatibility SRAM DUB 29mm (BB not included)Chainring Size(s)(Not included) compatible with Title CR1 8-bolt chainrings (30T, 32T, 34T available)BCDSRAM 8-bolt Direct Mount Chainring Material Machined from solid 7075 T6 Aluminum (chainring NOT included)Crank Arm Material7075 T6 Aluminum Crank Arm Length155mm, 160mm, 165mm Chainline52mm (130mm spindle / Boost), 55mm (136mm spindle / T-Type / DUB Wide), 56. 5mm (145mm spindle / DH)Bottom Bracket Included Not Included, *Designed for SRAM DUB bottom brackets*Weight680g (165mm CR1 crank arms with 136 mm spindle, NO chainring)Intended Use Trail, All-Mountain, Enduro, Downhill | Title | Cr1 Crankset | Chrome | 160Mm, No Spindle | Aluminum
