Cranksets

An integral part of the Shimano Ultegra 12-speed road lineup, the FC-R8100 crankset builds upon Shimano's legendary front shifting and transmission efficiency. With new refinements for seamless 12-speed shifting, the Ultegra crank is now offered in a wide variety of lengths, bringing performance and improved fit for smaller riders, triathletes, and riders with specific biomechanic requirements. - Optimal balance of stiffness, strength, weight and rotational performance - Hollowglide structure cuts weight yet maintains strength for better power transfer and quicker, more precise front shifting - 148mm Q-factor - 44.5mm chainline

- Single-ring drivetrain simplifies functionality and reduces weight - Wide chainline for maximum tire and chainstay clearance - Direct mount chainring - SRAM X-SYNC wide-tooth, narrow-tooth chainring technology provides maximum chain control - DUB bottom bracket adds durability and simplicity

The SRAM RED® crankset leverages a pivotal design innovation: smaller chainrings and a wider cassette range. This leads to smoother and faster shifting up front and more useful gearing for today’s riders. The new configurations improve cadence and efficiency while also delivering shifts that are crisp, clean and quick—every time. FEATURES: - X-Range™ gearing technology gives you more range and a smoother gear progression, so you’re always in the right gear - Improved front shifting performance for crisp and accurate front shifts - Unique chainring design results in a lighter weight, stiffer, more durable crankset - DUB™ bottom bracket adds durability, simplicity and broad compatibility - Power upgradeable

Gravel bikes deserve our lightest and stiffest cranks too. The RED XPLR crankset maximizes tire clearance and features our hollow carbon arms paired with the direct mount 1x chainring of your choice. Now available in 160mm crankarm length, this crank is built to please every rider, even those who prefer the unpaved. FEATURES - Single-ring drivetrain simplifies functionality and reduces weight - Non-aero direct mount chainrings from 38T to 46T can be swapped with a single tool - SRAM X-SYNC wide-tooth, narrow-tooth chainring technology provides maximum chain control - Ultra-light hollow carbon fiber crankarms - DUB bottom bracket adds durability and simplicity - Can be upgraded to a power meter - Available in 160, 165, 167.5, 170, 172.5, and 175 mm lengths

The new Super Record 12x2 Speed crankset: an intense concentration of innovation that results in the greatest possible stiffness and precision in derailing, whilst providing a dedicated aerodynamic “super design." The new carbon fiber Super Record 12x2 Speed crankset has been made lighter on the inside through Campagnolo Hollow Technology, which uses the Ultra-Torque bracket system with a titanium axle to transfer all of the force the athlete applies to the pedal to the drivetrain. The new Super Record 12x2 Speed crankset can be installed on any type of frame, whether or not it is being used with disc brakes because it optimizes the chain line on the frame with a rear hub flange measuring 130, 135 or 142 millimeters, without affecting the Q factor, which remains constant at 145.5 millimeters thanks to the new hand crank design. The use of ceramic Cult bearings leads to obtaining the smooth ride that the Campagnolo brand is known for. The innovative design of the outer chainring ensures faster, quieter derailing owing to the contoured pin. The symmetrical design of the inner chainring teeth allows improved stability with chain crossovers. The double wheel sizing standards (112 and 145 millimeters) combined with the eight fixing screws, optimize weight and stiffness through the increased use of carbon fiber. The varying number of pins for each of the three chainring combinations (34/50, 36/52, 39/53) facilitates upshifting due to the optimized free strokes associated with each combination. The special drains on the inside of the outer chainrings optimize performance when downshifting in dead spots.
