Cranksets

SR Suntour's XCT is a replacement left crank arm for square or diamond taper-oriented cranks that features aluminum alloy construction.

Consistency in training leads to better results, which is why using a consistently accurate and reliable power meter is vital. Quarq's Active Temperature Compensation, which is calibrated with over 10,000 data points, makes their ELSA R accurate to within 1.5%. Carbon crankarms deliver the power to the road and keep the Riken light on the climbs. ANT+ technology lets you hook up your desired compatible head unit (sold separately), the LED indicator flashes when the power meter is on, and the single, easily replaced CR2032 battery lasts for up to 300 hours of ride time. - Compatible with 10/11-speed SRAM, Shimano (10-speed only) Rotor, FSA, Praxis, WickWerks, and other chainrings - Chainrings and bottom bracket are sold separately - 110 BCD

Consistency and accuracy in training lead to better results, which is why using a consistently accurate and reliable power meter is vital. Quarq power meters using Quarq technology, measure power at the crankset spider. This the best place on the bike to measure power because all of your pedaling effort flows directly through the spider and it can be measured with great precision. Quarq's Active Temperature Compensation, which is calibrated with over 10,000 data points, makes their ELSA RS Power Meter Crankset accurate to within 1.5% (strain gauges benefit from accurate temperature). Plus the ELSA RS is specifically designed to match Shimano's 4-bolt Hollowglide chainrings for a seamless junction between ring and chassis. Quarq's Exogram Hollow Carbon crankarms deliver every watt to the road while keeping the weight incredibly low. ANT+ technology lets you hook up your desired compatible head unit, the LED indicator flashes when the power meter is on, and the single, easily-replaced CR2032 battery lasts for up to 300 hours of ride time. - Compatible with 11-speed Shimano chainrings (Dura-Ace, Ultegra, and 105) - Chainrings and bottom bracket are sold separately - Requires ANT+ head unit (sold separately) - 616 grams (GXP, 172.5mm) - Battery life: 300 hours

SL-K modular BB386EVO is the latest FSA crankset for gravel, adventure, or road use. Thanks to the adaptable BB386 EVO 30mm spindle, this modular system will fit a wide variety of frames with a range of BB standards. - Hollow carbon fiber arms with UD finish - Forged AL7050 BB386EVO spindle - Direct mount outer chainring and BCD 90 inner chainrings - Chromoly chainring bolts - Fits Shimano and SRAM 10-11 speed systems

Sprint-worthy stiffness meets climb-friendly weight in Cannondale's Hollowgram Si Road Crank Set. Cannondale's One Piece Integration 3D forging is the secret to keeping this aluminum crank feathery-light and incredibly stiff. Plus, it's finished off with FSA's high-performance chainrings for flawless 10-speed shifting.

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.
