Wolf Tooth designed these bolts to be the best on the market. These optimized single chainring bolts have a 4mm hex socket on the bolt and a 6mm hex socket on the nut...that's right, no more spanner for your single ring bolts! These are 6mm long so they work perfectly with any bolt on single chainring that does not have threaded standoffs. - 6mm length - Made in the US out of 7075 Aluminum Alloy - Has hex heads on both the bolt and nut for easy installation - Max torque of 6-7 Nm with light grease on threads only
Designed to work seamlessly with the new wave of 2×10 drivetrains, the 2x utilizes MRP's patented integrated skid chainring protection (US Patents RE 42,436 / 8,235,849 Patents Pending) and features a dual pulley tensioning system. Notable on the 2x system is the absence of a crank-mounted bash guard or guide ring, instead it relies on the front derailleur and cutting-edge lower pulley assembly for complete chain retention. The integrated skid protects the chainrings from impacts without the added weight of a full bash ring. The dual pulley tensioning system ensures that the chain is properly tensioned and in the right position, keeping it on the chainring in the roughest conditions. The dual pulleys also reduce drag and noise compared to other designs, ensuring a better riding experience. Finally, the raised top fin profile prevents the chain from dropping to the BB shell. - Removable integrated skid protects chainrings and glides over rocks and obstacles - Dual pulley design provides precise chain engagement while reducing noise and drag - Raised top fin profile prevents the chain from dropping to the BB shell - BB mounted guides are only compatible with traditional, threaded BB systems
The design of the four arm carbon fiber cranksets that so well identify the Super Record, Record and Chorus groupsets has also found its way into the fantastic Campagnolo Potenza 11 drivetrain, albeit in an aluminum construction. The Potenza crankset is made with both left and right crank arms in hollow forged aluminum to keep weight to a minimum while maintaining the same performance characteristics of its carbon fiber counterparts. Potenza’s four arm spider design makes for one single crankarm for all chainring options thanks to its unified bolt pattern which allows for all three chainring standards 53/39, 52/36 and 50/34 to be built upon the same crankset. Changing between compact and standard with the Potenza groupset is as easy as changing eight bolts and two chainrings. While the 4-arm bolt pattern offers advantages in terms of practicality, the Campy Tech Lab designed it primarily with performance characteristics in mind. The eight bolt pattern with a spider arm design that not only holds the chainring in place by way of the bolt but also supports the chainring and in doing so, increases system rigidity to the point of surpassing its direct competitors in laboratory tests. -Double standardized bolt circle diameter allows for use of standard, mid-compact and compact chainrings -Power-Torque system have drive-side bearing pre-installed. The non-drive bearing comes pre-installed in the bottom bracket cup -Power-Torque Plus system utilizes a self extracting crank bolt for easy disassembly -Requires use of Power-Torque bottom bracket cups -Features Campagnolo X.P.S.S. (eXtreme Performance Shifting System) featuring geometrically optimized chainring teeth. Optimized when mated to a full Campagnolo drivetrain -Power-Torque system uses a single piece axle fixed to the drive-side crank arm which allows for simplicity and a light weight and rigid axle
$165.00 - $180.00
Many top features are packed into the Centaur crankset. The four-arm design allows for independent bolt circles, offering greater stiffness and structural integrity, and also provides additional versatility, as a single crankset is compatible with both standard compact and semi-compact chainrings. Add these features to the first aluminium crankset with an Ultra-Torque axle and the result is a component that is very similar to the top-of-the range part. - Requires use of Ultra-Torque bottom bracket cups-Double standardized bolt circle diameter allows for use of standard, mid-compact and compact chainrings - Ultra-Torque axles couple together in the middle of the BB shell via a Hirth Joint that self centers the crank. This results in a very light weight and stiff system that transfers power to the pedals without power loss - Features Campagnolo X.P.S.S. (eXtreme Performance Shifting System) featuring geometrically optimized chainring teeth. Optimized when mated to a full Campagnolo drivetrain - Ultra-Torque system have both drive and non-drive side bearings pre-installed
Triathlon. Time Trial. Cyclocross. Some disciplines are made for 1x.

Campagnolo is all about drivetrain evolution, and their Chorus Crankset proves it. The full-carbon cranks and 4-arm spider feature a unified bolt pattern that allows for all three chainring standards. This design incorporates an 8-bolt pattern with a spider arm that not only holds the chainring in place by way of the bolt, but also supports the chainring to increase system rigidity. The crank arms and spider are hollow for maximum stiffness and minimal weight. The integrated Ultra-Torque spindle joins the crankset together via a toothed Hirth joint in the center. - Chainring BCD: Campagnolo 146 Asymmetric, Campagnolo 112 Asymmetric
