Kcnc’s Ultra Torque chainring bolt sets are an inexpensive replacement option for worn or damaged stock bolts. Additionally, they may be purchased as an upgrade for color tuning a Campagnolo crankset. These chainring bolts are expertly machined from high quality 7075 aluminum and attractively finished in six color options.
Please note that these chainring bolts have limited compatibility, due to Campagnolo’s continually evolving standards. Kcnc’s Campagnolo Chainring Bolt Set is compatible only with pre-2012 Ultra Torque cranksets. Please contact us before ordering if you are unsure that these chainring bolts will work for you.
To avoid accidental loosening, we recommend that Kcnc Campagnolo chainring bolts be installed with a medium-strength threadlock compound. In the absence of threadlocker, light grease may be used. Using a torque wrench, tighten each chainring bolt to a maximum of 7 Nm (62 in-lbs).
