TA Specialite Nerius chainring

The TA Specialite Nerius 10-speed chainrings are designed for Campagnolo Ultra Torque 10-speed cranksets and feature the appropriate mounting for the Ultra Torque crank arm. These chainrings are not compatible with other cranksets

The 110mm bolt circle is the Campagnolo road bike bolt circle for cranksets with a compact gear ratio. The smallest chainring that can be fitted is a 34-tooth model, whilst the largest can accommodate up to 53 teeth. This bolt pattern is also used by other manufacturers; however, the TA Nerius chainrings have special drill holes for mounting on the 10-speed Ultra Torque cranks and are therefore not compatible with ‘standard’ 110mm crank arms.

Compatible with Campagnolo Ultra Torque cranks

Please note that the gap between individual chainrings should not exceed 14 teeth. Otherwise, you will have to accept compromises in shifting performance.
