ULTRA TORQUE Super Record™ CRANKS 12x2 have been updated for the 12-speed system. The new chainrings are optimised for use with a narrower chain and the double ramps ensure an instant response when shifting. The design has also been changed, achieving better aerodynamic values. Of course, the time-tested system of joining the two half-axles with a single bolt (the Ultra Torque system) has been retained.

The cranks are traditionally made of carbon fibre. To achieve the lowest possible weight they are hollow. The carbon cranks are fitted with titanium half-axles joined by a titanium bolt. The half-axles include ceramic bearingsCULT with incredibly low rolling resistance. The chainrings are also new, with modified ramps for faster shifting – they are newly not attached to each other but bolted directly to the cranks. This integrated chainring mounting allows every combination of chainrings produced to be fitted to a single type of crank. The chainrings are tightened to the cranks with light duralumin bolts. The cranks are offered in lengths of 165/170/172.5/175mm and in chainring combinations 53-39/52-36/50-34.

The Q-factor of the new cranks is 145.5mm – the cranks are compatible with bikes with classic rim brakes as well as bikes with disc brakes.

All Campagnolo Ultra-Torque cranks are fitted with two industrial bearings. Each bearing is pressed onto one of the half-axles. The bearings are offered in 3 different versions.

Recommendation: to be able to fit the cranks into the frame, you need to choose the appropriate PRESS-FIT bottom bracket cups or adapters that match the specification of the frame they will be fitted to. You will find the complete range here.
