How to Remove a Campagnolo Record Crank
(Jupiterimages/ Images)

A crank is the heart of a bicycle’s drive train. The crank includes the crank arms, chain rings and pedals. Applying force to the pedals causes the crank and chain to rotate. The chain then turns the rear wheel, propelling the bicycle forward. Unlike previous models, the Campagnolo Record Ultra-Torque crank forgoes the use of separate crank bolts to hold the crank in place. A single bolt passes through the right, drive-side of the crank, mating the geared spindles that are attached to each end of the crank.

Skill level:

Things you need

  • Flathead screwdriver

  1. 1

    Locate the bearing retaining clip on the right, drive-side bearing cup. The bearings cup is fitted between the crank and the side of the frame.

  2. 2

    Insert a narrow flathead screwdriver under the raised end of the clip. Use the screwdriver to pry the clip free of the bearing cup. Set the clip aside.

  3. 3

    Fit an extension onto a socket wrench. Fit a 10mm bit onto the extension.

  4. 4

    Use the assembled socket wrench to loosen the bolt at the centre of the right, drive-side Campagnolo Record crank. The bolt turns counter-clockwise to loosen.

  5. 5

    Separate the right, drive-side crank arm from the bicycle. Separate the left, non-drive side crank arm from the bicycle.
