Crank Repairs and Modifications

Pedal Thread Repairs

If you have stripped, damaged and crooked pedal threads these can usually be repaired by installing a new thread insert. We then mill the surrounding area to ensure a perfect pedal fit.

We can repair the pedal thread on carbon cranks if the original metal insert is still bonded to the carbon.

Unlike some of our competitors, we ensure the accuracy of the new thread using a precision milling machine and custom made jigs.

Crank Shortening

Please see the crank shortening page for details.

Tandem Cranks

Crank Repairs and ModificationsSend us your standard cranks (2 right-hand ones and 1 left-hand one). We will reverse-thread them to turn them into tandem crossover cranks. We can also shorten them at the same time at no extra cost.

Other modifications

Please contact Patrick to discuss any other modifications you may require.

Note: we don’t straighten bent cranks or repair damaged bottom-bracket tapers.

Your guarantee

If we have doubts about the suitability of your cranks, we will contact you before proceeding. All work is carried out on special jigs and remains true to the bottom-bracket axle (even if your crank is bent)


We won’t work on your cranks unless you accept our terms and conditions.
