  • I've knackered the threads on a set of fairly new cranks (not sure how, the pedal just came out after a few hundred miles). Any recommendations for somewhere to sort them out? I'm thinking they'll need drilling out and a new thread inserting. South London preferable but happy to post if needs be.

  • not sure how

    Nearly always incorrect (too little) installation torque

  • You can get a helicoil repair -new threads cut to a larger size (usually 5/8ths x 20) and a threaded bushing with an interior 9/16th x 20 thread fitted.
    This is a dead common repair any proper bike (repair) shop will do it.
    Cranks need to be solid aluminium alloy (or steel 😉)

  • I assume you have you tried threading the pedal from the reverse side of the crank to clean the threads out then refitting on the correct side? Might work if the threads aren't too far gone

  • A mate had his cranks done at Bom Velo in Herne Hill (they’re also in west Norwood), and was pleased with them.
