• Hi Chris, yes I'd be interested in either of those if they're French threaded, though I guess it won't matter for the one that needs a Helicoil. As long as it's not going to leave you with orphaned right side cranks. Agree about the cold!

  • If it helps, I just bought a drive side 49d crank that was sold as french threaded and marked as such on the rear of the crank, but when I got it my British threaded pedal screwed right in no problem, didn't even need any convincing to go in. So I think you may be able to do this the other way around, brit thread to french pedal. Seems solidwhen ridden. My guess is the threads are similar enough and the alloy is soft enough/pedal steel hard enough that it just cuts a thread. +Having said that, when I check it it doesn't look like a new thread has been cut so maybe my crank had been rethreaded in then past?)

    Nah, 14mm into 9/16" (14.3mm) is too sloppy to be usable. The only reason you can recut French 1.25mm pitch threads to British 1.27mm pitch is that the diameter difference is enough to make the profiles overlap for long enough to get through a crank.
