english pedal threads on an old Gran Sport crankset?
Anyone know enough about vintage campy GS cranksets to tell me if I can thread them with new(er) pedals? I love spd's, and the Christophe toe straps are killing my feet. The 3-arm Gran Sport is reasonably rare, so rethreading is not an option.
Thanks |
I thought pedal spindles were hardened. If so, re-threading them with common tools would be difficult.
I've never tried it, though. |
I think you are pretty safe. French pedal threads are another matter ...
I think the biggest Italian - BSC thread mismatch problems arose with freewheels on aluminum hubs. |
The pedals of your bike will be the common "English" threading. The right pedal is a right-hand threading and the left pedal is a left-hand threading. On older steel cottered cranks, inspect often for cracking.

Mike- I meant rethread the crankset. (btw, I agree pedal spindles would be dificult to rethread, as I have actualy used them to straighten threads on old cranks)
Calvin- the Campagnolo Gran Sport crankset (circa 1973) is a cotterless setup, but thanks for the advice. JohnE- Yeah, I made the mistake of accidentaly threading standard pedals onto the old Solida crankset on my Astra. I got them screwed pretty well snug before remembering it was french threaded. I didnt want to repeat my mistake with my "nice" bike. thanks all! |
There are two kinds of "English" threading, one of them is the same as the threading we use now on all bikes, so try it.
