Campag - Shimano

[Stu Smith]

I need to change the big chain ring from 48 to 50 which is Campag, is it possible to fit Shimano or Sram? As these are so much cheaper than Campag,,

No. Campag use 135mm BCD, while Shimano are 130mm.

Thanks Tim.

Not Shimano, but you should be able to find a Stronglight or TA chainring which will fit.

Be aware that one of the spiders on Campag Ultra Torque is offset by a few mm so only Campag rings will fit. Though a few minutes with a file will open the hole on a non Campag ring by enough to get it on.
