smallest you can get for Campag 135BCD is 39 tooth, so no 38 I'm afraid. Don't get confused with Shimano fit 130BCD spiders, they are different pattern rings.LukeFRC":1w8z92w1 said:I'll check but think I've got a 52 from my old bike that will work - thinking I can probably use the chain rings from the old bike and run 52-38-30 ?
I need to look at the condition of the 30 and 50 on there currently the 40 is shot.
that's how the chainset came set up. You don't have to stick with that, you can separate the rings and fit anything that fits the spider.On them they are labeled "50-40" and "40-30" - what does that mean is that something about how it shifts or something?
