Camapag' compact chainset 110BCD?

TommyS

Hello all,

Thought I'd post this in beginners as I'm feeling pretty uninformed on the topic.

I've just bought a campag' centaur compact chainset.

I intend to replace the 50 tooth chainring with a 46, as I prefer smaller gears and closer ratios and the current 16tooth (34-50) difference will annoy me to tears.
I digress.....

I assumed the BCD was 110mm and was about to order a Stronglight dural, but then saw an advert saying the Zircal was specifically campag compatible?

I'm now confused.
IS the campag compact BCD not 110mm?

Is this simply a matter of having ramps at differnt places to the dural?

Thanks for any info,

Thomas

Campag compacts are 110, but they have an offset bolt which means you have to buy Campag compatible chainrings, like the Zircal.

Thanks for such a quick reply Nick.

An off set bolt eh?
Pesky campag',

Right Zircal it is then.

Cheers
