SRAM Omnium crankset

Older goldtecs were made with a 45mm chainline, but the ones they are producing currently (since they started doing them with the raw silver finish) are 42.5mm, so should work with your omniums without any issues.

Goldtec have been calling it 42.5mm for some time and were notorious for catching people out - it's mentioned on threads here more than once. My older ones are definitely 45mm.

Do you have any new ones yourself, or are you going by the web site alone?
