I've got a blb track pista crankset laying around and I want to convert my crosscheck to single chainring. Can I use that crank?
The chainring will be for a single speed chain which is too wide for a cassette. You could find a 3/32” chainring which would work up to 8 speed.
Worth checking if the existing chainring is 1/8" or 3/32" before buying a new one - 1/8" is the more common track width, but plenty of single speed setups come with 3/32" as standard. It should say on the chainring.
Don't worry about formatting, just type in the text and we'll take care of making sense of it. We will auto-convert links, and if you put asterisks around words we will make them bold.
