I live for the CABE
Picked this up from a caber thinking it was going to be a mead, but with 3” vertical headbadge spacing that is probably not the case. It has a bottom bracket serial number of what looks like A12509. I saw a similar sprocket in the “sprocket compilation” thread listed as a hawthorn but the cranks and bottom bracket don’t look original so it might not be either. Any ideas what it is?
