So changing the chain rings seems to be the way to go. It looks like the front derailleur (Tiagra) can only handle a 16T gap so I'll need to change both rings. Can I use any 10 speed chains that have a 90mm BCD / 30T and a 120mm BCD / 46T? Any recommendations?
Typically, I can't seem to find any in stock, and wondering if I'm better just buying a crankset and taking the rings off.
