I’m currently running the stock 34/50t chainrings on my 105 compact cranks. However for the gradients around where I live I seem to constantly be shifting between the chainrings to avoid cross chaining.
Ideally I’d like a outer chainring with less teeth. I think a 46t would be about ideal. But really not sure where to start looking for one, or if it’s even possible? I *think* the BCD is 110mm. So would any 110mm outer chainring work? would I need to replace both outer and inner?
Any advice would be great.The alternative is to go 1×10, but again, not sure if that setup would be supported on a 105 compact crankset.
