So I've certainly bit off more than I can chew with the chainring. 50t with 12-25t on the back is too high geared. I mean it's great for mild hills and on the level, but any kind of actual real incline and I'm toast. I'm deciding between 38, 40 or 42t. Probably gonna go with a 40t. But can't seem to find anything that isn't crazy high priced, in 130mm BCD, that isn't in China. Any ideas?
