I use the 38 with 1 0r 2 when I go for medium speed due to busy streets, traffic lights etc. But when I get an open long avenue or similar, I use the 48 with 1 or 2. Then feel like I could get more speed and stronger pedaling and the bike does not let me. So I guess I may need a bigger crank and a different cassete, waht would be a step further of what I have now?
best regards
So you are spinning out on the 48/11? First of all, you are a monster, that is a hard gear! If you are not spinning it out (i.e cadence around say 100 rpm in that gear), then you need more strength.
If your derailleurs have the capacity, you should be able to replace the big chainwheel with a 52, or replace the whole crank with maybe a 52/42/30.
