OK so I have a road bike with 52/42 chainring, Square Taper BB and working with a 12-25 cassette.
I find that the 42 is not adequate for some inclines. So I've been thinking:
- Replace the 42 for a 39t (simplest)
- Replace the entire crankset for a compact crank like 50/36.
- If I do the above, should I also get new BB or get a square taper crankset that will be a direct fit?
What say you?
