I'm trying to decide whether to change the outer ring on my compact chainset from a 50 to a 48 tooth
Reason being that there aint many flat sections were i ride here in south wales and find that its very rare i use the 50/12 or 50/13 combination.
so was wondering whether to switch the outer ring to a 48 and would that help in using the lower two cogs or am i just better off cycling in the 50/15 - 50/17 rings and not use the bottom to of the rear cassette.
Thoughts??
