Hi Alex, cool stuff. quick question:
I have a road bike with Shimano 105 double chainring cranks 53/39 and Sram 9speed 12-13-14-15-17-19-21-23-26. I'm thinking of doing a hilly century and some suggested I change the small chainring 39 to a smaller 30t (available for triple cranks) and then replace the 12t, 14t & 26t cogs of the rear cassette with 25t, 27t & 30t... is that really practical? or do-able at all?
Thanks!
Jason
