Hello all,
Now that I'm putting a road bike together, I'd like to know which cassette ratio would best serve me for flat terrain, mostly short(ish) rides at a time (typically, two or three 10-15 mile rides a day).
I like to put on speed and mash
occasionally on those short rides, I already know I want to have a regular 53x39 double crank so I can have a 53-11 ratio available for the occasional mashing, but I'm trying to figure out which cassette would be best to go along with the regular crankset: 11-25, 11-26, 11-28 or 11-32 (for flat terrain). I'm wondering if an 11-32 cassette would be pretty much useless for me since I
never come across climbs or anything resembling one, unfortunately (well, maybe some garage exit here and there

).
Should I go with an 11-25 instead, for smoother gearing?
I'm also going with a 172.5mm (instead of a 170mm), since the owner of the LBS suggested that for me (for short rides and putting on more power).
Any advice or suggestions much appreciated!
