Being relatively new to all this I have some questions:
1. How much does wheel diameter affect gearing choices?
2. How much does crank length affect gearing choices? (I run 170's, which I'm learning is not the norm for SS racers; but I'm not terribly big and neither is my bike.)
3. How often do the rest of you change cogs (depending on terrain, mood, et al)? Example: right now I race on a 26" wheeled Monocog and for short-track season I'm running a 32 x 19 (it's a course with a lot of moguls and bumps). For 'cross season I usually swap to a 32 x 18 for the flatter, drier course; and later in the fall when it gets good and muddy I will swap to a 32 x 20. Since I am using Surly cassette cogs it is quicker and easier for me to just swap the rear cog, and the length of the track slots gives me plenty of room to adjust chain tension without worrying about how many links I have/need.
I'd like to know what other riders use and if their choice of wheel size affects their gearing choice very much. Thanks --bh
