I don't understand this search stuff.
If you don't want to talk about it, go somewhere else.
I like talking about these kinds of things and I wouldn't get to talk about them if someone didn't ask.
And, how did the stuff get in search, anyway?
By people talking about it.

I recently built up a fixed gear mountain bike.
I had to use 175 cranks for a lot of reasons.
I resisted it.
I worried about pedal strikes, but the extremely high bottom bracket of the mountain bike frame resolved the pedal strike issue.
Anyway, it feels great.
This length of crank actually fits me better, and I find I spin as well or better than at 165 or 170.
