Reminds me of a visit to a CO Springs bike shop, me being a SC mountain biker at the time. "So, how do you guys keep these bikes so clean?"
gets blanks look and hears small wheels turning
"Sometimes we blow them off with an air hose."
That just doesn't work if you dip your bike in mud every other ride. I was in the habit of lubing up before every ride - including the clipless pedals.
