I change it routinely. Both bikes have those silly QRs on the seat posts, might as well use 'em. I even mark the posts for quickly finding the right height. I ride platform pedals with whatever shoes I feel like wearing that day. Even a 1/4" adjustment helps. Reminds me, I need to adjust it for my new Merrell cycling shoes. Just got 'em this week, got a little soreness in the left hip. The Merrell soles are less flexible and just slightly than the Montrail hiking shoes I usually wear.
