Back into my daily commute routine after missing several days last week due to a cold and work. I had taken one of my bikes to the shop to get the rear wheel trued and tensioned and picked it up over the weekend, so I'm riding it again this week. Yesterday, after leaving for work I noticed that my position felt off on the bike. After a mile or so, I realized that the mechanic must have test-ridden my bike and moved the saddle. So I had to ride 22 miles to work and back with my saddle in the wrong position. When I got home and checked it, the saddle was about 2 cm too low. I'm lucky that I didn't injure my knees. Note to self: measure saddle after picking up bike from the shop.
