Last night, I switched out the 44 tooth biopace middle chainring for the 38 tooth round one. I took it out for a test ride, but it wouldn’t shift onto the granny. So, I looked in my secret bicycle repair manual and I learned how to adjust my front derailleur. Now the Trek shifts nicely through all the gears, and I have a nice, easy mid-range for commuting slowly enough as not to need a shower when I get to work.

Perfect.
