Brake and engine troubles commuting on my rental catrike. The disc brakes still seem to be rubbing, even though I thought I had adjusted them properly last time. Argh! So, for half the trip I was pushing against more friction than usual, which my legs did not like. I arrived late at work because of the mechanical pit-stops and my pooped legs. Luckily I work in a building where they manufacture stuff, I should be able to bum some washers and a 5mm alan wrench.
