btw, bad things often happen changing rings uphill. It might be theoretically possible to do that if everything is properly adjusted and your technique is good, but why risk having to restart on the hill or causing damage? When you change cogs the chain doesn't have to move as far and the chance of dumping the chain is much smaller.
Well, it was actually adjusted well. I spent 2 hours cleaning and adjusting the drivetrain last weekend. Throwing the chain was actually because of the bent tooth-everytime it came around, it lifted the chain up and in, and off the lower ring. doh!
The hill is in Hopkinton heading toward Upton. The numbers I gave are estimates based on other hills. Mapmyride does not really give a good reading on it, for some reason.
