What a difference a day makes in the weather! Joined the east side ride at Tartan Park tonight and did the 3M Afton Loop. Lots of climbing, and several sprints (every time my HR goes above 170bpm).
My chain came off again during one of the sprints, similar to what happened at training camp. Not sure what the deal is. When I jump, the chain comes off the big ring to the outside. Frame flex? Worn-out big ring? Very strange. Anyone have any experience with this?
