Chain Locking up
This happened to me about 2 weeks ago and my GF today. I am wondering if there is a way of dealing with this.
While riding at low speed getting ready to stop my chain locked up and with my weight all over the place I toppled over. The chain on the FD jumped from the smallest to middle cog (Tiagra triple) and jammed up my chain. The deraileur was in alignment. My GF's chain locked today ( could have been other things on hers I am not sure yet and am not sure I will ever be sure what caused it)
In my case I have 2 guesses. Option 1 the deraileur was not enough in alignment and frame flex ( I was standing and pedaling uphill) cause the deraileur to hit the chain. Option 2 this is just the nature of ramped cogs and it may happen from time to time.
Anyone have any ideas for dealing with this?
