Bolt came out of smallest chainring and wedged itself against the bottom bracket, the only way I could free it off was to remove the chainset……Guess what, no chainring removal tools……15 miles from home…….one Pi**ed off Mrs came and collected me from the pub!!!
Best of luck, four years ago for me. It was my third attempt but no-one had forced me into the last time, just did it on my own. Cycling certainly became a lot easier afterwards, still struggle with the weight thing though.
