Brought the bike in this morning as planned, and realised (only about half-way through the commute) that my front mech is goosed - most likely seized up or lacking any cable tension after weeks of neglect. The chain is stuck on the big ring at the front, so, unless I can sort it out later, I don't think I'll be getting home on it as there is no way on this earth that I'm getting up the hill to home in the big ring.
If push come comes to shove, I could manually shift the chain down to the smaller ring, but I reckon it will rub badly on the mech unless I free it off somehow.
What a pain in the arse. I had taken the bike out for a brief check of tyre pressures, brakes, lube etc. last night, but we had visistors round, so it was a very quick once-over.
Ah well, no -one ever said it was going to be easy getting back into it, but I had assumed it would be the man, not the machine, that would provie to be the weak link.
