Went away for the Bank Holiday weekend, somewhere between Llanymynech and Lake Vyrnwy. Planned on an 80 miler until I had an 'off', which in turn ended up in turning around and heading back. Still managed 52 miles, though, so not all bad.
Chain jammed uphill due to a problematic rear shifter (see below**) and ended up falling onto the drive side of my bike. Luckily, I managed to get across to the other side of a narrow country lane and fall onto grass, but I think the drive side bar end and the RD took the brunt of the impact.
How to check for (aluminium frame) bar alignment, frame alignment (the bike seems OK but I'd like to check the DS chainstay) and how can I align the RD properly? I bent the hanger back out as visually straight as possible on the fly, but it's either that that's out or the RD or RD cage is bent. I just can't see if it needs tweaking without visually inspecting an identical 5700 RD. The cages aren't straight like they used to be, so it's hard to tell what should have a curve in it and what shouldn't.
TIA.
**The shifter problem arose when installing new cables. I couldn't seem to get the throw right when shifting up and down the cassette. I lifted the hood back and looked at the internals, that's when I noticed a little triangle of silver, grey Aluminium move and fall out onto the floor. I couldn't find said piece of Alu and can't for the life of me see where the missing piece has come from.
