Fettled a bunch of things and then decided it was time to swap out my mech hanger. It's been straightened a bunch of times and each time it has weakened it, and makes indexing gears for smooth changes impossible.
So, I took the old hanger off, was making ready to put the replacement one on, and, er, found out the 'spare' hanger I got is for the wrong frame 😳
So I've put the old one back on and ordered the right hanger in the post.
Better to find out from home than on a roadside with a snapped one I suppose...
