Some years ago I found an excellent step by step guide to setting up your gears and getting them indexed somewhere on the internet, which I used a few times and found just following the instructions carefully made this a short and easy job with really satisfactory results.
I got a new bike recently which was supplied quite poorly set up by the mail order place I bought it through. I sorted the gears (2x10 Tiagra) out myself a few weeks ago, but couldn't find that guide and found myself flicking between various website and youtube tutorials. I got them running properly eventually but it seemed more annoyingly fiddly than I remember from last time I needed to re-set up the gears on some bike.
I've since ridden a few hundred kms on the bike and I guess the cables have stretched - it wasn't shifting into the biggest cog at the back last ride, the front mech was rubbing in some chainlines etc etc, all the normal little annoyances of not quite perfectly set up gears. So before I dissappear into the garage for several hours - does anyone have a favourite step by step guide they've found works really well?
