During yesterdays ride I found it difficult to engage my top gear and also experienced a noisy front shifter, so today I decided to make a few adjustments. I started out by standing the bike on the seat and handle bars, but this made it difficult to access the limit screws and generally see what I was doing. In the end I resorted to stringing the bike up from the rafters in the garage; much better to see what I was doing but a little unstable. How do you manage these sorts of repairs and adjustments without buying a proper workshop stand?
