The ultimate must the complete set of Campagnolo tools in the wooden box. So far I've got:
set of 3 headset/bottom bracket spanners
6mm allen/8mm socket tool
pedal dustcap spanner
crown race remover
cone spanners
crown race fitting tool
crank extractor
crank bolt spanner
5mm allen key
dropout tools
pedal cone spanner
chainring peg spanner
On the wanted list are the headset cup remover and the dishing tool to replace the non-Campag ones I've got:
Minoura folding dishing tool - a bit bendy and flexible
Cyclus headset remover - made for both 1 inch and 1 1/8 inch. Awkward to use for 1 inch headsets.
Re seatpin spanner,
Yeah I use the rear bolt for final tightening and the front for angle adjustment.
To adjust the angle, I loosen the rear bolt just enough so that the front is also loose, loose enough that it doesn't need any force to turn.
With the open end of the spanner, I can reach the front bolt from the back of the saddle between the rails (over the rear bolt), and because the bolt is loose it doesn't matter if the spanner is not at 90 degrees to the bolt. You could even use your fingers if you can't reach it with a tool.
I haven't used a ratcheting spanner for this but I suspect it might not work for the front bolt. The ones I've seen only have the ring shape and is completely flat (looking from the side). This would make awkward for the front bolt.
