I've often been told to look upon a good tool as an investment...
right to left
30/32mm spanner - for threaded headsets
15mm ratchet spanner - for track nuts
Cyclo pedal spanner - for, you guessed it, pedals
backnut tool - for holding the nut on chainset bolts
24mm spanner - for the campagnolo bottom bracket tool
If you wish to use this photo for your blog, etc that is fine. Please use an attribution of 'zzpza' and link back to this page. A comment here with a link to where you have used it would be nice too. :)
