A quick question.
I have some spoke wrenches from old OEM Yamaha tool kits.
They are named 8, 9 and 10 - the higher the number, the smaller the wrench.
Does any of you know what that corresponds to in mm (and why Yamaha are using these numbers instead of just mm or inch)?
Size 9 seems to be very close to 5.8 mm.
I've spend time on Google without getting any wiser...
Please enlighten me.
