From the IE, think its 20mm. Need the bit for the forks too, the threaded insert. I have posted in the wanted section, just thought I would ask here too. Ian
Ian, the later IE 20mm spindle requires a nut to secure, no thread insert, I have a front spindle with nut if you want it. Wayne EDIT: or that should read idiot! the later IE spindle is of course 25mm not 20mm:Shamefullyembarrased:
no it won't fit earlier forks, my apologies I leapt into the discussion too quickly without checking, I have the IE forks and the associated 25mm spindle.
I have the insert, found it tonight while working on my 400. PM me if you want it, i will check the size in the mean time.
