Front wheel offset.

[gazza]

G,Day. I purchased a Triumph T120R from the USA, an ex racing bike. It has a Yamaha front wheel single disk brake. Year unknown but the best I can find out is it's a 1981 or 1982, by the calliper repair kit ( not the best way to find it's year, but the best I can do). COULD ANY ONE HELP ME PLEASE, I am having the front wheel rebuilt new rims and stainless steel spokes. The wheel builder asked me the offset of the wheel, just after I cut all the spokes and removed the hub for polishing. Could some one please measure the offset from the outer face of the disk to the mid point of the wheel rim. Thank you for reading this request, if any one has a better way to age this front wheel please let me know any assistance is very much appreciated. Thank you. Gazza

That is a 1972 XS2 hub/spool. There is no offset. The rim is centered on the hub/spool.
Hopefully you have the correct disk carrier and forks. All of it is 1 year only.

Also the axle and fork trees.
