Hello 1st time posting here, I just put together some alloy rims and spokes, does anyone know the offset for the rear wheel or where to get the specs.

Hi there, welcome to the forum,

I'm not sure for the 76 (is it disc or drum brake?) The measurements I had for the offset for my rear wheel (72 T120R) were 2.0" (50mm) taken from the L/H side measured from the edge of the brake drum. As I said I'm not sure if the later models are the same.

Thanks Webby, mines a 76 t140v disc brake , I have wm4 (2.50) 18'' rim, the spokes are a really good fit there appears to be around 1/2" offset to the chain side.

Hi Whatsthat,
In that case, I don't think my measurements will be of much use to you. My rear is a wm3. If no one can come up with a measurement (I'm sure someone out there can) You could fit the wheel to the bike with all the spacers etc. and then adjust the offset as required.

Good Luck

I thought I may like to see that page,re the offset. I measured all that up and that is very close to the untrued dimension, canny George will be able to work with that, thats a very complicated hub set up also, being in three pieces I think it will need to be trued with the disc and sprocket in place..chances are once trued if you took the bolts out again it would never go back together.
