My question is will a 2007 SG hub work, are they  different to a 2012 SG hub in width. I've been told I have to replace the bearings but just want to know if they are different at all otherthan the bearings.

I can't answer your question specifically, but I can let you know what I found when I tried to fit different model 21" front wheels to my 07 wide glide last year. First I tried to fit an 07 softail front wheel, bearing size was 3/4, mine was 1", no big deal I thought, wrong, not only are the bearings different, the bearing seat is machined at a different depth. Sold it and got my hands on a 05 wide glide rim, same thing 3/4 bearings with a different seat depth. This time I got the hub machined so I could use the same spacers and bearings in both wheels, I wanted to keep my stock old rim in case I damaged the smooth rim that I preferred, and only have to use one set of spacers & axle for both wheels. It may not be the case for what you want to do, but you may run across something similar.

Quality bearings from a serious bearing supply place solved my bearing issues.

I used some wheel spacers from 07 and some from ABS era 2012?, 2014? I can't remember, but it all bolted up fine, Wheels are straight, fixed in place and rides true. I hope this helps. Im reliably informed that 07 and 08 are the only years using 1" axles. It does make it hard but not impossible.

Oh and 25mm bearings will not fit 1" axles.

I want to try to get a 190 back bag in as I read that a 200 will not fit.

I am interetsed to see how you get on Steve.

What size rear are you fitting.

Cheers

The spokes on the 19" are pretty ordinary anyway.

Did you end up using the 2012 hubs amd spacers etc.

What width are the WG rims and what rear bag did you go with.

keen to know as I am oing the research as well.

Cheers.

SG is 4.5 not sure what the WG is that you used.

I assume you used the standard rear hub so no spacing issues.

thanks

just not sure about clearances.
