There is little bit of difference in width, yes. There is also the joint that is welded instead of pinned, a little stronger. And I'm not sure if you have the machined brake surface on the regular, but you have it on the XL. This is the rim I was using on my trials bike rear wheel, and I liked it, survived a lot of bashing (the polished one looks gorgeous IMO). I'm 5'10 170lbs though.HuffyMan said:
You might wanna stick with the XLs.
Hope this helps,
