My current rig utilizes the Nashbar flavored Dimension hubs. The rear dimension hubs come spaced at 120 with a bearing preload nut and a serrated nut to grab the inside of the frame. Two spacers were added between the two mentioned nuts and on each side of the hub. This brought the spacing up to ~130mm. The Dimension axel is not a long like Formula, and there are two unused threads within the track nut when the wheel is mounted in the frame. I've ridden off road many times using this setup, and the bike has been raced 2 times also. The confidence level is very high for this setup, and I have no fear of a nut coming loose.
The biggest loss is the inability to add a chain tensioner due to the lack of axle length. On the upside, my
"wheel walking" has improved. Now there is no need for a chain tensioner.
I figure the hollow axle will fail in shear before any other problems arise.
