Doesn't look like there are removable spacers on the current setup...the plan was to get some to put on the left side of the hub which would effectively slide the rear wheel to the right of the axle so that the installed freewheel would be closer to the drive-side chain stay. With this kind of hub the spacer I'd imagine would be of a narrower sort that I've seen online for free hubs, is there any kind in particular to buy or any that would fit that bolt?
