Just took my good wheels off the old frame and I've got some problems. I'd had it set up SS for awhile, just spaced out the cassette and used one of the cogs. Super bad idea. The cog has eaten into the freehub body after a few months of riding. Only about a millimeter, but the whole thing is of course all seized up now. I think I'm going to have to dremel or hacksaw the cog off, then I'll see how bad the damage to the freehub is. The worst thing that could happen is that I need a new freehub body, but that's way more of a pain in the ass than I wanted. So if you are going to go SS, don't just space out the cassette. You'll just end up ****ing up you're super smooth nice ass ringle hub that you wish you were riding instead of a crappy ball bearing hub that comes stock on the P1.
