Ionno *shrug* maybe it's partly in the mind too, but it feels LS heavy - could've sworn the RS chainstays are cut-away near the BB join to accept a double/triple which they're not on the left. My frame is the same (I still roll with the double on here, too, yeah!), whether this is actually makes the difference, I don't know - I've not ridden a non-conversion fixed gear.

Either way, wheels/frame/whatever, it's off balance compared to a RS bike, probably just his bike I guess. I know his chainring comes mighty close to the frame on the left side, which wouldn't happen on the right. Surely the dish would be the same, as all he did was flip the wheel around in the drop outs. Again, I dunno - I've ridden it and can only base it off that and what he tells me.
