yeah, a different gear ratio will definitely change how the chain meets up at the end, you might actually end up finding the perfect SS gearing for that bike, which would allow you to forgo the singleator altogether, which would be really hot. it looks to me like you could take at least two links out of that chain (especially with the singlator in the pull down position), but i've never really worked with a singlator before, so i'm not familiar with it's particulars...anyway, i like the way that bike looks.

it's so frustrating when you're less than half a link away from getting the chain perfect...

oh, quick question for anyone out there: why do people run easy gear ratios on MTB singlespeeds? shouldn't i be able to run a 44/16 on a MTB? i bet it probably has something to do with frame geometry and wheel size...
