Yeah — I figure the aerodynamics would also help by creating a rear-facing micro vortex creating a bubble of silence behind me for low noise levels while riding.

So i emailed that store and the guy said they are made for a 3/32 chain. Does anyone know if I can find a rear cog for a freewheel that also uses a 1/2 x 1/8 chain? Im thinking it may be easier to get a 3/32 front chainring and a new chain at this point... but id rather not. Thoughts?

Thanks again
