Larger rear sprocket

[PowerDubs_imp]

I know several people have mentioned gearing for lower RPM...but I find my 14 plenty low enough rpm on the highway, even at speed.

I'm looking to give it a little more spunk. It is very popular on many other bikes to drop the front sprocket a tooth which is usually equal to going up 2-3 in the rear. This is usually done because the cost is less, and the work involved less as well.

I am not really a fan of that in the long run because the decreased radius makes for accelerated chain wear. IMO it is better to go larger on the rear sprocket but that sometimes involves a new longer chain as well.

Has anyone done either? Thoughts? Links to threads?

Thanks.
