I can't believe I still have these. Don't be scared. 4.56 isn't too low.
$125 shipped.

I have been thinking about getting these since you posted but worried I will not like the rpms on the highway. With my 29" tall tire that would put me at roughly 2,600rpm at 70mph which is about 600rpm higher than my current 3.73 gears. If only it wasn't a daily driver.......
