after you buy that, you'll just need a stem, handlebar and saddle, essentially. miche is good quality stuff too. i use miche hubs on my bikes.

in theory, 36 spokes build a slightly stiffer wheel that will keep in true longer, since each spoke does less work. in practice, the difference between 32 and 36 is pretty negligible, especially on a rim like the openpro. it might make a bigger difference on a crappy rim.
