i don't ride either of those hubs (i rode a nashbar rear for a while, and it felt very nice), but the reputation of the iro's is excellent.

it just seems like it doesn't make sense to take a track hub (cup and cone) and subject it to new england winters.

i know people do it, and have no problems, but if you're looking for a high-end hub that can take the abuse, i recommend the phils (i have them on one of my bikes).

they're heavy and expensive, but they'll last.
