if you think the stock hubs dont suck, please take a gander at the kilo thread. i stripped mine real quick. my friend stripped his in a matter of weeks. i didnt notice it til i replaced the front wheel but the hub grinds like crazy when i spin the wheel.
dont get me wrong, at the 350 price point i wasnt expecting durable, and the hubs are the only thing i have to complain about so overall im pleased with the bike. it would be nice to not have had to replace the rear wheel so quickly tho.
