There great
i work with someone whos had two sets of those wheels. He really likes them, they are light and stiff for him (he weighs 175). The hubs disassemble easliy for rebuilding, and they all use velocity rims, though i dont know which ones. IMO an excelent wheelset that does not break the bank, however dura ace hubs laced to some nice rims are hard to be beat in almost any situation
