Thanks for clarifying striknein . Yeah i've tampered with a roadie I had understood how the threadless system works .

A bit off topic , but I found this (link:http://www.iminusd.bigcartel.com/pro...on-zs3-headset) as it states it's the only integrated headset that can fit the 725 / 727tr frames . A few other forum members said I only needed a threadless headset .

Out of curiosity would this headset work ? (link:http://www.amazon.com/Aheadset-Zero-.../dp/B003HGPQPS)
