"---i didnt realize a 1" threadless headset meant that was the size stem the bike took" .. No... it means the diameter of the steering tube... not the diameter of the stem clamp?. A stem for 1 inch steering tube in quill are 2.22 mms diameter (or so) but untill now I have no idea if u really have integrated headset or not u know... Threadless could be integrated or not.. so at least my self IM quite lost wiith your descriptions.

The thing Is that im quite unclear too.. pista? wich pista? Bianchi pista? fiji pista???? Olmo pista? Ridley pista? colnago pista********** Would u start saying exaclty what bike do u have???

What I would do is go to the net... look for the bike u have and paste the link in here so we sould figure it what do u have... or... take a picture of it and post it (go to advance when replying then down ull fine a bottom saying attachments)

I understant that nobody tought u about this stuff.. I was confused too when I came back to cycling after 15 years and the stuff has changed a lot but I catched up in a few weeks... Sorry us for be so technicals sometimes but w/o some data is hard to help u know..
