I have a really old schwinn 80's frame for my fixed gear, and found a nice set of carbon forks with a headset that looks like it would work, but I was wondering if it is possible to convert. The length of the new stem is 180mm which reaches just to the top of my exsiting headset. will this prodvide enough room for a stem with the new headset or should i look somewhere else?

if the fork steerer tube reaches just to the top of your current headset, you probably don't have enough room for a headset and for the stem to safely clamp onto.

another thing to consider is that the head tube of your bike is probably set up for a 1" headtube, and you'd have to make sure that the fork was also 1". if your bike is a schwinn, it's possible that it uses some crazy non-standard, schwinn-approved headset, which would make it damn near impossible to convert it.

No .. and I wouldn't waste my time or money.

yeah i figured it wasnt enough reach. I did find a nice threaded one that will work that im looking at. I like to waste my money anyhow. Everything is new on the frame except the headset and fork so I figure i might as well update that too untill i get a new frame.
