Pista Stem

I'm looking to get a new stem for my pista. Mine is old and worn. I'm looking for the vintage look, I'm new to road bikes so I have a few questions. As I understand it I need a stem with a quill. I lower it in and tighten it up. Seems simple. What do you guys recommend?

What year is your pista? You need a new fork and headset to run a threaded stem which they havn't been for a while.

I don't know the year. It's in great condition so I think it's pretty new, except for the stem. I don't want to get a new fork since I like the chrome finish. Nitto Tech maybe?

Unless you have an old Reparto Pista (uhh, I think it's Reparto), or unless someone cut threading onto your steerer tube, you're going to need a threadless stem. There's no such thing as a threadless quill stem.

You likely need a threadless stem.

It sounds like you should just go to a shop with your bike and say "I need a new stem for this".

Unless you have a really old school pista, your bike can only take threadless stems, not quill stems. you cannot replace your current threadless stem with a quill stem without buying a new fork and headset.

It's harder to install a threadless stem than a threaded/ quill stem. You can't just lower it in and then tighten it up, because with a threadless stem you are adjusting your headset bearings at the same time. It sounds to me like you'd better let your lbs do it.

I believe my pista does not have threads. I thought that a qwill stem had the round/wedge that tightens everything up. Am I in correct? The bottom pic of the style I'm looking for, but I do have something similar to the pic on the top.

You cannot use a quill stem (the bottom picture) with a bike that takes
a threadless steerer tube/fork (the kind
of set up that goes with the top picture) --they are different
technologies all together. The quill stem requires a headset (the bearings in the steerer tube)
that is threaded into the steerer tube--the stem forms a mechanical connection by wedging
in when you tighten the allen bolt at the top--threadless headsets are pressed rather than threaded
in and have less latitude for height adjustment. They form a mechanical connection by tightening
the allen bolt that threads into the star fangled nut and then by tightening the allen bolts on the
back of the stem. As someone said unless someone retrofits your new threadless headset by cutting
threads into it you cannot use a quill stem--
aight?

Some modern and slightly less-modern track bikes still use threaded forks/headsets. As far as I can tell it's a style thing.

But still, 6 years is a long time in terms of bike technology.

I think the poster was referring to the Pistas of the 1980s.

Yeah... the advances made in inexpensive steel entry-level track bike technology is pretty staggering.
What will they think of next?!
