|Will threaded fork work with threadless stem/headset?||timwat|
Jan 21, 2004 4:44 AM
|I'm thinking of converting my 1" threaded setup to 1" threadless to get my bars down a little lower. Can I just replace the headset and clamp the new stem on the threaded part of my current fork or will I have to buy a new fork too?
Thanks in advance,

|You need to rethink this whole thing. Maybe you only need a stem with a different rise,assuming your quill stem is as low as it will go in the steerer. Your current fork is not long enough,unless there is a lot of spacers between the two top nuts,which is not typical. You neeed fork,HS and stem.|

I purchased a stem converter for my threaded fork so I could run a threadless stem...if your not into grams could be a cost savings solution....the converter inserts into your current 1" threaded fork but allows you to clamp 1 1/8 threadless stem...saves big bucks and looks/performs just fine.

|Here's my current set-up. The bar height seems fine for normal riding, but I would like to use clip-on aerobars for some time trials. When I put the bars on they feel too high to offer much advantage. I thought of buying an integrated aerobar/stem combo, like the Cinelli Angel, which seems to have lower arm rests. But for the price one of those I think I could get a new fork, headset, stem(could use a slightly shorter one anyway), and maybe some ergo bars, and switch to threadless then use my clip-ons. It looks like the nut on the current set-up makes the stem at least an inch higher than threadless would be. Also, I haven't really been able to find a quill stem with more drop than the current one. Maybe I just need to look more for a stem?|

|It looks to me like you have a spacer between your upper headset race and the locknut. If that's the case, you could lower your bar by removing the spacer provided you cut the fork's steerer tube by an equal amount.|

|of your headset looks like its responsible for a little extra height. What kind of headset is it?
I believe the Ultegra threaded headsets have a lower stack height.
You have a pretty unique problem. Most want the bars to get higher, not lower.
If you do decide to convert to threadless, then you need a new fork, headset and stem. FYI, most threadless stems are 80 degree (I think Ritchey makes a 73 degree threadless). The threaded stem you have on there now looks like its a 73 degree.

|Getting a convertor would seem to be the answer. I tried to get hold of a decent quill stem last year and they are increasingly rare - which is a real pisser for me because I've got three frames that need them :-|
I'm more or less resigned to trying to find a frame that will replicate the ride of my Reynolds 631 steel frame - a tall order in my opion.

|Whenever I see one for a reasonable price on Ebay or an LBS, I buy it. IMHO, it's still the best looking stem every made.|

|All eight of the bikes in my family use quill stems, and you're right--they're getting harder to find. But it's not a thing you have to replace very often, so we're pretty well set up.
Probably the easiest way to lower the bars (not necessarily a good idea, but that's another debate) would be to swap stems. You might look at www.rivbike.com to see if they have anything that will do it.

|No, your fork will not work if you convert it. A threadless setup needs a fork that extends well above the top of the headset, and that's not possible with your current fork.
As other suggested, you can use a quill to threadless adapter, or you can replace the fork.

1. The steerer tube on your current threaded fork is too short to just swap headset and stem. You won't have enough steerer rising above the headset to safely clamp the threadless stem onto.
2. You have nearly an inch of unneeded spacers (I can see at least two in the photo - the lower one is darker grey, the upper one or possibly two are silver) between the top nut and the lock ring (the first ring above the headset - it has slots cut in it for a hook wrench to fit into). You can remove the stem, top nut, and spacers, then measure and cut the steer tube so the top nut will tighten directly onto the lock ring without spacers between them. You'll need to leave about 1/2" of threads above the lock ring. If you don't cut enough off your headset will loosen every time you ride, if you cut too much the top nut won't have enough threads to tighten properly. Remember, remember, remember: "Measure twice, cut once!"
3. Your stem is quite thick - I have seen old Cinellis that have half the diameter that your stem has. You may be able to find a quill that will allow more of it to be inserted before the bottom of the stem hits the top nut. 'Course, it probably won't have a removeable faceplate, which is a serious factor to consider!
Good luck - that's a beauty you've got there!

|Cinelli makes one.I paid about $15 for it a few years ago. Allows you to use a 1" or 1 1/8 " threadless stem.|| |
