Threadless Adapter

I posted about this in another thread, but I was just wondering if any of you have any suggestions for a threaded to threadless adapter. I would prefer one that is flush with the headset and does not taper at all, any suggestions?

How about this one: https://www.performancebike.com/shop/...tegory_ID=5230
Edit: One of the pictures shows a taper though. I think I had this at one time in the 1" size and it tapered. Haven't looked at the 1-1/8".

By taper I assume your objecting to the slight gap between the bottom of the adapter and the top of your headset?

You could always use a small headset spacer to fill the gap between stem and the top of the headset. I used a black o-ring.

I ordered this one, no taper and it comes with a shim so it works on 1" and 1 1/8"

The only problem I've had with using headset spacers is creaking. Although, if you used the Cane Creek locking ones, that might not happen.

All threadless stem adapters taper because the quill part that is inserted into the head tube is skinnier than the fat part that the stem clamps onto. The threadless adapter that the Angry NYer linked to is interesting looking. It looks like it uses a shim on the outside, but I am not sure how that works. I can't even see a taper. Hey Angry, do you have to use the shim? Does the stem clamp onto this long shim?

The adapter is designed for use on 1" steerers. I believe that shim is to allow the adapter to work with 1 1/8" steerers.

I have Nashbar's adapter. $10, no taper I noticed, and I'm using a 2.5mm spacer just to bring the stem flush with no visible adapter showing. I used a Sette Aeon stem with Nashbar's 7075 Lite road bars as well, as pictured:

Have you got pulled over by the stem police yet? That spacer thing + adapter + threadless stem is hideous. Sorry, but if I don't tell you people are going to think your name is Fred.

On a similar vein, does anyone know of a quill stem that has a totally removable bolt-on front cap or caps at the handlebar clamp end, similar to those found on threadless stems? I've fitted one of these adaptors and an A head type 120mm stem and as Bellweatherman so fearlessly points out, it looks, well, odd. I'd like to replace it with something a bit shorter, say 90mm to 110mm but don't want to have to remove the tape, brake cables and lever on one side of the bars - by the way, the bars are Ambrosio Campione Del Monde with an engraved 26.4mm centre section. I have nevert seen any quill stems with this arrangement but that doesn't mean they don't, or have never existed! Any ideas chaps?

you realize most of what you see aside from about 2mm of that is the headset. it's a threaded headset and fork. The bike is 20+ years old.

Salsa and Profile quill stems come with removable face plates.

There were a few made but I do not recall the makers (maybe Ritchey). Modolo had one that kind of swung away and was quite nice looking. Cinelli I think later copied the Modolo. I may have the lineage mixed in there, but yes there were removable plate quill stems made.

A little search turned up this 3TTT stem. I also think were some titanium road stems that had removable plates but their look was more of the early MTB stems.

You should be able to find something.

Thanks Guys, all of the options you found for me look as if they will be fine! The TTT model looks awesome. By the way, you've probably noticed I'm new to the forum and haven't quite got the hang of it yet. I'm a bit worried I kind of hi-jacked Wilsuf's thread - should I have started a new one or is it correct to post similar questions on the same thread as everyone's talking about the same thing? If I'm out of line, my sincere apologies Wilsuf. I think this forum's great, beats TV here in England any evening!

Oooh Maidstone! My KEF Reference speakers were made there! Great folks at KEF, too. called for replacement surrounds to rebuild my woofers, and the folks dropped them in the mail for me, no charge the next morning. Customer service isn't dead!

By the way, when it's on the same topic, I see no problem with nudging in to ask a question. Otherwise, you'll just get others complaining that there are "already 3 threads on this same topic."

Thank you, NYer. I think Bell maybe mistook the starnut and headset parts as "spacers" which if they were, would indeed make it look a bit goofy, but with an old school threaded headset, there isn't any way to really compact it any further without just converting to a 1" threadles fork and headset, which would have tripled the cost of my fork upgrade.

Hi Glasswolf, small world! The KEF works is only about a mile and a half from my front door - I regularly pass them on my training ride (should be daily, I know, but work/wife often gets in the way!) Hope you're happy with the sound, they do make VERY good quality gear! Some of my sons' school friends now work there.
Thanks for the advice on asking questions on the same topic, I wouldn't want to upset anyone as all the members I've read so far seem like a good bunch of helpful guys (and girls of course). Best regards to you all.

yeah those KEFs are fantastic. drooled over a set of 104/2 reference speakers for ten years. Finally went and bought a set of them from 1988 or so. One of the final sets to be built before they were discontinued. I adore them. Only things I've found that match them for clarity and presence are the Martin Logan ESLs I bought afterward.

Glad to see you joining in the conversations.

I'd recommend the TTT Motus, even though it's kinda pricey.
