does this exist? id like to use this handlebar, and id like to stay 1" threadless. thanks

If you mean a 1" stem that fits 31.8mm handlebars - I haven't seen any. 1 1/8" is the current standard. What exactly are you trying to do here? How does the bike have only a 1" steerer?

thomson 31.8 stem with thomson 1 1/8 to 1 inch shim. i use it this way and its fine...

solbrothers

here is the handlebar.

btw, thanks for the quick responses!

Is the stem a goose-neck quill-type? As in one you tighten/loosed by turning the center bolt? One piece deal that is shaped like an upside-down letter 'L'? It would help if there is a photo of the set-up. When you say threadless, I am confused. The standard is not 1". Please describe this animal fully.

the motobecane messenger has a "threaded" quill stem. NOT threadless. i am almost positive that there is no threaded quill stem in production that is 31.8. here are your options....

1. get new bars that fit your current stem. (probably 25.4 or 26.0, have your LBS measure or ask bikesdirect)

2. convert to threadless. this means you will need to get a 1" threadless headset, 1" threadless fork, 1 1/8" threadless stem w/ 31.8 clamp and a shim.

it seems like youre best off exchanging those bars for ones that will fit

fatigoworld

the bike is here

it is a quill stem, which i addressed above...

solbrothers

yeah, looks like imma buy another bar.



here is teh bike btw

fatigoworld

measure first! most risers bars are 25.4 or 31.8 (actually i cant think of any that are 26.0). sooo....

if your stem is 25.4 then just get a 25.4 riser bar.

if your stem is 26.0, you can buy a shim to use a 25.4 bar with your stem.

the shim can be found here....

A Stem-Converter made by Profile Designs or Dimension (Zoom makes one as well - but no one seems to have them) that is 1" x 1 1/8" will take a stock 1 x 1/8" stem which will fit your new 31.8mm bars. The 1" end drops into the head tube on your bike and the top end is 1 x 1/8th" that accepts the standard stems available. Think of it like this: What was one-piece has now become two. 3 with the handlebars. Or you can ditch the 31.8" handlebars and go back to a 25.4" bar. I think the 31.8's are better.

I'd give a link to one, but I'm not sure about linking to a bike store on the internet in these forums. But all in all, this will cost you around $40 or more in parts + shipping. The bike store you went to should have explained this to you. I'd find a better shop to patronize.

thats what im saying. my LBS sucks lol. thanks everyone. looks like its back to ebay to get another handlebar. im gonna take this as an expensive learning experience.

heres the adapter. although seems like a lot of trouble to go through just to use a 31.8 bar. if i was going to change that much, i would just convert all the way to threadless (ie. fork and headset), which would only cost a little more...

I just did a conversion using the Profile Design converter with a Ritchey adjustable stem and 31.8mm bars. It was on my 1981 Reynolds 531 A-D Puch Steyer. I wasn't about to toss that fork and join the Carbon-People. It's beautiful and worth the extra $$$. But on a Moto...Hmmm...tough call. I'd say love is involved.

solbrothers

so, all id need is that profile design converter and a stem? doesnt seem that bad

Panthers007

If you like the Profile one. The Profile is considered the best in terms of strength. The Dimension one is black in color. Make a decision. LOL. Now price stems and see where you land. And remember: You want a 1" to 1 x 1/8th" converter. They also come in 1" to 1" I think. Or 1 x 1/8th to 1 x 1/8...so forth.

Get a good stem - not a cheapie from Uncle Woo Factory #31. They break. It's your neck.

fatigoworld

you wont be able to get much rise out of that converter, so he is right to go with an adjustable stem (not the prettiest of stems, no offense) . it just seems to me like it defeats the purpose of going threadless though. which is ease of use. you will have a threaded fork and headset, quill clamp, threadless clamps, and no rise. just not very functional. id still reccomend either sticking with what you have (plus new bars) or going all the way threadless.

Panthers007

The Ritchey adjustable is actually very, very nice. It looks good, too. It's really fine-toothed so there is no play at all. AT ALL. Good piece - but pricey. And easily convertable to another bike. Or resold.

fatigoworld

just looked it up. definitely one of the better looking adjustable stems. still think its a rather makeshift set up though. basically just seems like an overcomplicated way of getting around parts that dont fit instead of just getting parts that DO fit. the whole point of having a threadless set up is so you can just loosen a couple allen bolts to remove your fork, stem, bars, etc. i would prefer an all quill set up or all threadless set up, for sure....

if you do end up getting that adapter, grease it before you put it in so it doesnt get frozen...

Panthers007

Believe me - I did my homework and what I wanted just plain don't exist. I thought the adjustable would be a short-term fix. But I've changed my mind. It's as tight as the quill was with 1" bars. And feels more solid. It's a keeper on my vintage road-machine. And this from an utter perfectionist (admitted). I also collect stamps!
