Singlespeed & Fixed Gear - 26.0 bars in a 25.4 clamp???

anyone done it? or anyone have opinions? i feel like it wouldnt be that of a deal but was curious if people have done it or are running it. any input is nice. even negative...i like to laugh.

thanks for the help amigos

Friend of mine has done it with his 25.4 Thomson, according to him he's never had a problem.

thanks for the quick reply. thats what i was thinking. since it keeps becoming harder to finD 26.0 thomson stems since they are out of production i wanted to be able to run pursuits and flats and they have different clamp diameters

I bought 26.4 Cinelli giro bars to go with a Colnago(ITM) 26.0 stem. The bar doesn't sit flush in the bars. It may work for you but it didn't in this situation for me.

So are the thomson stems on www.bikeparts.com all 25.4 even though they say 26?

I ran this set up for a little while. My bars now have dents in them from the stem and I am a little frightened to use them now. they are probably fine to be honest

Stretching 26.0 to 26.4 used to be fairly common, and frowned upon, when Cinelli was still rolling 26.4, but that was on single bolt stems so it may be more palatable on a 4 bolt stem, but you might not get as good of contact between the bar stem. If you ride really aggressively or put in lots of miles you might want to hold out for the right fit.

You over tightened them.

Old style quill stem - Bad
Two bolt pop top - You probably won't die, but make sure you've got good dental none the less
Four bolts - Either way works just fine. Just don't go gorilla on tightening this down

I like how 7 posts detail saying it's ok without even asking the OP if it's a quill or threadless stem. Please everyone, just stop posting incorrect nonsense before you get someone killed or seriously injured.

it would be a 4 bolt threadless stem just to let you know..either a thomson elit or nitto

I was also wondering if this was for a quilled stem. No sweat doing this with a removable face plate but can be very difficult on a standard quill stem. I've actually pryed the heck out of my Nitto track stem and inserted 26mm bullhorns. It's still holding strong after 4 years.

yea i figured it would be cool with a removable face plate. thanks for the help amigos

now Nitto UI-5GX Threadless Stem or thomson elite?
i would probly get the nitto in 90 and so far i havent gound the elite in a 90 but havent looked hard. so suggestions? preferences? opinions?

i got some Nitto 2500AA as a gift which are hte 25.4 and have some bullhorns but they are on my beater so i might get some pursuits. whats the difference in hte rb019 and rb021??

ui-5gx is a solid stem. that's what I run.

rb019 is flat. rb021 has a drop.

Please everyone, just stop posting incorrect nonsense before you get someone killed or seriously injured.Please explain how a quill or threadless stem would affect the stem/handlebar junction differently.

You should now what you're talking about before talking sh**.

threadless usually has a removable face plate, quill usually doesn't. OBVIOUSLY

Because you're bending a piece of aluminum. Generally considered a BAD idea.

i did it with a quill and just pried the clamp open w/ a crowbar... pretty ghetto/lazy/cheap of me but so far no issues

Oh for **** sake...

You know what, forget it. Just jam a set of these in there and forget I said anything:

thanks for the helpful posts amigos....i knew it was threadless. i have a stem on it currently. i figured after my second post where i talk about gettin a thomson stem everyone would assume it was threadless. i guess i was wrog

Because you're bending a piece of aluminum. Generally considered a BAD idea.my point is that the way the stem mounts to the fork, has nothing to do with the way it holds the handlebars. The photos should make that point obvious to anyone that isn't blind.

Don't pretend you didn't edit those pictures in there after I wrote that. You know as well as I do most quill stems don't have a removable faceplate.

before threadless stems became the norm, many quill stems had removable faceplates.

I stand by what I said in my first post to operator.

FWIW after the first reply, the OP stated he was planning on using a Thomson stem.

OP, there's some misinformation in here. there's no way in hell i could fit a 26 bar in the 25.4 clamp on my elite. maybe you're using a bulge formed bar that's not quite 26, but any of the sleeved bars i tried (mavic pursuit, nitto jitensha studio) would definitely not fit.

alright thanks chase. i have some nitto 2500aa i got as a gift from a friends and was hoping on being able to run one stem and switch those out with pursuits which are 26.0 but the straights are 25.4. i guess i'll just run straight bars for now.

any other opinions

my advice would be to acquire a 26.0 thomson through ebay or a bike shop that has some left in stock, and use a shim with the 25.4 bars.

yea i actually did soem lookign and found one. its 110mm and im not sure if that would be to long i need to measure my current one
