    Threaded to threadless adaptor Qs

    This will be on an SS bike, if it happens...
    I have a nice frame/fork with a 1" threaded setup.
    I was looking at those threaded to threadless adaptor things. A few questions:

    Do these hold up as well as a regular 1" threaded set would?
    Can you still adjust up and down like with a regular quill stem by moving the adaptor up and down?

    I see this as a nice option because I have a bunch of threadless stems lying around, and I am finding a relatively limited selection of decent quality affordable threaded stems with a removable faceplate.

    If you have one of these lying around unused, PM me.

    in this pic, it's the chromey thing that the stem clamps to. they go for $20 new.

    I used one on a fixie commuter for a while. It's easy to adjust up/down just like a quill. I think I sold it with the bike...but I'll double check. I wouldn't hesitate to use it...like you said, it gives you better stem options in my opinion.

    The Profile converter is smooth unlike the Nitto which is knurled. You may want to go with the Nitto and perhaps a more robust stem.
    did the adaptor slip inside the steertube, or did the stem slip on the adaptor?

    That's a stem adapter quill on this bike. Got it from Nashbar for something like $11 or something. I raised it from its 'sit-in' position, dropped some spacers around it, then clamped on the stem and tightened the whole thing down. Rock solid. I know this because I crashed on this bike on Monday and the stem adapter stayed put.

    Good job!

    I've used a coupla 'el cheapo ones for years now, with no problems slipping, etc.

    You clamp your stem to a smooth steerer tube, or to one of these jobbies....really no difference! (other than lack of star nut...)

    That looks like a sweet ride. I love the color and the very smooth welds. What is it?

    nashbar

    I have the nashbar 1 1/8. No problems. No movement. And you better believe I've crashed. Not too flexy. And you have a little bit of height adjustment. There is a min insertion line. mmmm minimum insertion...

    I tried one of them chromey things

    Adapted a 1-1/8 threadless softride stem to a 1" threaded fork using the stem adapter and it worked fine. There was vertical adjustment though not as much as a normal threaded stem. I had no problems with twisting (and don't say anything about twister)

    I don't have the bike, stem or adapter anymore but I would go that route again if the situation came up.

    been using one of these on my commuter for 2 years. no problems other than being a bit heavier than either pure threaded or threadless setups.

    Got it on my older Giant TCR, with an ahead Salsa stem. Never a single problem. Compared to a heavy quills tem, it's not even that heavy. The spacerless height adjustment is a big plus, but I never did use it. Gotta remember it though, a buddy will borrow my years-of-dust Giant soon, for cardio road training. He'll like the feature for the last hour of a longer ride, I know how I long for such a thing on my longer rides.
