    Quill stem adaptor a good option?

    I have a 1990 Trek I'd like to get a shorter stem length on. It's expensive to find quill stems anymore and I saw the quill adaptor posts that you tighten in and then bolt the modern neck onto. Anyone use these? Is this a decent option in order to fine tune my older bike? Will it end up heavier or more expensive than quill?

    I don't have hundreds of dollars to convert my bike to threadless with new forks, although it would be sweet.

    I have one. It works real good. Actualy it better because it allows for easier bar/stem changes

    If you posted the desired length of quill stem you need, people here might help you find a deal.
    The addition of a stem adaptor may be more convenient, but is the inferior option.

    How short is short? An adapter is like what - $20? A cheap stem say another $20?

    Food for thought: if you aren't dead by 2050, you and your entire family will be within a few years from starvation. Now that is a cruel gift to leave for your offspring. ;)

    I have a Profile Design stem-adapter on my Puch - changing it from a 1" to 1 1/8" to accept modern stems. Works like a charm. Allowing me to use 31.8mm handlebars that I like.

    No way....they work extremely well and to be honest I think they stiffen up the front end.

    ^only if the quill stem being compared to is wimpy in the forward extension.

    The OP can probably find, from the myriad of stems out there, a quill stem which will beat any adapter/threadless system in looks, stiffness, safety, weight and price.

    the good looking, safe, light weight quill stems are quite pricey, even used ones.

    the really ugly quill stems which are somewhat heavy can be had for cheaper than $35, sure.

    the adaptors aren't any less safe than quills. In fact the threadless stems clamp down on the bar with much more surface area than quills will and with open faces it's safer too.

    Mine made my front-end rock-solid, compared to the old skinny alloy quill-stem. One can say how they are bad because blahblahblah. But I have practical, hand's on experience that says: They work great!

    Great info everyone, didn't know it would get heated in here.
    I'll look into it as an option. I'm hoping to pick up a smaller bike for my wife today and I'll probably be doing some custom fitting for her.
    Thanks

    There is no way this is true. It uses the exact same interface as a regular quill stem. You are just imagining things.

    The interface may be the same but the extension part of the stem is quite different. A threadless stem uses a large diameter tube while the quill stem uses a smallish, solid shank. On a long reach stem, the difference in stiffness could be quite noticeable.

    I switched from a Nitto Technomic quill stem to a Velo-Orange quilled threadless adapter and threadless stem, and IMHO it's a significant improvement. The adapter and stem are a little heavier, though (V-O adapter is 272g, 110mm stem is 140g for a total of 412g; the Technomic quill stem with 110mm extension is 390g).

    Good point. I've had quill stems on old road bikes where the flex was quite visible. It was obviously twisting on the horizontal plane rather than bending vertically. Never seen (or felt) anything like that, even with really cheap threadless stems.

    Here's one application of the threadless converter. I like it, actually prefer them to the Technomic quill to increase height.

    Ditto.

    I seriously doubt the increased stiffness (or, maybe "lack of flexiness") and stability over my old Technomic are my imagination.

    I should look into this for my 2nd bike. I've noticed I ride on the bars behind the brakes rather than on the hoods. I had both bikes out with a friend on one and then we swapped. It was very noticeable then. But then I'd have to change bars too, and tape, and ...and... where does it end?

    Ha ha, yeah, gotta love the passion.
    Odly enough, I just picked up a 1989 Centurion Dave Scott Ironman bike for my wife for $50. It has a Nitto quill stem about 1" shorter than mine... So I bought a stem for $50 and got a bike with it for free!

    Sounds like you just need a shorter stem and/or shorter reach bars. You don't need to go with a quill stem adapter for that purpose though I just did all of the above on my wife's bike. It's a men's frame so to compensate for the reach I went Bontrager short reach bars, a 60mm stem, and a non-setback seatpost. Fits great now.

    I have a Ritchey adjustable-stem mounted to my stem-converter. Those Ritchey adjustable-stems are rock-solid (here it comes again!) and the ability to alter height/reach is most welcome.
