Have you ever been on a ride and thought, "I wish I could shorten or lengthen my stem on-the-fly?" We haven't either, but the 3fstech AIM stem is designed to do just that. A handlebar mounted remote releases the stem, allowing it to be set at either 55mm, 95mm, or 120mm in length. Total weight is claimed to be 400 grams, including the remote. For reference, "regular" stems usually come in somewhere between 100 and 150 grams depending on their length.
How much will it cost? Well, it certainly won't be cheap, with final pricing expected to be in the neighborhood of €275.

How bout it?

If you do...I got a bridge to sell yeas....
Real Cheap.
That was just classic...Bravo!
15 shifters on the bars, need a pilot's license to ride that piece of alu/carbon. But You can set everything without going off of the bike. Just like a smartphone market. Control everything, unless you you're out of battery.
But it only has few (3-4 or maybe 5) locking positions. Looks like they're spread to about +-1 inch (I mean locking positions). Do you think it would be good to determine the best riding position with such a wide spread?

On a positive note, I love the little superimposed air-gun sound when they move it. Quality edit.
dropper-seatposts make perfect sense.... this one? in theory yes, but on my bike? NEVER EVER!
Not even the Great WakiOZ hath forseen this in his prophetic WakiLeaks. Is his vision of the future fading? Or does the future hold no more than the foretold E-pocolypse of which this is surely a sign of, and he is simply trying to steer the future away from death, destruction, and what can only be certain steerer tube impalement? Oh WakiOZ, please tell us. Is this our destiny!?!
OK, less necessary than a dropper post, but when bikes will have adjustable geo (strive style), dropper post + adjustable seat angle, stem and handle bar too, and why not tire pressure etc...
30 years ago who would have welcomed droppers and E.I. shocks?
1) Suspension Fork, why do we need this when we are doing just fine without the extra weight, wait my filings in my teeth do not fall out anymore
2) Rear Suspension, why do we need this when our suspension fork does the job already, wait my ass and back don't hurt as much now
3) Disc brakes, my V-brakes work just fine EXCEPT in the rain and mud, oh wait even when needing to stop
4) Adjustable seat-post, nah way to heavy and cumbersome, wait how did we every get along without this
5) Adjustable geometry, why do we need that? Wow, 1 bike that can do almost all types of riding, crazy
This could go on and on but at the end of the day human nature since the beginning of time is to always resist, deny, accept, then adapt. Ride on friends, Ride on....
I think the idea is fun to play with and there are maybe sometimes for some riders where this makes sense.
But, my biggest worry is if the stem actually moved on a jump or landing a jump. That would be scary.
Then, like most dropper post, they have a slight wobble in them, I wonder how this relates to the hands.
If there was any noticeable wobble, that would kind of suck.
Concept wise, its a good idea in a way.
Think about, having your AM bike set up for XC while climbing then move it to a more DH position on the way down.
That actually makes sense for an Enduro or XC race just as a dropper post would!
Ummmmmm!
Have you been on this stem?
How does it feel?
I like the idea but have some concerns.
I usually ride DH and FR so my bikes have never been XC specific!
I also noticed a huge loss of climability when I went from a 70mm stem, to a 50mm. But the 50mm allowed me to get really stuck into the steeper, more technical tracks when descending.
So a 120mm on that negative angle would make a huge difference, all while keeping the descending where you want it (the stem will also me strongest in the descending position)
Not that I'm wanting one but, like all new technology, I'll wait a few years after it hits the market to let them work out all the kinks...if it's still a thing by then. (See: Hammerschmidt cranks)
But you must be right handed @villager, so I will not go into details as to why that is important, rather than "retarded"
The modern world of MTB is about customization.
No left sided rear gear select, makes almost as much money as no bead lockers, for those who ride tubeless. If you are going to re-leave people of their money. Do smart, rather than smrt.
The best part of ideas like this is the ideas that they help get kick started. Maybe something else will come from this that's more useful and not so heavy. That's a lot of weight to have hanging on the front of your bike.
but it would be interesting and more subtle
It would be a far better product with side rails (so it can be shorter) and 35-80 extension for the long tt trend.
For me; at 53; Im done breaking arms going of ledges! its more trail riding! I love the idea! I takes my reign sx and with an adjustable seat post and turns it into an xc bike! Then, drop the seat, bring up bars closer; back to free ride again! nice!
What does it cost? How much! I can buy a good junk of a single speed 27+ for that!
I like that in our current season of ever changing standards for the sake of refinement and marginal gains, someone is thinking outside the box. Better yet, it's widely compatible with people's existing rides.
What I don't like is that I don't think it solves a problem... At least not for me. My high stack height combined with a short stem is awesome going downhill, but it's also great going uphill. With the recent trend of long reach and steep seat angles, my experience is becoming more and more common, and there is simply not enough advantage to gain from a dropper stem.
Or... Maybe I'm wrong. Maybe there would be a significant advantage. In the past, I've never had the urge to play around with stem length because I prioritize downhill and always bikes that fit. However, now that the door has been opened, maybe I'll do some back to back testing with a long negative angle stem and see what happens.
Regardless, I'm not interested in the product at this point in time. My handle bars are too cluttered. I have 2 brakes, rear shifter, dropper post, and remote lockout. There's simply no available space. The ergonomics are already a little difficult. I think that the industry would have to make some giant leaps in product integration before I'd consider adding more controls.
Ideally, I'd like Shimano and SRAM to make their electronic drivetrain systems open source so that other manufacturers can tie their systems into shifter controls. Not only that,but the systems could (in addition to independent control) be then set up to run through customizable modes where perhaps a single button would lower the seat, lock out the fork and shock, and move the handle bars forward. Pressing that same button again could cycle the bike back to descend mode.
The technology already exists to do all this,but it will take some time for the manufacturers to break down the walls that they've built around themselves. I foresee SRAM as being the first company to produce a fully integrated product line since, at this time, they are the only manufacturer capable of providing a complete set of components for a bicycle. If SRAM is successful in this arena, and if they do it soon enough, it could spell the end for their biggest competitors Shimano and Fox,at least in the high performance market.
Bye bye top tube!
Should put an advisory on there "only guaranteed safety with triple clamp forks".
But yes its still ugly and overpriced. Sram its your turn.
This is either the worst business idea ever or a cunning plan to extract cash from morons who want on the fly stem adjustment.
Bahahahahahahahahahahkjwbfcsldkbfnal\w
How much will it cost? Well, it certainly won't be cheap......well it bloody should be cheap cause it's the most retarded thing I've ever seen!
and 26"+ is next not 31", because it has all the advantages if 27.5"+ while weighing less and being more nimble ...
Also, what the hell is a "rally mountain bike"?
I had few adjustable stems... They may sound like a good idea, but they are just a pain. And dont work well.. Creak and flex...
Nuff said
I could use a road bike to ride to mountain than frame grows shocks and tires and turns into 160mm travel bike...
it doesn't matter for the other positions since you'll be standing on the pedals
and btw what about adjustable bottombrackets?
Can't wait to have that on my bars too !!!
