BikeYoke Announces New Barkeeper Stem

Mar 15, 2022
by BikeYoke  


Barkeeper Stem

We would have loved to describe it as "sustainable“ or "e-bike ready“ or whatever is currently trending in marketing speech. So, no, it’s not particularly sustainable - as is nothing in our oh so glamorous world of high-end mountain biking. We’re talking about luxury goods here. Not a single person on this planet needs a mountain bike (not even a cheap one) in the first place. At BikeYoke we find it strange that companies feel the need to market paper packaging instead of plastic as sustainable. It should be natural for any company to design proper, enduring products, using as little packaging and waste as possible. That’s nothing that should be worth advertising and nothing, that we should have just discovered recently.

So, our Barkeeper is a stem – well, okay, it‘s a very nice looking stem, we think. It’s a stem for 35mm handlebars.It’s a stem that comes in 3 lengths: 35, 45, 55mm. It’s a stem that’s very light: 80g @ 35mm length with Ti-Bolts.

It’s a fairly strong stem. In cooperation with industry leading German test laboratory EFBE, using their EFBE Gravity/DH Bike-standard (GR TRI-TEST) as benchmark, the stems were tested and approved. Each TRI-TEST test program is based on three modules: Fatigue tests, maximum load tests and overload test in various load cases. All stem lengths were successfully tested to exceed the requirements of the strongest possible category for mountain bike components (category 5) of DIN EN17406:2021 and ASTM F2043-13.


Tested with an 800mm width handlebar, the 45mm version was even tested for 500,000 cycles,before machines were stopped. In this test-setup, only 250,000 cycles were required to qualify for category 5. It is a stem with an almost ridiculous attention to manufacturing quality and detail. For strength reasons, the stem body is firstly forged in a highly complex 3D-forging process.The critical surfaces are then precisely CNC-machined, then shot peened for additional surface strengthening. The logos and markings are then laser engraved into the raw aluminum and last but not least, the stem is anodized, giving its black-in-black exquisite looks. The attention to detail in manufacturing– even on the inside – is marvelous.

Nevertheless – it remains a simple stem, it‘s main purpose being holding a handlebar in place, and BikeYoke knows that the benefits of a one piece design (strength/weight ratio, unique looks) does come with a limitation in handlebar choice. Some handlebars may not fit but it is expected that most handlebars up to 30mm rise should work. Race Face SixC in 35mm rise is an easy fit. OneUp’s popular Riser bar (20mm rise) was a rather easy fit as well.

On the other hand,there may be handlebar, also with lower rise, which do not fit.It greatly depends on the shape of the bend, not mainly on the rise. That’s also why the stem comes with a simple but effective installation aid, a wedge, which allows to widen the clamp opening to 9mm, for even more installation clearance.

Oh, did we mention it comes in a really simple cardboard/paper packaging? How green of us.

Prices: $89 / 89€ / Ti-bolts kit (additional to the included steel bolts): +$25/25€



Not much to say about a simple top cap, I guess. Even with it is one-piece aluminum design (no steel bolt) and super-light weight (maybe a tad over 5g), it’s mainly there to help adjust your headset play and then just look really good. It’s finely machined all the way from top to bottom, then laser engraved and then black anodized for a very nice touch. It will fit any standard (M6-threaded) star nut in your fork steerer. Price: $14/14€.



Aimy is a small but neat little gadget, that is particularly interesting for everyone who likes to wrench on his bike. Taking off the stem and handlebar unit usually makes you wish you had more than just two hands to do whatever you need to do and at the same time keep the fork from slipping down, all the way through your headtube. Rather than just slide onto the steerer tube, like an ordinary headset spacer, Aimy is clamped onto the steerer tube, not allowing the steerer tube to fall through your headset, once you take off your stem.

Handy, right? Other than that, Aimy serves as a regular headset spacer, measuring 8mm tall and weighing in at 8g. Additionally, you can use Aimy as a reference to easily re-adjust your handlebar for perfectly straight alignment in case your twisted your stem for whatever unfortunate reason. Aimy is clamped, and won’t budge, even if your stem does and as long as you had previously aligned Aimy’s clamping slot with the one of your stem, you have a simple but effective indicator for the straight handlebar position. Aimy is machined from aluminum, featuring a stainless steel clamping bolt and will fit any standard 1 1/8“ standard steerer tube. Price: $16/16€.

 Call me crazy, but a stem is a component where I don't mind a few extra grams, just for peace of mind.
  • 78 9
 Extra grams won't help if the stem isn't properly engineered and manufactured. Within certain reasonable limits, there is hardly any correlation between part weight and strength.
  • 48 1
 Near net forging like used in this stem is miles better than all the expensive cnc stuff, stronger, lighter and generally cheaper but people just have to have pretty colors so nobody buys these.

Yup. I’m a big fan of Syntace stems for this reason. I think Ritchey goes this way too
  • 20 2
 I’m not too worried about lightweight stems, but I’m not saving 20 g to get a stem where you have to thread the handlebar through the stem. Such a unnecessary feature. Syntace stems FTW.

 @Sshredder: So no data will ever sway or change your opinion? No expert who has trained their entire life to create durable stems can be trusted? You're going to rely on your relatively small sample size of anecdotal information to drive your opinion? That's a pretty small bubble to live in. I'm not saying Bike Yoke has done all their due diligence and Design Validation (field/beta) testing, but to say that it's light, it'll break"... is just...uniformed. I'm not saying that your experience is invalid, but it's a very, very small data set, and you may not be aware of the design and manufacturing decisions that impact strength.

You have to realize here that there are conflicting requirements. Removable faceplate, strength, & weight. They chose to compromise the removable faceplate requirement (for simple bar replacement), and prioritized weight above that.

 @UtahBrent: I agree with Sshredder, I always amazed how many consumer products make it to market and still fail or have a recall. In other words, the engineering is only as good as it is applied.

Not to mention, when validating or verifying a design using ASTM standard (in any industry) you would be shocked to see how many perfect on paper designs fail.

The following saying will always hold "well it looked good on paper".

The manufacturers who do things right are those who not only have design expertise, but test the absolute shit out of their products, and go above and beyond ASTM standards. There is no proof like a field testing.

what I've noticed over the years is many pop up bike companies, specially catalogue frame manufacturers, have a tendency to rely on their customers as field test dummies!
  • 6 0
 @BoneDog: I don't think Bike Yoke has given any indication in their past product releases that they suffer from a lack of Design Validation testing (field/beta) where issues would be detected. I might be wrong, but my experience with their seat posts has been excellent.

I'm also not advocating that testing should be driven only by industry standard tests, or that field testing does not hold critical value.

 @Sshredder: i rode a 17lb rigid carbon SS at 200lb rider right. Had a 100mm Easton EC90 XC stem and EC90 bars. I hit 3’ drops to flat, nasty rock gardens, rough rutted trails and had all sorts of crashes on that over the many years (and thousands of miles) I owned it. Took me a while to trust the stem, but never an issue with a single crazy light part failing in spite of tons of abuse.

 As far as adjusting your handlebar for perfectly straight alignment, just throw a straight piece of scrap wood across the fork stations and line it up with your bar.
  • 10 10
 This thing primarily handy when traveling with the bike in a bag or case. Not a situation where straight pieces of scrap wood are readily available.
  • 18 1
 OOh, nice idea!! I've been wishing they'd just laser etch the back of the steer tube with an alignment line.. Line it up to the slot in the stem and you're good to go.

Tho I bet it’d be a hassle for the fork manufacturers, as there’d defiantly be more tooling involved, since the line would be etched before the steerer was pressed in.

 @hllclmbr: Yep. This has been gone over a thousand times in the comments and forums. Not going to happen. Rockshox patented those annoying sag markings on the stanchions. Pretty sure they've considered this.

 good idea when you have scrap wood around to do that... I think it's hilarious where I close one eye and it looks off so I bump it, I close the other eye and it looks off the other way... Smile

I use a problem solvers headset spacer so that I can keep the steerer tube in place when I change spacers around with my one up EDC threadless carrier that doesn't have the star nut. Never occurred to me to just make sure the PS spacer is 100% straight and then the rest of the time I mess with my bars/stems/spacers I can use the problem solver to align with.

Good idea!!

 @dancingwithmyself: The only thing annoying is you dancingwithyourself and the comment. As for those Sag% markings are concerned, they are a wonderful and simple way to get your shit dialed. No need for a calculator and measuring tape just to set sag!

 @Ttimer: Could use anything with a straight edge. A PVC pipe, a dowel, a yard stick, a broom handle, a cutting board, a golf club, a toilet plunger handle lol
  • 2 5
 @50percentsure: Important is that is straight indeed. Most of what you mention is more straight than the pieces of scrap wood I've come across. If it is sufficiently straight and long, it is no longer scrap wood.

Obviously this only works if your stanchions are straight and that your bike has two upwards facing and uncovered (so no fork boots) stanchions. So no Trust, no Lefty or Headshok, no USE SUB, no USD fork, no Structure bike, no German A Kilo, no rigid fork. Look I'm sure it sounded like a great idea but if I put it like this I'm sure everyone thinks that you'd be lucky to find a fork where this trick would actually work.

 @likeittacky: not if you play around with different air shaft lengths. Or say you buy a complete bike and bump the fork travel up 20%. Or say with the supply crunch the only way you can get a fork is buy the wrong travel and replace the air shaft.

And that's not even getting into the fact that with modern HTA, sag is even less of a valid way to settle on a final spring rate.

And do you really need a calculator to multiply by 15 or 20%?
  • 1 0
 @likeittacky: Meant bump travel up 10mm
  • 4 1
 @dancingwithmyself: There you go playing with your shaft again HAHAHA.... and creating too many scenario's.

BTW Its referred to as an air spring, not shaft, which is the stanchion tube it rides inside.
Albeit you are correct about how to settle on the proper rate for a given rider, style and terrain. Hence, once the sag is set to the individual preference, the markings make quick and easy work whenever a pump is attached to increase or decrease air spring rate.

Some people are not good with math when they are at the trail head with a group of buddies waiting for you to re-calibrate your suspension for whatever the reason.

As for increasing travel by changing the air spring, there are markings to indicate +- % of travel to.

 @vinay: True, a piece of wood that is not scrap would also work! I do a lot of carpentry and the number of pieces of short scrap wood I have that don't have at least one straight edge is pretty rare actually.

Honestly though, without exaggeration I bet there's a hundred other items in everyone's home that could work for this purpose. It's a tough trick to have fail.

As far as saying forks with 2 exposed stanchions to line something up are so rare you'd be lucky to find some...Not sure what you're riding? I was thinking of forks with 2 exposed stanchions like you'd see on any Fox, Rock Shock, Marzocchi, DVO, Manitou, MRP, Öhlins, EXT, etc.

Try it, it works a treat. Surprisingly accurate and easy when you hover above the bars and eyeball the straight edge below in proper lighting.
  • 2 1
 Just put your face above your handlebar and look down at your fork lowers/axle/stanchions/etc. Line your bar up, on both sides of the bar, with the same exact spot on your fork, on both sides of the fork. Straight bar in seconds, nothing else needed, no wheel removal needed.

 @rickybobby18: True true, but it is easier lining up correctly against something 80cm long like a wood scrap vs something short like a fork arch etc.

I was unable to fit a 40mm rise bar in that stem (U.S.E. Ultimate FLOW). I was barely able to fit a WHISKY No.9 25mm rise bar because of the hard bend in it; scratched it a little.

 If there is one thing (okay, one of many things) from the 90’s working in shops I’d never want to experience again it’s putting riser bars through 2 bolt stems. 35mm may make the process easier, but this is never something I thought we’d go back to.

 I like how the writer of this article prepared his/her words as if he/she anticipated the pinkbike comments/remarks to be had on another stem.

If you change a stem, they are usually all different heights which means you usually need to adjust stem spacers. So you would probably need to be taking that Aimy thing off anyway.

Using it for an alignment gauge... I guess so....

Maybe I was dreaming but wasn't there an article at some point about fork steerer tubes with centered notches that could be aligned with special notches on spacers and stems if they were all developed to the same standard? Essentially making it impossible to set up your handlebars crooked. That would be an idea worth pursuing if all manufacturers adopted a standard.... Or maybe that's not a good idea because knowing the bike industry, the notch size would change every two years and you'd be forced to buy new everything to make a build work.

 @Ttimer: put the Aimy at the bottom, against the headset and now you can play spacers and stem height. Just factor in that it's an 8mm spacer.

 Funny I was only thinking about that other stem article from a small manufacturer that used downplaying tactics to sell it... (it's just a stem...nothing special bla bla bla)...the irony of trying to downplay stuff to create empathy and come across as giving a shit about the customer...a bit of reverse psychology to try and get you to buy it. Yea it's just a stem we know...and no it doesn't look particularly attractive either...one of the few things that makes one stem stand out over another...and yea all stems pretty much are durable and non environmentally friendly. So actually ironically rather than listen to 2 paragraphs of humble spiel...I'd like to know why should I buy this stem? Remember marketers...sell me this pen!!!

 I had a 77 designz stem, that split. Then the replacement one snapped on one of the clamps. That was the scariest thing that's ever happened to me! Fortunately I was OK but my free replacement stem is still with 77 designz as they don't offer your money back and there's no way on earth I will take that risk again. I now run a burgtec that is double the weight of the 77 stem and did I notice any difference? No!

 I remember a time when the lightest stem for aggressive riding was 250g. Raceface will tell you that a CNC machined stem is better. Its isn't. Forging aligns grains and makes a stronger stem. Same reason forged shimano crankarms are better than CNC cranks from billet like hope or raceface does.

 The stem and cap is pretty nice, I like their approach. Non condescending. That being said,
Here’s a solution I discovered from thinking outside the box (not having enough spacers) I ended up using one of the “backup rings” that you use when installing a quad seal from a rockshox air can, it fits snug and flat when compressed with all other spacers, you take off the stem along with all other spacers and you’ll see that ring holds the fork in place without sliding.

 @Keegansamonster: Overkill is underrated! My team usually requests testing-to-failure rather than just testing-to-compliance when we order a lab fatigue test. It's great to be able to correlate the virtual analysis model you've made and to understand how much margin is left in the design for the inevitable future occasion when sales/marketings comes and says, "we know the product is rated for [original spec X] but a customer wants to do [abusive loading Y], is that ok?"

 @wyorider: That doesn’t sound like an issue related to the weight of the stem… At a certain level, every change has a risk of something going wrong at the wrong moment. You can’t just pick a random variable and act like that’s the thing that makes change risky.
  • 1 1
 @Blackhat: I've never before or since had a stem twist on my steerer like that. As an isolated variable, the stem was dangerous. I suspect it was a combination of low stack (less clamping surface on the steerer) and flexy titanium bolts. But-it was unacceptable for a bike being ridding hard on consequential lines. And Syntace marketed it as appropriate for that kind of use with a lot of "serious" testing.

So once again I'll say-I'd like some real world validation of the stem in this article. I'm sure in the specific tests applied it's done great. It is probably plenty strong. But there is no substitute for actual outdoor beta testing.

 @Sacki: i might have mistaken m4s for m5s but im pretty sure most of my stems are m4s. I had a old azonic with m6s and it was heavy but they would NEVER twist lol

 Dang, looks good but 40mm stack

 Really depends on the bike's stack. Some manufacturers have realized that if you make a frame with a short heat tube and long reach, you can adjust to your perfect preference with spacers (that also shorten reach), handlebar rise (if you want to keep the long reach) and stem length (for fine tuning weight balance).

Knolly is a good example. Large sized frames have 491/492 reach but just a 103/106 head tube length.

 Aren't most stems 40mm in stack? I know Syntace and Spank have sub 40mm stacks...but the vast majority seem to be 40mm.

 has anyone ever actually broken a 35-50mm alloy stem before?

 The stem itself no, but I've seen broken stem faceplates. They may have been the result of ham-fisted home mechanics though.

 Watched a guy behind me break his stem clean in half off a drop in Whistler. Scary crash. Give me the extra 20 grams of material and let me keep all my teeth please.

 Never broke one, but had a Syntace that would twist on the steerer under load. So it was only unreliable in clutch moments when I had to muscle the front end.

Needless to say it didn’t stay on the bike long, and the Spank stem I replaced it with was utterly trouble free.

Syntace makes good aero bars-and that’s about it.

 Aimy is a great idea, and decent price for a stem that light.

 I think BikeYoke is doing a fantastic job with their droppers and most other products, but that top cap has been available from AbsoluteBlack for years ...

 @FR33DOMdotCOM: stems have been around for years too.

 @FR33DOMdotCOM: I have to disagree. Ours is not "premium" as opposed to Absolute Black's.

 @Sacki: That´s ok. Yours is not innovative, but at least it´s not cheap ...

 Aimy thing can f*ck right off. What a load of bollocks. A solution looking for a problem to solve.
