Bike Yoke is a small design company founded by Stefan Sack of Bionicon fame, who believes that there is a healthy niche market for technical upgrades designed to enhance the performance of popular mountain bike models. Bike Yoke’s first product is an alternative shock extension yoke that allows Specialized Enduro owners to swap out the proprietary damper with any suitable shock. The replacement yokes will ship in March ’16 with an MSRP of 88.99€ (USD TBD).
Bike YokeThe CNC-machined aluminum replacement fits standard, ½-inch shock eyelets and is similar to yokes used by the likes of Pivot Cycles and Lapierre. The new yoke duplicates the stock geometry, uses the existing Specialized bearing hardware, and arrives with all the necessary bushings and bolts to interface with your chosen brand of shock. Yokes are available for 26, 27.5, and 29-inch-wheel Enduro models from 2010 to present. PB will be reviewing Bike Yoke's new link soon.
Stefan is working on additional aftermarket yokes, as well as alternative linkage offerings intended to enhance suspension kinematics and geometry. All products are designed and tested in Germany and produced in Taiwan. At the moment, Bike Yoke’s products are available directly from its
on-line store.
Hmm...think SpecialEd has a bit of an image issue?
Good on Bike Yoke for doing what they're doing.
I CNCd the RP2 lever for one of my shocks a couple of weeks back, works just as good and it has my initials.
The strokes and shock lengths are noted here and the differences between original and Specialized shock lengths are also described:
bikeyoke.mysimplestore.com/p/technical-information
Specialized uses standard strokes on their shocks, only the length is different. And using a BikeYoke with the recommended standard standard shock will get you the same overall length and and stroke as original. So it won´t change geometry or travel.
The old style yoke is super prone to creaking and it puts a lot of extra force on the shock. Back in like 2011 specialized used a yoke just like this and all their bikes creaked. The new design is a much stiffer interface.
I still think is good that small companies are doing aftermarket parts though.
The aftermarket one has a DU or igus bushing in between. As soon as that wears from being cycled in an unintended direction it's going to introduce a lot of bending to the system. (And be REALLY bad for the shock)
2) Spesh can't sue, but I'm certain they wouldn't honor a warranty on a frame running one of these....
that's why I will not buy a Spesh in the future (although I love to ride their bikes)
but it's a shame, that for some parts, we NEED an aftermarket.
and it would be soooo easy to avoid it - linke in this case (Spec. Enduro)
I've had one and swapped the CCinline because it unfortunately didn't work properly. I had to wait for the replacement (Rock shox). When that shock needed to be repaired, I couldn't ride my bike, because there was no replacement shock available (due to the proprietairy shock mount)
For example many Enduro 29 owners use the 27.5 yoke to slacken the head angle and despite the fact that it is made by Specialized it still voids the warranty.
Personally I knew the Enduro restrictions before I bought it so I won't bitch about it.
Personally I think that these are good news also for Specialized since there will be people who will reconsider buying a Specialized bike now that they can put a standard shock.
As far as I am concerned I have already put a proprietary Monarch Plus Debonair in my E29 but I will order the yoke anyway when in stock because it is good to have.
You are correct sir.
This design will correct the issue.
I'm not sure what "side flex" you guys are talking about in a good way or what side loading issues the current design has. Mine has zero issues even with bike park use.
1. The fact that it had a yoke on it to begin with, creating a far longer shock/strut unit that has a huge buckling tendency because the load is now going through the pivot instead of the DU, which is now 120mm or so from the shaft bushing at bottom out instead of 20mm. Only five or six times worse...
2. The shocks that were breaking were CCDB coils, which had an 8mm shaft (low 2nd moment of area compared to a half inch alloy shaft)
3. The CCDB coils also have very low buckling rigidity to begin with - they all have noticeable play in the shaft bushings and piston that most shocks don't. This makes buckling even easier.
Long story short - yokes suck. But if you're going to have a yoke in the first place you might as well be able to swap out a shock when you break it.
The specialized yoke is stiffer than the bikeyoke one or the ibis/kona designs. Meaning it's much less susceptible to buckling than the other designs.
I was talking about new shocks. It's economy of scale. Higher production volumes and wider availability of normal shocks results in a lower price.
Hi Jeremiah,
We are getting really a lot of inquiries about Stumpjumpers.
May I redirect you to here:
bikeyoke.mysimplestore.com/products/bikeyoke-for-stumpjumper
You can find all the information about our plans regarding Stumpjumper in the red link in the article description
However, here is the direct link:
www.dropbox.com/s/blhqm18sp2ku1sa/Stumpjumper%20BikeYokes.pdf?dl=0
It seems like you are one of the lucky ones, since your shock has a stroke of 51mm... ;-)
It would be nice, if you could follow us on facebook or give us some likes and share our news. We will always keep our fans updated on new projects.

All in all, a great product I think but really late to market as there are now major player options for aftermarket shocks anyway.
The SX 4x frame shock mount will work on the Trail models with the 7 and 7/8 by 2" stroke shocks.
Travel will be around 155mm.
If you want to run the 170mm trave,l you
Will need to cut about an inch from the mount and run a 2.25" stroke shock
What I and I think others are looking for is a universal shock mount to give the freedom to mount different and better shocks. Vivids, CCDBs, BOS etc.
I'm not sure Specialized can stop them from making this part, if they can and do then I will have to boycott Specialized for life. I already bought an Ibis because of Specialized proprietary shocks and mounting. The Stumjumper evo I test rode had a broken shock twice. After the first time I had to wait over a month for the shop to be able to fix the shock (it had CTD and auto sag-what a joke that feature is) I flipped the blue switch to start a long fire road climb and the shock lost ALL damping. both compression and rebound. riding the downhill portion of the trail was like riding a pogo stick. the poor quality of that shock combined with the difficulty I would've had getting a replacement was the main factor I didn't get a Stumpjumper evo or an Enduro 29.
This product is needed and fills a niche that no one else has filled yet. And if Specialized is smart they will begin making their own version of these yokes instead of suing all the small guys.
There was when I got my first mountain bike in '89. There hopefully be someone that makes more improvements to make awesome things even more awesome!
He saw a need for something, then had the balls to fill it-on his own dime.
This is not unlike the 42t cogs companies like Wolf came out with(I can't remember who the first one was) so you didn't have to spend through the wazoo for an 11-spd to get a shorter climbing gear, and a lot of people are really happy about that.
Prior to Fox 'custom' manufacturing individual shocks for people with Enduros, you had the choice of paying Specialized around $800 for a link and the shock off the Evo.
If you wanna run a RS Vivid on your Enduro, now you can spend around $100 to be able to do so.
What's wrong with someone coming out with a cheaper alternative to that?
of course i just upgraded my old RP23 with the corset air can. damn.
(don't mistake me, @Vorsprungsuspension dudes, the corset is really awesome. but it can't improve the old rp23 more than a certain level)
I used full travel on the downhills of course and the bike is super stable and confidence inspiring. I don't see how slackening the front end out would help at all, in fact I think it would make it ride worse.
Is really the "main complaint" everyone you've talked to who owns these bikes? I have a 2010 enduro and the only complaint I can think of is it's a bit of tank to pedal up big mountains. I think it is a great bike, and I have a blast overtime I ride it.
@preston67 95% of E29 owners will disagree with you.
Furthermore, 90% of bike riders want to alter their bike for reasons that are unknown even to themselves. "Well, my buddy did it, so I need to keep up," or "It looks cool," or "Why should I let a bunch of engineers tell me what's good? I know I'm just a line cook at Chili's, but I think I know a bit or two about suspension design. I can read Wikipedia."
If you can't clearly define what is wrong (or right) with your suspension, then you shouldn't be touching it.
"Well, it just doesn't feel right," does not cut it. "What's sag?" does not cut it. If you think a 'spring curve' is the term for a hot chick in Lake Havasu, then you shouldn't get anywhere near considering altering your bike's stock setup.
The improvement is called choice.
And this is an obvious improvement over the fairly retarded OE design because of what JumboJack said. The rest of the original comment honestly has nothing to do with the product.
That´s why the Enduro 14 29 uses a standard 200x57 shock with our BikeYokes. Our Yokes are designed to have the same overall length (shock+yoke) as the original combination with the shock length, we define. And the stroke also is same as original (57 vs. 57). So you will have same travel and geometry.
You may check the compatibility chart and the shock lenght information here:
bikeyoke.mysimplestore.com/p/technical-information
However, it is also described in the product description itself, which shock you need for your bike with the correspnding Yoke.
Just look for your bike model in the shop and then click on the BikeYoke. Then you will see, that you need a 200x57 shock for your bike.
By the way: How can your CCDB on your Enduro be an off the shelf eye to eye shock with 216mm? How do you mount that to the original Yoke?
My buddy is running an X2 on his 27.5" Enduro and loves it like the hot step-sister he never had.
Of course they charge more, but IIRC it's not any more than this link costs anyway.
BUT, I will still always talk shit about the company
#f*ckspecialized
We´ll have a look at that. Thanks for the idea! If you have any more ideas, then just let us know. We´d love to realize any interesting ideas.
Talking to everyone...
Just contact us at sacki@crankingsolutions.com
That´s how this project started:

Go to shock sizes file...
We´ll just wait until the pre-order deal is over. Then we´ll go on with also taking orders for 13/14 EVO versions.
Taking pre-orders for them now would make it too complicated to communicate, handle and also cause delay for the shimpment of the other versions.
BUT: We already placed the orders for 13/14 EVOs to suppliers. So everythign is already set-up. Just need to be patinet for 10 more days then you can order. ;-)

Generally they do still live less rich then we do, but it's not like every single factory in Asia is a sweatshop and have terrible working circumstances as well as terrible wages (relatively to the costs in their country).
I am very much against sweatshops and know there are sadly way too many of them in Asia (as far as I know these are mainly in the clothing industry in China). From what I hear many welders in Taiwan are actually better at their job than most welders in America. The people at these factories generally need to have more specific skills than in the workers in factories that produce clothing. Since their level I expect they get trainings and education related to their jobs so they can produce the quality they do. Thereby these people are "worth" more to the factories and are less easily replaceable as you have to train and educate new people first if you'd kick the old ones out.
I could be wrong of course, but when speculating about factories in the cycling industry it would seem logical that the circumstances are better than in clothing factories.
It must be nice to shut down any intelligent thought process to cater to what makes you feel warm and fuzzy.

Have you been to Taiwan and seen factories there that produce for the bicycle industry? Yes? Well, of course you have. What else would you reply to that? And of course there are only seatshops, right? I have not seen a single one, weird...
I have lived in Taiwan for two years and I have seen hundreds of companies that produce the stuff we are all using on our bikes.
And please spare us the google thing. If you had been to Taiwan you´d know what´s going on there and then you would not bring on comments like that. Sorry, no offense!
Next question: Have you been in the factory (actually a small family-ran CNC company) that produces for us? No? That´s what I thought...
@Sacki Everyone I know uses the 650b yoke on their Enduro 29ers to fix the geometry. On my friends enduro 29er he has a CCDBair, and people on MTBR have been saying that the CCDB has just too much stroke and on bottom out the rear seatstay bridge contacts the seat tube. Do you have any experience with this? His shock is already the weird specialized mount; do you have any plans on making custom length yokes that still work with the specialized mount?
I think you may talk about this idea here:
dirtmountainbike.com/bike-reviews/trail-enduro-bikes/specialized-enduro-29-six-ways-three-wheels-sizes.html#lgrcLl5y12psIIxD.97
Please read this article with care. It is very poorly written and researched.
The numbers in there are defnielty wrong. Changes in angle and BB height are not possible as mentioned.
Just two examples:
1. Setup #3 and setup #6 must have the same head tube angle, since they only change the wheelsize. It is not possible to change angles, when you change the same wheelsize on the front and rear at the same time. Angles have to stay the same
2. Setup #2 and setup #3 share the same front wheel and the same fork. Setup #2 is said to have a HA of 66.5° at BB of 348, which is 10mm higher than setup #3 with 67°. This is not possible! If the front end is the same, then a slacker HA ALWAYS means that the BB has to be lower, too. It´s not possible to have a lower BB but a higher BB wiht same tire and fork!
There are many other reasons, that are not even possible in theory. I told them, when they pubulised this articel over a month ago, but no reply yet.
However:
Our Yoke basically has exactly the same difference in length as the orginal 650b vs. 29 Yoke. So it would also generate the same chang in head angle and BB as the original 650b Yoke.
But I still do not recommend to do that swap, since you can see on that one picture, that clearence between seatstay and seattube is really little at bottom out. Also please note, that on the picture they are using a coil shock, which can not reach full 57mm stroke. The bottoum out (foam/rubber) bumper on the shaft usually reduces the usable stroke of a coil shock usually by about 3-4mm.
So if you use an air shock, I can promise you, that your seatstay will hit the seattube for sure, when bottoming out.Also your frame has some amount of dynamic flex when bottoming out.
In my opinion this article is misleading and giving incorrect information making the use of a 650b Yoke in a 29er look like no problem.
I would not recommend to use the 650b link in a 29er Bike.
We are also not planning one with a little less difference in length at the moment.
Sorry to disappoint you, but I hope I could help you a little bit.

I would like to tell you so many things right now, but I am not willing to give you any platform here. You are a very rude person with a very ugly way of expressing yourself.
I am out, and I hope other people won´t reply either.
I take pride in that. Way to present no evidence in a counter argument besides personal attacks.
