Thanks for taking an interest in these "special" components that Specialized bakes into their bikes. Beyond the FS I was most surprised on how they ran away from the boost wheels. They included a frame setup with unique for a road bike. In virtually no time after the second Creo was introduced you were no longer able to upgrade or replace the boost wheels. Thanks again for the work you put into this. Really enjoy your videos.
I’ve just switched out the FS 1.5 to the FSD slammer and the difference in ride quality for me as a road rider is night and day! The front end feels both stiffer, lighter and the bike is far more responsive when climbing, cornering and putting the power down. I haven’t gotten on with the FS for a while now and this was my last attempt to try and rectify this or just get a new bike. My Roubaix has pretty much been converted into a Tarmac and feels like a new bike! Thank you so much for engineering this amazing solution for those who don’t get on with the FS technology and saving me the cost of a new bike. Delivery to the UK was quick and it’s worth paying the extra for a decent product like this vs some other options which I thoroughly researched.
I'd just like to second what has been said here. My 2019 FS had become saggy even after swapping out the spring and I didn't want to spend the money on a replacement. This is a fantastic option.
I just saw the first trial to delete the FS that failed in a race, don't remember the racer... But I remember when working at the shop and milling a similar part to adapt due to difference in diameter, how it failed at the first push due to the effect of 90° angles at the steps where diameter changes, never tough that could happen so easy, I hope the aluminum does not suffer that effect too... At that time we had to mill the piece with curved transition to avoid that fail
Stress concentrations are always highest at sharp corners. Ours uses rounded corners and a slopped transition on the inner diameter to avoid this weakness. Also we use 7075 T6 which is much stronger than typical 6061. Can you point me to the design that failed in a race? Haven’t seen that
Great item, would love to try out one. What about if there would be possibility to delete the fs and also have integrated cables? Because my roubaix 2020 is a mess upfront.
I agree. An integrated version with a notch in the top, much like @twistedwheels did with his is CRUX build. or take to machine shop and have the material removed post purchase.
Maybe because you wanted one and don't anymore? Or you really needed a roubaix for the riding you were doing and don't anymore. Plenty of people do rear suspension deletes on full suspension mountain bikes. This isn't too different than that.
@@veganpotterthevegan Thats a strange one, i have been mountain biking and racing since the early 90’s and never heard of anybody doing a rear suspension delete in all that time. 🤔
Any plans to sell the shorter duckbill, or do you know where one is available? I'm not sure a shorter one came with my Roubaix (or I lost it) and I can't seem to find the shorter one online. I'm planning on ordering this, but I'd like to have the shorter cover before I do.
You can get a lot of FS parts at Performance bike. The short duck bill is like $15. www.performancebike.com/specialized-future-shock-headset-top-cover-black-0mm-stack-s192500011/p1535703?v=1142855
The Slammer insert uses any standard 1 1/8 stem. If you have a Roubaix with Future shock, it's possible you have a "future stem," which has a smaller clamp diameter. This stem will work with our standard FSD kit, but the Slammer version is designed to use a standard stem.
Man this future shock thing is a mess. Crazy to have to create such an intricate solution to what should be a pretty basic steerer tube. Genuinely curious, does anyone who owns one of these frames with the FS actually like it?
To be honest, the ride feel when it's new is remarkably good. The problem for me is that its such a complex system and both of mine eventually started making creaking and popping noises. The cartridge is not serviceable and the official recommendation is to replace it.
I've got two '21 Diverges. One with FS 1.5 and the other with 2.0. I don't have a problem with either and appreciate that they take the edge off big hits.
I have a Domane. But I'd love to have a Domane with a future shock IF I could have a very slammed stem. I've borrowed one and loved it but the geometry just didn't work for me.
So far loving mine. It is not an intricate solution. For that go look at MTB forks. This is vastly more simple. The problem is that it needs more adjustability because people ride with different weight put upon the handlebars. I have the FS2 and think that while it adjusts dampening it is limited in not allowing adjustment of the springs. For me it is pretty good at its lowest damping setting. Which makes me wonder if FS1.5 would not be an improvement.
I never liked Specialized until I rode the Roubaix I bought my late wife. With carpal tunnel syndrome I was surprised at how much the FS helped, yet the bike's stiff enough to rival my hardcore race bike. It's one size too small so I found an S-Works frame in my size and swapped the components over, and it's by far my favorite bike. I want to buy a Diverge to replace my CX bike but can't find a decent deal.
Pull a future shock headset assembly apart and you’ll see what I mean. The fork steerer is a different diameter and the preload system is lower in the system. An Ahead style 1 1/8 headset won’t work. Otherwise people would have swapped the fork already.
It's kind of surprising that specialized bike doesn't offer a delete kit themselves, since some folks might want to switch out the cartridge between road rides and rough gravel rides. Kind of like having two dedicated wheelsets on the same frame.

Glad it’s working out for you!

This is in the realm of, I didn't know I needed that. But I've definitely pre-ordered because I need it.
I was thinking of replacing my fs2 and wanted to slam it. You might have addressed my issues with one solution.
You’re not the only one!
A slammed Roubaix is even more aggressive than a Tarmac SL7. I machined my own replacement earlier and found that I had to use high headset cover 😂
Haha did not know that. I recall the roubaix being pretty upright. I guess it’s changed a lot since my old SL4 😆
like to see add suspension stem on the future shock, must be fun to test it out
Haha a viewer tried it and said it feels really wonky and disconnected

We need an answer on this!!!!!🎉
What is keeping you from installing a 'standard' fork in it ?
Great item, would love to try out one.

I agree. An integrated version with a notch in the top, much like @twistedwheels did with his is CRUX build. or take to machine shop and have the material removed post purchase.
Would love to see a version with internal wiring
7075 T6 may be prone to stress corrosion cracking (SCC). Would 7075 T7 be a better choice
I don't want to change the geometry of my Sirrus X 4.0 (w/OEM flat bar) so, should I'm guessing I should get the original FSD kit? (tia)
Yes, the original FSD kit is a direct replacement.
Sold out. Will there be a restock?
Why have a roubaix if you are going to get rid of the Futureshock. I love mine and recently had an exchange one on my 2020 bike.

@carltonholmes8061 it's a big enough thing that there are delete kits vs jerryrigging them
You could have two treaded tube instead of the cartridge and have a ring on top to adjust height on the fly? Wouldn't that be possible, just asking?
Interesting idea. Cost would certainly go up and reliability might go down.
Clever!

What stem would you recommend using with it? You said it can’t be used with the factory one on the roubaix right?

So do you need to use the shorter "duckbill" or can you still use the taller one?
You can use either duck bill
Wish they where available in the UK
We ship worldwide. Shipping cost is pretty high, but a good 20% of our orders are outside of the US

Why not put a Tarmac fork and bar on it????
Future Shock equipped bikes use a proprietary fork and headset.
@@TheBikeSauce they are both 1 1/8th
Pull a future shock headset assembly apart and you’ll see what I mean. The fork steerer is a different diameter and the preload system is lower in the system. An Ahead style 1 1/8 headset won’t work. Otherwise people would have swapped the fork already.
@@TheBikeSauce that is super stupid for Specialized to do that!
Hey, that's cool.

100% agree.
