Stumpjumper Flip Chip (2021 Alloy)

[@markparris6163]

Perfect ! I've had my S5 since last year and noticed more pedal strikes, simple to do and only took a few minutes. Need to test it now. Thanks

[@TXMTBN]

Awesome. Enjoy your ride!

[@wtfchazpwnt]

I have the exact same year, model, and size and I love it.

[@maccam26]

Actually flipped my chip without removing the top bolt on the shock and it worked very well, no frame kickback or anything. Thanks for your videos on the stumpy!

[@DUNEATV]

Your the only person on the internet/KZbin who explained this. Thx!

[@stephenjones4653]

HUGE thanks for this and the other Stumpjumper videos! Just got the same bike and this was the only thing that helped me out with the flip chip. The upgrade tips are really appreciated too - the brakes, cranks and paintwork are definitely this bike's biggest weaknesses.

[@johnbuntin7188]

Yes agree, brakes are the worse I've had on any bike. Very disappointed!

[@TXMTBN]

Links to information about the 2021 Alloy Specialized Stumpjumper (ie manuals, torque specs, flip chip) and all the tools I used in this video are all in the video description for you guys.

[@philipmiller6175]

Great video. Looking forward to changing to high position and seeing if the bike gets a little quicker in Jack Brooks corners. 😊

[@goosguardian76]

Dude, I really appreciate your video. It has so much great info. I use it as a reference for torque and tips assist on my new stump jumper! Great job!

[@teague091283]

Just bought a stump jumper alloy 2022 that comes in June , these videos are giving me a great insight on what to expect but also what I would likely b looking to upgrade 👌🏻👌🏻👌🏻

[@TXMTBN]

Congrats and thanks!

[@mechanicsofideas1392]

Can you post a video how change the rear shock.? And which going good that bike , I want get one with remote lock

[@jacobcroyle7758]

Great video and thanks for the spec link. I know that will come in handy. That's if the bike comes my initial deposit was 198 days ago, so I'm eagerly waiting its arrival.

[@TXMTBN]

I want to say that’s crazy, but I guess it sounds about right for what’s going on in the industry right now. Hope you get your hands on it soon!

[@LandonOchsner]

Just so people know, this doesn’t apply to 2019-2020 alloy Stumpjumpers. Those have still got the flip chip in the shock linkage. It’s weird that they moved it to the Horst link on the 21s when the carbon versions don’t even have a Horst link anymore.

[@ArtFerguson]

So what was different riding wise? I have a 2020 and flip chip is on shock. Felt like it lifted me up some. Less peddle strikes.

[@TXMTBN]

Most noticeable is fewer pedal strikes.

[@michaelnoah3795]

Great video! I just followed your instruction and changed my flip chip position. However, I realized that the bearing at the flip chip does not seems to rotate on either side. Is that normal, all my other bearings rotate very freely. Hope you can help me out, thanks

[@borispetrunov9917]

Great video! Thanks! I just picked my SJ from the local dealer ... I was wondering if there is a full lockout on the rear shock or it is just two option soft and hard?

[@dantharp8287]

Congrats! Not a lot of adjustability, it’s like trail or stiff. Have fun!

[@ChiodoDragon2]

New to the area coming from Houston. I'm down in SA but noticed your Comal Trails Alliance hat. Never heard of the organization but have some family up in Spring Branch so I'll definitely check out the trails up in Comal county. I'm currently using an old Rockhopper 29er but am wanting a full suspension. Do you recommend the Stumpy for this part of TX?

[@TXMTBN]

I do! Have fun out there.

[@ModGladBlock3.0]

Maaan thank you so much ive been looking for a video like this one Very educational and very helpful Thank you so much.

[@TXMTBN]

I’m glad you found it useful and thanks for watching!

[@brandoncollins3334]

Good video but you never mentioned what exactly you were changing. Going from low to high or high to low

[@GregBarfuss]

Why are you taking the rear shock loose? All you have too do is remove your rear wheel and remove the two Flip chips at the end of your frame turn them around and replace them.

[@connorplow]

You don't need to even take off the rear shock, I saw it in another video and did it on my Stumpjumper. 1st undue the wheel and 2nd change the two flip chips to the desired setting

[@TXMTBN]

Nice! Post the vid here would love to see that.

[@Mithrand9r]

Really helpful. Hopefully I’ll get my S5 delivered soon Do you think I should set it to high setting for more comfortable climbs?

[@TXMTBN]

Great to hear! Pretty easy to flip so you can experiment, which is fun. It will come set in the low position. Hope the bike comes in soon!

[@kobuskritzinger363]

Thanks for the video, could not find any other info... not even from the dealership. Can you pls confirm which way the bolt is facing for high and low setting? Bolt is currently further back.

[@TXMTBN]

Take a look at page 21 figure 7.1 in the manual linked to in the description. It will show you that the bolt hole nearer to the back of bike is the low position and bolt hole nearer the front of bike is in the high position.

[@grootjnr]

Hi love the video thanks for making it! Can ask a question please? WHen you remove the allen bolts from the flip chips, you hardly need any effort. Had you pre loosened them? I just started to follow your video just now on my 2021 stumpy and the bolts are MEGA tight. I mean, my allen wrench is bending. I can probabally force them with a longer lever. I guess they have factory fit locktight on the threads LOL Any tips?

[@TXMTBN]

I was using an Allen with a handle, so a little longer. Pretty tight first time breaking them as the have a bit of thread lock on them as I remember.

[@grootjnr]

@@TXMTBN Thanks for the reply. Yea I was using similar. That crack when they first loosen! Scary eh lol Keep up the videos about the Stumpy please, there are very few of us with the Alloy version that share info.

[@e-normmtb.8394]

Love your videos. Just picked up the same bike. Just wondering how you found the torque setting of 20.3 on the flip chip. The diagram in your link only shows 10 Nm torque setting on the Horst pivot bolt.

[@TXMTBN]

Thanks for the encouragement and congrats on the new bike. Check page 9 and let me know if I’m missing something.

[@e-normmtb.8394]

@@TXMTBN The only thing I noticed was that the link was for the carbon frame user manual. The link to the alloy user manual on page 21 shows 10Nm/ 90 in-lbf. At least that’s how I see it. ( I am new to this )

[@TXMTBN]

This one is the one that I indicate has the torque spec, think we might be looking at two different things. media.specialized.com/support/collateral/0000097877.pdf

[@e-normmtb.8394]

@@TXMTBN support.specialized.com/home/stumpjumper/manuals-tech-content This is what I found. It will show a stumpjumper carbon link and a stumpjumper alloy link.

[@TXMTBN]

This is great. When I did video I was working off the FSR version because the Alloy version was findable. I’ve update the link in the description and trimmed out the reference in the video (will take a little time to update).

Já když Chip přehazuji tak nedemontuji tlumič.Jde to i bez povolení tlumiče.A ty šrouby jsem pro jistotu zakápnul lepidlem na šrouby pro jistotu

[@fengcarlos]

I think there is a mistake on the geo, on the Specialized website says Stack (high) is 618 not 628, can you confirm that. By the way I followed this video for the flip chip and it works really good, super easy compare to other bikes. Thanks for the video.

[@SevenTwo5ive]

Thank you! What is the park tool that holds your axle called?

[@SevenTwo5ive]

Also do you know what exact park tool removes the bottom bracket?

@@TXMTBN thank you so much. also I really need help finding the right rear rim for my stumpjumper i bent my rim at snowshoe so i need to replace it but im having a really hard time finding just a rear wheel. Its a 29 6 bolt like normal. i still have the stock one on the front and id like them to match is possible. would you happen to know where i can order one from?

[@TXMTBN]

Eww. I haven’t researched this, but maybe a chance to upgrade the back and then follow later with a matching front upgrade.

[@austinaries2]

great video my only question is how do you know if your on hi or low?

[@TXMTBN]

Thanks Nick. It comes from factory in the low setting. The eye of the hex bolt will be closer to front of bike in the high position and closer to the back of the bike in low (factory position).

[@welkerfam]

What differences in the ride have noticed following the flip?

[@TXMTBN]

For me it was the bottom bracket being 7mm higher. I can’t say I’m a dialed in enough rider to feel anything else.

[@hro52518]

Dumb question but worth asking. Do you remove the air out of the rear shock before you unscrew it. Not sure if you mentioned it. can't wait to do this on mine. thanks very informative!

[@TXMTBN]

Nah, no need.

[@johnwicked4982]

is it possible to changed the wheel set from 29 to 27.5? Do i have to adjust the flip chip if i do the switching?

[@TXMTBN]

I guess you could, but I think you would get a lot of pedal strikes. The flip chip only changes the height by 7mm which is like the width of a pencil eraser, so not enough to go to 27.5s.

[@charlesonl5593]

Does the bike have it in high bb?

[@TXMTBN]

Could you ask another way? Want to be sure I understand the question.

[@TXMTBN]

Thanks. All the models come from the factory set to the LOW position.

[@aussierules3436]

Gone from a Nukeproof reactor to a new alloy stumpy as I cracked the frame and warranty yewwww

[@TXMTBN]

Nooooo!

[@unlimited408mike]

Does flipping the chip rize up the bike height

[@TXMTBN]

Yes by 7mm

[@brucesummers7448]

Changing frame angle may make a noticeably difference, though at 0.5 degree this is doubtful. Increasing the bottom brack height by 1/4 of an inch is also not going to make a real difference. If someone has problems with pedal strikes they need to work on their technique or put on shorter cranks or buy a different bike. But it is good marketing to provide this gimmic.

[@TXMTBN]

Agree

[@durgamayar4396]

Snowing in Texas? I thought Texas is always super hot :P

[@TXMTBN]

It’s crazy when it happens. We have no idea what to do : )

[@johnward_7199]

Notice much of a difference?

[@TXMTBN]

I’d love to hear from others on this and I’d love to say yes, but the only thing I can definitely tell a difference on is the bottom bracket height.

[@jon41302]

@@TXMTBN Awesome, I've got a Stumpy Alloy in NB as well. Wondering if you just flip the chip near the rear axle, or do you also have to flip something at the rear of the shock mount too?

[@geargabbers]

That’s a total coincidence! Just flip at the rear axle.

Can you replace 11 speed with 12 speed on stump jumper bike?
