- A quick video showing how to install the Redshift ShockStop Suspension Stem.
Please note that newer versions of the stems use a torx bolt in the wedge instead of the hex bolt you see in this video at 6:39.

I just need to say THANK YOU! I looked at the cryptic installation papers that came with my Redshift products and just saw question marks, and hoped for some sort of video tutorial. But this is one of the best-explained tutorials I have ever seen! I also really love your comments about what 1.5-2.5Nm feels like, that’s so easy to understand and useful! 🙌
Very good installation clip, the stem sure works well for shock absorbtion.
@littlefish4270 glad you found the video helpful and very happy that the stem is working so well for you.
I just fitted one to my steel-framed Trek 520 touring bike. The difference is astonishing. Prior to fitting the bike would give me huge hand and shoulder pains. It was so bad I thought my teeth were going to fall out on some road trips. Very unenjoyable. After fitting the bike is an absolute joy. It has basically erased fatigue. Cannot recommend it highly enough
I have Multiple Sclerosis and this stem is game changer for me. My nerves don’t take such a beating anymore!!!!!!!
Thank you for these informative directions. Made installation very easy. Path Less Pedaled for giving a great review and their discount for being their Patreon member. Loving the stem on my steel hobobootleg railway bike.
This company’s customer service is absolutely amazing.
Thanks for the support, Jerry!
Just bought mine. I have a multiple ruptured tendons in shoulder & hope this will help to remove the vibrations in our poorly maintained roads.
Good video
I'm waiting for mine. Great information. Thanks a lot.
Thanks for this. Excellent. Installing mine tomorrow. I don't think this is a "quick video" though 😆 I'd call it a thorough video.
Thanks for excellent delivery by Amazon just got mine today and i ordered it on Friday afternoon so you guys are absolutely amazing and i live in London lol ..thanks and thanks for incredibly clear video and instructions and also the instructions with the leaflet provided in the box with your excellent product which i will fit to my 12 year old Marin Novato Urban bicycle ..Cant wait to ride thanks guys for everything
I just installed the shock stop stem using this video. The only tricky bit was reinstalling the preload wedge as it took some force to get the screw aligned. Other than that: the stem combined with the seat post from Redshift are brilliant.
Great video - Steven is an excellent presenter and always covers questions you didn't know you had. Redshift does a great job with these. Thank you!
Thanks so much Peter - really appreciate the awesome feedback and so glad the video was helpful!
@@Redshiftsports Hello. I didnt understand the instructions. I have a height of 186 centimeters, weight 81 kilograms. What plastic parts do I need to install inside the takeaway?
Installed mine yesterday. No issues. Many thanks.
Happy to hear it! Enjoy the stem and thank you so much for the support, Bob!
I just installed my Shockstop Stem on my Priority 600 and it’s excellent. This thing really works, it takes the trail chatter out of the bars and is so much more comfortable and smooth, it really is excellent. I decided to install the elastomers for one weight class higher than me as I didn’t want too much movement in the bars and I like how the bike feels. The elastomers should get a bit softer after a few rides and I may re-adjust depending on if they get too soft. Follows the instructions, watch the video and go ride.
Very complete......Thank You
Exceptionally done video!!
Keep it up 😉
Thank you the video very helpful
excellent vid
Thanks for the support, David!
What a well documented and engendered product, I was impressed before even riding it. That’s what you get when you deal with cyclists! 😊
Thanks so much for the kind words - hope you really enjoy the stem!
Thanks for the video, reading the instruction had given me a little bit of anxiety but it now it seems quite simple. Would you recommend blue loctite for a light gravel use?
Just received mine today, getting ready to set it up. Instead of a beautiful box mine was in a plastic bag that allowed it to get some minor scratches but I get that that's a first world problem. Hoping this thing is as good as it looks.
Hi Mike, thanks for bringing this to our attention. That is not how the Stem should have arrived. I really do apologize for that. Would you mind reaching out to support@redshiftsports.com? I'd like to make sure that you received all your parts and help out where we can. We can certainly get this replaced for you!
@@Redshiftsports That's awesome, and why I love dealing with smaller companies! I'll get you an email tomorrow, thanks!
You're more than welcome, Mike! Thanks for the support and looking forward to your email.
I would like you know what torque wrench you are using.
Would be helpful to review the other elastomers and what combinations to use
Great feedback - if you check out the instructions tab on the shockstop product page you can see a full rundown of elastomer combinations and how they relate to each other: cdn.shopify.com/s/files/1/0089/1220/7951/files/Elastomer_Chart_Expanded.png?v=1618086180
I was taught NOT to use a torque wrench as a ratchet. I use a "T" style allen wrench.
You have a red thingy on the latest stem. Could please make a video on that. Tnx
Next purchase for my off road touring bike... question ? do you get all elastomers ( for all settings) unlike my G4 LT seapost as that adds extra expense !
Yes! You receive all 5 elastomers (2 pre-installed in the stem, and 3 more in the box) to allow you to customize the suspension feel to your liking.
Hi, just fitted the stem following this excellent video. But I switched elastomers and when I put the preloaded back in it has moved the elastomer from the vertical position, is this normal?
Thanks for reaching out! I believe we just responded to your recent email with a few images. That should answer your question but essentially it is perfectly normal to see elastomers 'deform' as you are installing the preload wedge. Let us know if you haven't received our email response. It could have gone to your spam. Thanks!
I bought this and just now saw the warning about swept back bars. I have a Kona HAND Plant cruiser bars on my ebike which have a mild sweep. Would this be compatible with those bars? I really love the seatpost and want this to work so bad!
Hi Benjamin, sorry that it wasn't more clear about the Shockstop not working as well with swept-back bars. That being said, it does depend a lot on the length of stem you purchased and the amount of sweep in the bars. Why don't you reach out to support@redshiftsports.com, we'd be happy to discuss this further and see if there are any options for you!
I just got the new ShockStop stem and it has the new install and removal tool for the rubber elastomers. Do you have a video for the use of that?

@@Redshiftsports thanks.
I'm thinking about ordering the stem and seat post.
I have a question about the stem, how well does it with suspension forks on my hybrid.
Hi Zeeb - the stem and post will work well on a bike that has a suspension fork. For the stem in particular, it is pretty complimentary if you set it up to deal with the high frequency wide of things. Obviously, the travel is very small compared to a typical suspension fork but it will add to the overall suspension feel of the bike. Thanks
Is there an elastomer #1 and #2 position.....I mean, does it matter if #1 is installed on left or right ?
Not an engineer and just installed mine but: probably not. Orientation and position for both is crucial, which is where doesn’t matter.
@p0ddie this is confusing as the instructions refer to elastomer 1 and 2 with different combinations, eg 70/60 1 and 2 combination for lighter riders than 80/50 1 and 2 combination for heavier riders.. but the totals are the same, so surely knowing what is position 1 and 2 is critical?
Same question, noticed in video he installed higher numbered elastomer on the left side when looking into the stem from in front of the bike, so I guess I'll try that way just in case it matters.
I just installed this stem and suspension work fine. But I found another problem, my flat bar shake right and left, I've tightened the pivot bolt but still no change. What should I do? Thanks
Hi Eko, thanks for bringing this to our attention but sorry for the trouble. Would you mind reaching out to our support@redshiftsports.com email? The team over will be able to help get this resolved for you. Thanks!
I just stripped my preload wedge bolt. Has anyone had this problem and found a way to get the bolt out? Or after the elastomers wear down, is the stem done? Thanks.
Hi Arthur, sorry that the bolt stripped but don't worry, we can certainly help get this figure out. I just receive your email as well so I will follow up with some solutions shortly. Thanks!
The stems come in two different lenghts 80 and 100 mm, each of them can be used in two positive positions +6 degree and + 30 degree (negatives are not for me). Is there any difference in effectiveness between +6 and +30 degree?
Hi @Marke-bv6lf - the stem actually comes in a number of lengths/angles: we have the +/-6 deg which is setup to default to +6 and that comes in 80, 90, 100, 110, and 120mm and then the +30 deg comes in the 80 and 100mm lengths. The +6 versus the +30 is only a matter of how you want your handlebar setup and the stem is just as effective in both orientations. If you have any additional questions the best way to reach us is to email our tech support at support@redshiftsports.com - thanks
His instructions regarding that the top of stem should be 2-3 mm above top of steerer tube seems inconsistent with written instructions that “the top headset spacer (or top of the stem if all spacers are positioned below the stem) is slightly above the type of the steerer tube.” My steerer tube is slightly higher than top of steerer tube, but I have two spacers between stem and top tube cap for a 2-3 mm space between cap and the top of stem. Is that acceptable?
Hi David - you have done it correctly and sorry for any confusion. As long as there is space between the top cap and the top of the steerer (either the stem clamp is above or spacers are slightly above) you are doing it right and will have things correctly setup. If you have any additional questions or need anything you can always email us at support@redshiftsports.com - thanks
Is this stem compatible with the giant hydrolic brake stem system, what are the spaces between the bolts
Hi Andrew - Unfortunately, the Giant Conduct stem faceplate has a different bolt pattern than the ShockStop Stem. The conduct faceplate has bolts that are 40mm apart vertically and 22mm apart horizontally whereas the ShockStop has the bolts 32mm apart horizontally. So, the conduct faceplate will not mount to the ShockStop stem - but we have had a few customers who have opted to remove the conduct faceplate and have the brakes changed at their local bike shop. So, if you really do want the stem this is a possibility and you can talk with your bike shop to see what it will entail. Thanks!
Please develop a model for Brompton.
Many many Brompton riders are suffering from wrist pain.
I think it is not difficult.
Modification of connection between column of brompton and suspension system is enough, considering length and position for folding.
Bromptons don't have stems so I don't see how this would be possible. The bend in the handlebar serves to flex a little bit. I find the P-bars to have the most flex followed by the M. Try changing to Ergon grips with the wing if you don't have them already.

Might want to include the need to go back and tighten the wedge after a "busy" gravel ride...I cant imagine using locktite on the screw though
Hi Robert - thanks so much for the great feedback. Regarding loctite you can definitely use that on the wedge bolt if you are looking for a semi-permanent hold just select something that is a step below permanent. Thanks
How durable are the elastomers? Does it make sense to purchase an auxiliary set with the stem?
Hi @Marek-bv6lf - the elastomers are super durable. You do not need to get any spares. In fact, I think the only elastomers we have replaced are ones that get misplaced. The stem is designed such that it never compresses the elastomers beyond a safe level and the material we use is very robust and holds up really well. We have many many riders who are using the same elastomers since 2016. Thanks
Instructions say to apply down force to remove wedge which you didn't?
Which elastomers do i used for heaviest riders on paper says 60&50 which to me makes no sense whent it comes with 70,80&90 options
HI Juan - thanks for the question. If you are using the stem with a flat bar then using the 50/60 combo is pretty stiff. But you are right you could make the stem even more stiff going all the way to 80/90 but with a flat bar that is pretty much rigid. Most flat bar riders will be using a single elastomer which is why you don't see the bigger combos called out for a flat bar. For a drop bar you can see in the chart that the stiffest combo is 80/90. Hope that helps and if you have any additional questions feel free to email us at support@redshiftsports.com and we can help you out!
What torque wrench are you using?
I believe we used a Tekton Torque wrench but any high quality torque wrench will work. Thanks for the interest!
Hi there, 2 questions:
1: In the video the elastomers are below the preload wedge at first. Referring to the manual, the elastomers need to be always above the preload wedge, regarding if the stem is mounted in +/- 6° - super confusing.
2: Out of factory, the elestomers/stem is shipped in +6° for a rider weight between 135-155lbs, if that fits for me, is it save to just install the stem without touching the preload wedge/bolt/elastomers?
Thanks and thanks for the great product!
You are correct that the elastomers always need to be in the top - and good eyes noticing they were on the bottom at first - that was because we installed in the -6 deg and needed to swap them from default.
The stem is ready to ride out of the box and we actually recommend everyone give it a try if they want the +6 deg orientation and see how it feels and then adjust from there. Thanks
@@Redshiftsports
Thanks for the fast reply - after rewatching the video and listing carefully, i noticed why it was kinda "flipped" first.
Had my first ride yesterday and it was a blast!
Cheers
@@honkx so glad the stem is feeling good!
Is a torque wrench required for proper installation?
We highly recommend using a torque wrench to get all the bolts tightened to the exact tightness specified in the instructions and on the products.
Is it safe hide an AirTag in the open space in the stem body?
Great question. I would be cautious because the mechanism for the suspension is inside the stem body so if you didn't secure the tag to a spot that was not touching anything else it might get damaged - and if it got loose it would almost certainly get caught in something and might damage the stem and the tag. Thanks
Why only 1 elastometer for flat bars, what would happen if you use two?
Since flat bars don't have the same leverage that drop bars do, the stem doesn't require as much resistance. If you used two elastomers, you might not notice the suspension travel.
Can anyone tell me what be wrong or have to be done? I just installed this but it's not doing any movement up or down
Hi Tom - shoot us an email to support@redshiftsports.com and we can help you get it sorted out. If you have a +/- 6 deg stem if you happened to flip it to run in the -6 deg orientation you do need to flip the elastomers inside (as indicated in the instructions) but there could be other reasons as well that you are not feeling any motion and we can definitely help you get it sorted out right away. Thanks!
Can I use this with a carbon steerer tube?
Yes, you can use the stem with a carbon steerer tube. Make sure to in follow the torque specs and consult your frame manufacturers instructions as well.
Can you install 2 utility mounts safely?
Hi Jeffery - thank you for checking the Stem out! You can certainly use 2 utility mounts safely on the Shockstop Stem! We have also seen customers use our Computer mount in the upper position and the utility mount in the lower. Take care!
I don’t know if I want the +/- 6° or the 30° one. Help?!
Thanks for reaching out StephanRay - ultimately it depends on what kind of riding position you are looking for. The +/-6 deg stem is a more suited for someone who wants a neutral stem angle and a more aggressive race type setup while the +30 is perfect for someone who wants to have a more upright type riding position. Hope that help and if you have any additional questions please don't hesitate to email us at support@redshiftsports.com - thanks
The bolt that secures the wedge comes with a small silver screw do you need to fix it with the large black bolt that comes with the pack ??
Many thanks
Hi there - I am guessing you have the 80mm version which includes a 2nd tool for installing the wedge - this tool is used to seat the wedge in place and then it is secured with the silver bolt and the install tool is removed. If you visit our website you can find instructions and videos for the 80mm version (there is also a link at the beginning of this video). And if you have any questions you can always email us at support@redshiftsports.com
@@Redshiftsports many thanks
👍👍
do you do a spare silver bolt for the 80mm stem ?
@@addiecusack1530 yes, please email us at support@redshiftsports.com and we can help you with that and any other spare parts you might need. Thanks!
@@Redshiftsports you guys have been brilliant .
Your service is outstanding well done to all involved 👍👍
So glad to hear that it worked out! Thanks so much for the kind words!
if only my mechanic worked this fast since he charges $80 an hour :p
I had no success with installation. My model is a 110mm one, used in +6° position. I am trying to put it on a flatbar handlebar (hybrid bike), using a single 70kg (blue) elastomer. I weight 92 kg. I found no problems in insering the elastomer into one of the upper slots while pulling the stem up. I made sure I did push it to the bottom of the slot. Thereafter I insert back the wedge and start screwing it back while keeping downward pressure. The issue is that I reach 2.0 Nm torque only after about 10 turns, and not about 30 as expected. I am afraid to apply more torque and damage the thread. Assembling everything back using such torque ends by leaving the handlebar loose, with no resistance at all to vertical movement. I suspect using another elastomer will make no difference, since the issue seems to be the absence of precompression. I believe I reached 2 Nm by only countering the thread resistance, before even starting to compress the elastomer. I would appreciate hints on how to proceed here.
Hi Mario, sorry for the trouble here but don't worry we can get this worked our fo you. Do you think you can actually send this over to our suppor@redshiftsports.com email? It will be easier to walk through various solutions and get this resolved for you through email. Thanks again for bringing this to our attention and don't worry we'll be able to get this working for you.
Can you set the stem at 35degree angle
Thanks for the interest! The Shockstop Stem is not adjustable but we do have two angle options, +-6-degrees and +30-degrees! It sounds like our +30 degree could be a workable option for you. It comes in two different lengths, 80mm and 100mm. Check it out here: redshiftsports.com/products/shockstop-suspension-stem
Hmm - just bought and this does not fit on the headset for my Canyon. Looks to be 1-2mm short to fit. Anyone else come across this?
Hi Stuart - it is possible that you are trying to install the 1-1/8" steerer tube version on your canyon which has a 1-1/4" steerer tube diameter. We have a version of the stem that will fit your canyon so if that is the issue please reach out to us at support@redshiftsports.com and we can help you do an exchange. Thanks!
Good explaining, very low volume, please raise the volume.
Hallo ! Brend and model saddle please?
Thanks for the question - the saddle is made by Adamo but it is a pretty old model of their split nose triathlon saddles so best to check them out and see what the latest models are. Thanks
لماذا لا يتوفر ترجمة عربي
Why there is no Arabic translation
why not provide equal amt of elastomers it we use 2?
Great question! To answer that it would probably be easier to send you over to this FAQ on our website: redshiftsports.freshdesk.com/en/support/solutions/articles/9000150208-why-not-two-elastomers-of-the-same-stiffness-
@@Redshiftsports thanks that makes sense maybe car suspension tuning can use that logic
You're welcome and that is a great point, Ming!
Max bar sweep?
Thanks for the interest! That is somewhat dependent on the length and angle of the stem you choose but in general, if the area where you grip the bars is level with or behind the pivot, you won't feel as much travel. Drop bars and flat bars work great but there can be some incompatibility issues with "cruiser-style" bars that have an excessive amount of rearward sweep.
My bike has a +7 degree stem (touring bike). Will the 6 degree stem be ok or do you provide one at a steeper angle?
Hey, that should be no problem. The difference is so small you probably won't even notice it.
By the way, I just bought and installed mine today and it feels great!
@@tuomasd I just ordered one. Looking forward to the experience. I take it you're happy with the change?
@@darrenprior6339 Yea, after my initial test ride I'm sold! Although the suspension travel is quite small, it really takes off the edge from cobblestobes, protruding tree roots, rocks and all kinds of small bunps. It also doesn't flex too much that it would feel sluggish when sprinting out of the saddle. I installed it on my gravel bike that I use for bikepacking. I believe it will increase comfort considerably during long days in the saddle.
I hope you will be happy with yours!
@@tuomasd Good to hear. Cheers
Nice video. However is this Specialized bike already equipped with the Future Shock dampener?
This is an older Specialized Roubaix that came out before they started equipping them with the future shock.
Very helpful, thanks. Next video, could someone please turn down that transistor radio in the background?
It’s not a 3mm Allen wrench but a 2.5 torx for elastomer. Almost drove me to drink. Well after all done I notice the included torx wrench, lol. Still the video is wrong saying 3mm.
Hello - you are right and sorry for any confusion. We made a change to a torx bolt a couple years ago which is a while after this video was put up. All the best!
Hey it’s all good. Love the product. Ordered a second one for another bike. Just curious why you switched to torx from 3mm. Seems a thing now. Liked it better when all bike stuff was hex.
@@sdanjohn glad you are loving the product and ordered a 2nd one! The switch to torx was actually just practical - we were trying to do as much as we could to ensure that it was hard to strip the internal wedge bolt - on the whole hex is a little easier to strip so we made the change and included a tool to make sure everyone had the right one. Thanks again for the feedback
U skip the elastomer bracket removal part
Hi @shaifulothman7442 - if you go to 6:37 in the video you will see the discussion on removing the preload wedge. Please note that for newer stems the bolt is a torx not a hex and you can see this in the instructions that came with your stem. Hope that helps but if you have any additional questions you can email us at support@redshiftsports.com - thanks
Sorry, but I found that the way your voice faded at the end of sentences, made it difficult for me to hear what you said.
Sorry for that Brian. If you have any questions on installation feel free to shoot over an email to support@redshiftsports.com. Thanks for your interest!
Turn on closed captioning.
They have changed the stem, this did not help.
Sorry that you had trouble with these instructions. We added an 80mm version that has a different elastomer install and removal process but that video is linked inside this one so sorry that you did not see that. Here it is: ruclips.net/video/TRIt8zyUYvY/видео.html
now i know what a dad bod is
I've watched this and I'm non the wiser... As an instructional video is fairly poor, the camera should of been pointing inside the stem when you was working on the elastomers
Good info, but this could easily be a 3 or 4 minute video way too long. Likely poorly scripted/planning. Can be improved
Great suggestion! We'll look at cutting this down to be a little more digestible. Thanks for the interest and support!
