Road Cycling “It is by riding a bicycle that you learn the contours of a country best, since you have to sweat up the hills and coast down them. Thus you remember them as they actually are, while in a motor car only a high hill impresses you, and you have no such accurate remembrance of country you have driven through as you gain by riding a bicycle.” -- Ernest Hemingway

True, but a massive amount more riders choose full suspension bikes with huge gear ranges. Look no further than the wide selection of bikes from XC to Trail to DH and everything between. The number of SS rigid bikes sold today are miniscule by comparison.

I propose that the modern stems used in the gravel arena will prove more popular than the older attempts in the MTB world. Once we get past the old memories of less than perfect models in the past (and the stigma associated with a new/old item like this) I expect these to become a standard on many bikes.

Remember how long it took for suspension or disc brakes to get fully accepted in the MTB world?

CX is only mildly relevant here since they focus on huge pain for short bursts (45 mins or less usually). So comfort is far from a concern when those riders are struggling to see straight and not blow up their heart.

Comfort is much more of an issue when you ride 50-200 miles (3-15+ hours) on the bike over less than smooth roads (aka gravel grinding).

If a body adjustment is all that is needed, please explain the large push by riders to move to ever larger width tires for gravel. They have moved past the "simple" 700 x 45c size on to 650b x 47 for road-plus use. All of this is a search for more comfort on rough gravel roads.

Add to that bike makers working to add compliance by various methods for the broadening range of dedicated gravel bikes.

All that is to say, I thin the new stem (and bikes like the updated Diverge) will see a wider popularity as people get over their hangups.

Manliness discussions aside, I'm officially intrigued by these stems and will look into getting one for my bike.

Do it. After your pocketbook recovers, you will absolutely love it. Mine is staying on my bike forever.

I don't see why not. As long as you don't exceed torque specs for the steerer. Contact the manufacturer if you are uncertain.

I emailed them, since it didn't say explicitly. Waiting for a response. I'm sure it is, but I want to make sure. (I have a Domane, and Trek makes a big thing out of using trek stems only on their carbon steerers, but that aside, I want to make sure.)

Does Trek make it a big enough thing to say that their bike will fall out of warranty using another brand of stem?

Doesn't say anywhere I can find, actually. I thought I heard it someplace on the web, but now can't find it.

They do say this:

2 years
Session (carbon) model frames and swing arms
RIDE+ motor, controller, & battery pack (or 600 charges, whichever comes first)
All original Bontrager forks, parts and components (except consumables such as tires and tubes)

I'm beyond two years on the bike, either way.

I ordered my ShockStop today. Even got a 15% off coupon for signing up for the newsletter! Really looking forward to trying it out.

Shock stop arrived today! I'll do a mini-review after I've spent some time with it.

Just because it was bad in one place, does not make it bad everywhere. That misconception is rampant an on display in nearly every post I have seen on this new stem.

Not great for MTB, much more suited to shorter travel use on roadies, gravel, adventure, etc.

I used the TranzX shock reduction stem for a 252-mile, three-day fundraiser recently (A Ride to Remember from Simpsonville to Charleston) and I found that it was barely perceptible in comfort increase compared to a fully rigid stem, certainly not worth the increase in weight or the cost of the stem (and I bought it for a reasonable price from SJS). Just replaced the TranzX with RedShift's ShockStop and the difference is immediate and immense--there is no comparison, as the ShockStop is much, much more comfortable, not to mention better looking, than the TranzX. That being said, if you are a weight weenie, stay away from either product, but if you value comfort (and by extension, improved endurance/reduced fatigue on long rides), the RedShift ShockStop is the best front vibration damping device I've tested.

I also have the Extraordinary Microscience GripFast shock absorbing stem riser on a different bike. For the most part, I cannot recommend that product nearly as much as I could RedShift's ShockStop. The ShockStop is a well-thought-out, well-engineered, quality product that functions well for its purposes; the GripFast is far less refined, as it is designed around a preloaded coil spring, so bumps that do not exceed a certain amount of force won't activate it (and it is not tune-able/adjustable), and those forces sufficient to activated it result in the device absorbing the initial shock by compressing, but then creating an uncomfortable reaction when it decompresses back to neutral position with a hard clang--there is clearly no form of damping or soft stopping for it. In theory, the device has a geometric advantage versus the other two products in that the angle of the bars does not change throughout the travel of the damper, but the problem is the lack of refinement in how it rebounds back to neutral position.

At this point, my intention is to mount the TranzX shock absorbing stem onto the bike with the Extraordinary Microscience GripFast, so as to test and see if the TranzX stem can help smooth out rebound to stop motion of the GripFast, and create some sort of a more refined combined system, but at the end of the day, a single RedShift ShockStop would be the far superior solution, in my own experience!

To note: I am using the ShockStop just fine on a bike with full carbon fork & steerer, but I do make sure to use a proper torque wrench for all of my installs, and the 5nm that the RedShift ShockStop specifies is well within safe parameters for the carbon steerer on my bike. I am also using an Ergon CF3 seatpost in conjunction on this bike--I love my Ergon CF3!!!

The Raleigh I just bought apparently comes with both a TranzX stem and post. I'm suddenly keen to try them out. The original plan was just to fit a 35c tire up front and carbon bars. Perhaps the +120g of the ShockStop isn't so bad relative to the same on a tire.

I can already vouch for the efficacy of the Ergon seatpost. IMO, aerodynamics aside and given that acceptable knockoffs come in at around $40, there's no reason to buy anything else. It allows me to run an unpadded carbon seat and stay in the saddle on sidewalks and wood bridges with no weight penalty.

So I finally have some mileage on my shock stop, and I have to say IT'S AWESOME. I have the bumpers set to what the manufacturer says is correct for my body weight, but I'm thinking I might go one level stiffer after I've put more time on it.

Mini review:

It's beautifully made, and clearly a quality piece of gear. Robust and well made, and of quality materials. My only real objection to it is that it's a little boxy, visually, but given the need to be able to get the elastomomers in and out, there's not really any way around that.

Install:
So, first, it comes set up to be used as a +6 rise, whereas I'm running it -6 (It's replacing a -7 Bontrager stem.) Mounting it to the steerer was no different than any other stem, and in spite of the supposed fiddliness of swapping the elastomers as described in some of the reviews, it really wasn't a big deal. The only real reason to attach it to the steerer before doing an elastomer swap is to allow you to get enough pressure on the elastomers to thread the retaining screw straight and not cross-thread it or strip the initial threads. (It's under some tension as a preload.) All that took no time at all, and I was ready to ride!

When you're standing over the bike, bouncing the handlebars--lol--the flex is pretty prominent--I was surprised, actually. it felt quite soft--but once you're on the bike, you rapidly forget about it entirely.

Ride:
One word: AMAZING. When I first went out with it, I did noticed the motion of the bars. Not remarkably, but still, it was there. A mile or so in, I had forgotten about it, and found myself unconsciously "preparing" myself when I saw rougher or broken pavement coming up....and then just floated over it! (For the first half hour or so, I kept being surprised by that.)

Note: You still get plenty of road feel and road buzz coming through, so it doesn't feel numb, just much smoother than normal. It really does make rough pavement feel like smooth pavement! It doesn't jiggle or vibrate or otherwise respond in an uncontrolled fashion to impacts or vibrations; it feels really well damped.

Someone else said they noticed the motion of the bars when climbing, but I didn't at all, but I don't spend a lot of time standing, and when I do, I'm usually at the point where I'm just trying to get up the hill without having a heart attack. The only time I do noticed the motion of the bars is when I'm at a stop...bouncing on the bars because of the novelty of it.

Now, as I said above, I'm going to experiment with moving up to stiffer elastomers just to see what it's like, but I would be perfectly happy with the current elastomers, if that wasn't an option.

Summary:
I think the ShockStop is a fabulous product! Well made, well designed and thought out, well executed. I got mine with a 10% off coupon, so I was really excited to get it somewhat more cheaply, but even at list, I think it's well priced.

It's really beautifully thought out. And I love the simplicity of the concept as compared to, say, the more complex Specialized Future shock, or even the Domane SLR's front leaf spring. Incredibly simple and robust, and feels like it will last well.

If you have problems with sensitive hands and wrists--as I do--or simply live where there's a lot of crap pavement, I highly recommend the ShockStop!

good review and I concur. I’ve got a couple thousand miles on mine and it’s not going anywhere. Definitely takes the edge off on washboard gravel, but otherwise I don’t really notice it’s on my bike. To me, that’s the sign of a good component - it disappears under you.

Hoping for a mechanical pain killer

I just joined this forum - after buying the Shockstop. I have been diagnosed with shoulder impingement that punishes me during and after I ride. I'm pretty sure arthritis and inflammation is part of the mix too. I really need this product to be successful for me to have a happier retirement.


I got the shock installed at a LBS who didn't know much about them and they gave me the setup that the Shockstop comes with from the factory (135 lb person with dropbars - FWIW, I think they figure you are riding on the hoods where the deflection is greatest). Anyway, I'm about 90 lbs over that and figured that it would not be a good adjustment for me. Took a test ride, thought the stem felt too mushy, so I went home and replaced the elastomers using Redshift's guidance for a person over 205 lbs using the 90+50 elastomers. Determining that this setting was too stiff after a regular ride that included a couple decent hills, I reset the stem for something in between using the 80+60 elastomers. This is the setup I will ride on a metric century this weekend. I will try to post the results of the Shockstop after this ride next week.
