ShockStop Suspension Stem

Long road rides and gravel endeavors take a toll on your body as is, and jarring forces add on to that fatigue while you ride. Redshift Sports aims to take on the harsh vibrations by adding up to 20-millimeters of suspension to the front end of your drop-bar bike with the ShockStop Suspension Stem. The stem uses 5 swappable elastomers that you can fine-tune to the perfect feel for your ride (ships with two pre-installed, three extra), and flexes just right when you encounter rough terrain, potholes, and brake bumps. It's crafted from 6065 T6 aluminum that offers long-lasting durability, and opts for a minimalist design to keep aesthetics looking tidy on your traditional road or gravel bike. The stem is available in an array of lengths with a 6-degree rise, or a 100mm length with 30-degree rise for a upright fit.

A great addition to my gravel bike

Familiarity:
I've put it through the wringer
Size Bought:

This did exactly what I was looking for ? reduce uncomfortable, fatiguing shocks through the handlebars while keeping the sure-footed compliance. A month ago I purchased a new bike and knew I wanted to take it on and off road. I did not want a fully suspended bike, but rather something to absorb those shocks from potholes, rocks, sharp transitions. On my motorcycle I had found bars with elastomer absorbers, so I set out hoping the same existed for my gravel bike. When I came across this stem from redshift, it seemed to tick the boxes. I bought it to test and have never looked back. Riding around LA our streets arent always in the best shape. This has been amazing. Not soft but a firm shock absorber. I've got about 400 miles on it so far and have recommeded to many others. It is worth experimenting with the various elastomer inserts. I ended up going with a little softer than recommended and it works for me. I used the same geometry as my original stem to maintain riding position ? a colleague opted for the higher version as he was looking for a more upright riding posture. I have since also purchased their shockstoper seat post. together they have made my riding more comfortable, less painful and therefore allowing me to go a little further and on more challenging surfaces.

Redshift Stem Shock

Familiarity:
I've put it through the wringer
Size Bought:
110M - 6 degrees
Height:
6' 2"
Weight:
210

I have put about 500-600 miles on this shock over the last month. Riding both road and single track and I really dont feel it when I ride which i like as I dont feel like it impacts my energy transfer very much at all. I am sure it does but minimally as I have installed the stiffer polymers (not the factory default). On long rides (50+ miles) my shoulders dont get sore which they still do on my other road bike also I can defintley ride faster over rough patches. I am setting PR's all the time while feeling better after my rides. It was dead easy to install. Stats: I ride a roughly 3-4K miles a year, 6"2' tall 210 and I am almost 60 so not out to kill it but i do ride hard. This is mounted on my Trek Checkpoint 6. I like it a lot!

My husband bought this for me and what a life changer it is!! We put this on my Sirrus X 3.0 Gravel Bike. It really takes the edge off. I find that I can ride longer with comfort and less fatigue.

like most people i was suspicious of how useful this would be. after my first ride im totally sold. this changes the game when it comes to gravel riding. highly recommend to anyone looking to smooth out the rough stuff.

it really works

It took me two years to finally pull the trigger on buying this and I wish I?d done it sooner. I have two buddies who?ve had it since it first came out and both swear by it so I should taken their advice immediately. It makes a huge difference even though you don?t really notice the stem moving except on the biggest hits. It makes my arms, shoulders, neck and lower back feel a lot fresher than normal after a long gravel ride. It softens the chatter and pounding making it feel like I?m running larger-volume tires at a lower PSI. I had to flip my stem which required some moving around of the elastomers but it was easy even for a mechanically challenged fool like myself. Go ahead and buy this. It?s well worth the money.

As good as advertised

I read/watched a lot of reviews before purchasing but I was still skeptical. However the redshift stem works just like it?s supposed to, it softens the ride without feeling like you have a bouncy stem. Most of the time you don?t notice it at all, but on rough gravel roads you will notice a slight flex. What you?ll really notice however is how much better your hands and shoulders feel after long rides on tough roads.

I got this stem for a carbon fiber hybrid bike. The rough roads had really been playing havoc with my hands. I installed the stem and took it out for a ride, it amazingly improved ride. I put in the 60 and 50 shims and really felt very little wiggle or give. The road damage no longer was unpleasant and it rode very well at all speeds and conditions

Not a gimmick - works great

Familiarity:

This stem is a tad heavier than the carbon stem I replaced on my S-Works CRUX. Have to say it is one of the best additions to a bike I?ve ever installed. I installed elastomers that matched my height, weight and style. That was extreme say. I felt no loss of responsiveness. What the stem does exceptionally well is crush chatter on cobble and other terrain. Reduced wrist fatigue. Gave dampening on sharp obstacles. Cant imagine going to an alternate stem.
