Ultimate Sports Engineering (U.S.E) have been making bicycle components for many years, I had one of their suspension seatposts on my mountain bike back in the 1990s. Together with the other arm of the business, Exposure lights, they have a well earned great reputation for well thought out and reliable components with excellent after sales service too.
I tested the modern equivalent of that original seatpost and you can read it here U.S.E now have a suspension stem in their line up and I was lucky enough to be sent one for a few weeks to try out.
The stem is available in two lengths currently, 70 and 90mm and unlike other similar stems on the market is rated for use on drop or flat bars. It is constructed of aluminium, weighs 194g for the 70mm version I tested It consists of one main pivot point that squeezes a changeable elastomer that allows the stem to move up to 20mm. The stem also has adjustment for rebound and compression, something I’ve not seen on any other suspension stem I’ve tried so far.


The first thing to say is that it looks like an ordinary stem, which to my mind makes it a much better prospect than some of the huge parallelogram style suspension stems on the market which are quite ugly in my opinion. When riding and you look down it looks good and is not something you’d want to hide!
As with most suspension stems, you need to dial in the stem to suit your weight and riding preferences. U.S.E. include 4 interchangeable elastomers that allow you to do this. The stem does have to be taken apart to swap the elastomers though. Happily there is a comprehensive guide included in the box and it’s on actual paper! no downloads needed. It’s pretty straightforward to swap, just make sure you put the stem back together as the U.S.E. guide states. U.S.E. also include a little tub of grease in the box which is a great touch.
Set up with a yellow elastomer as per the rider weight guide and all bolts tightened to the correct torque I went for a series of rides to test out the stem, I’ve included a video below that shows the stem in action, please take a look (and subscribe to my youtube channel if possible, it’s free!)


So, does the U.S.E. Vybe suspension stem work, well yes and no. Firstly and this is the same as with any “suspension” stem, do not think of it as suspension like a suspension fork, it dampens the vibrations coming off the trail through your front wheel and rigid fork, it doesn’t suspend the rider from big hits. What it does by dampening those vibrations is reduce fatigue on you hands, arms, shoulders and upper body allowing you to ride further and recover more quickly. The U.S.E. Vybe stem does this brilliantly but there is one drawback and this is affected by your riding style.
Because the pivot point on the stem is very near the steerer of the fork the nearer your hands are to that pivot the less the stem moves. What this means when riding on drop bars is that the maximum compliance of the stem is achieved when riding on the hoods. Riding with hands on the drops and therefore further back than on the hoods mens the stem moves significantly less. So if like me you spend a lot of time on the drops for technical descending then you won’t really benefit from having that 20mm of travel. If you ride on the hoods you’ll get much more cushioning as you move along. So pedalling long sections of rough trail like forest fireroads or towpaths that are ridden on the hoods is where the stem really shines. I know for a lot of riders this is exactly what gravel riding is. Others like myself who don’t have that kind riding on our doorsteps and ride XC trails will find less benefit.
Since posting this review I’ve had messages from readers who have seen reviews of the stem where the main pivot bolt came loose during a ride. I can say for the 4+ weeks the stem was on my bike over various rides that bolt remained tight.
The Ultimate Sports Engineering Vybe Suspension stem is a well made and thoughfully designed component with added features over other similar stems on the market. If you are a fireroad/towpath/rough bridleway and typical UK pot holed road rider then it’s an excellent way to reduce fatigue and lengthen time in the saddle. if you push the boundaries of what a gravel bike is supposed to do it maybe of less benefit but who doesn’t ride all the above to get to the juicy challenging routes? Might as well take advantage of that suspension for those section as it won’t hinder you on the downs!
