Ultimate Vybe GR Suspension Seatpost – Active When You Need It

by 9

The Ultimate Vybe GR suspension seatpost has 50mm of tuneable, vertical active travel to absorb bumps and rough terrain.

Things I liked:

  • No horizontal movement
  • Great impact reduction on rough roads
  • Seat clamp isn’t terrible to adjust

Things I would change:

  • I wonder if the spring range could be more defined
  • Post could arrive with all springs instead of having to choose one (you may gain/lose weight, or sell it on)
  • I’m really struggling to make up some things I didn’t like

The ‘medium’ spring

When you order the Vybe GR seatpost there is a dropdown menu for the spring rate based on rider weight, and the only width available* is 27.2mm so it’s an easy choice to get what’s right for you, assuming you fall comfortably into the spring rate options.

*The Vybe suspension seatpost is under the mountain bike section, and is available in 27.2mm, 30.9mm and 31.6mm.

Spring Rate

  • Soft, Rider Weight 38kg – 55kg
  • Medium, Rider Weight 55kg – 80kg
  • Hard, Rider Weight 80kg – 100kg

Those spring rate ranges seem quite broad, so there’s a ‘Pre-Load Adjustment’ screw at the bottom of the post so you can fine tune it. I weigh 70kg, I have the medium spring and have the pre-load screw tightened in about half way, therefore compressing the spring slightly.

The Vybe GR seatpost features the EVO clamp, which is quick-fitting and relatively simple to adjust. It offers a full range of saddle tilt adjustment and the initial saddle fitment isn’t a fiddly nightmare, the bolts are long enough to not have to fully remove the top of the clamp to get your rails in.

You’d expect that when sat down on the saddle churning away, really putting some power down on the pedals, that the seatpost would bounce or absorb some of the power, but if it’s set to your weight it doesn’t. This seatpost acts rigid when you want it to, and only has active suspension when there’s shock to adsorb, assuming you have set it to your weight accurately.

I have mine set up so that potholes, grids and really rough terrain will activate the suspension. It could be setup to be more sensitive, but I don’t ride my gravel bike off-road very much. I have tried it in a more sensitive setup and it works really well on gravel – would certainly reduce saddle soreness for a long day out on bridleways.

Within the USE seatpost range, the equivalent rigid aluminium seatpost is the Alien at £80.00, and it weighs ~120g less than the Vybe (give or take the 10g added to the springs as they size up). So it’s £40 for a comforting shock absorption, which I think is a bargain.


The Ultimate Vybe GR suspension seatpost is one of those components that I didn’t need, but now I have it I can’t imagine riding the bike without it. Commuting to work via Pothole Alley, riding Calderdale cobbles, dodging traffic by taking the canal towpath are all made smoother and more comfortable with a bit of active suspension under me.

    I’ve had the non-GR version on my gravel bike for a couple of years, and found the 30mm of travel to be just about enough* to stop me getting kicked up the arse off-road, meaning I can run my tyres that little bit firmer and keep my me-shaped Brooks saddle in service. 20mm extra travel sounds like it’d make for a much more comfy ride, with much less chance of the occasional bottom-out (so to speak).

    Oh, and when messing about with pre-load, don’t do what I did and accidentally unscrew the spring retaining allen bolt – it takes forever to get it back in on a medium spring.

    *or not quite enough, depending on the terrain.

    @belgianbob I thought I’d broken it forever when I took the cap off. I had to have a coffee break between efforts to get it screwed back on!

    I’ve been running a XCR USE post on various bikes for the last 2 decades. Currently a SUMO head version on my mk1 solaris.

    they are good for what you want them to do. there’s lots of talk of the saddle height dip when it sags etc, but it just depends on how you set it up. Like in the review, it can be set to sag a mm, and take out most but not all of the chatter, or sag a little more and really smooth things out.

    The point is IME, and I’m very saddle height sensitive, you dont notivce the drop in saddle height when riding bumps, as the bike comes up to meet you anyway.

    I recall USE had a good run ‘hiring to buy’ at the mountain mayhem at sandwell many years ago after fatigued bodies realised the benefits of a suss post riding the ploughed field of doom.

    I remember having one of these in the early nineties, coupled with a Girvin Flexstem, and thinking I was so cool because I had full suspension.
    Great shout for a gravel bike

    Ultimate Vybe is not an appropriate name for a saddle related implement… unless sold by WISH

    I used to dismiss this style of post in favour of the linkage style thudbusters, but given how quickly the Thudbusters seem to develop rattle and play I’d be considering one of these in future I think.

    Wow, I used to have one of these, in 1992 when they came out, on my Salsa hardtail. AFAIK it’s been in USE’s range ever since. Great for tandem stokers too.

    I have one of these on a hardtail and I love it. It is great when you need to keep speed up seated on bumpy ground and keeps bad backs at bay.
    Really helps on turbo sessions as it keeps movement in the saddle when seated for a long time.
    It has transformed my riding enjoyment

    I’ve a suntour ncx which is a parallelogram post like the thudbusters. I think it works a bit better than the old use post I had, and it was dead cheap
