Ergon Allroad Pro Seatpost Review: The Holy Grail For Gravel?

The Ergon Allroad Pro carbon seatpost has a very unique twin-leaf construction, which allows for a lot of vertical deflection. And you can really feel it, even while pedaling on smooth sections of the road.

The advantages of using this kind of suspension on a gravel bike are significant in terms of comfort. Let’s take a closer look.

Ergon Allroad Pro Ride Feel

The first thing you notice while riding on Ergon Allroad Pro Carbon (also known as Canyon VCLS 2.0) is the now muted feeling of the road below you. It’s almost as if you’ve got a slow leak in your tire.

But after a bit more distance on more challenging ground, you will also notice that you don’t have to lift your butt to avoid bigger hits. You can basically stay seated all the time, focusing on your pedaling and maxing out your ride enjoyment.

This is a ground-breaking change that will allow you to ride faster and more comfortably for longer periods of time.

For some, the feeling of seatpost bob is a disadvantage, but I never found this a problem (I got used to it straight away).

Of course, the more exposed seatpost length you have, the more flex you receive from the seatpost. If there is little seatpost sticking out, you might not even notice a difference. And keep in mind the 25 mm setback seatpost variant will offer you more flex than the zero setback post too.

But the big question is exactly how comfortable is the leaf-sprung Ergon seatpost?

Ergon Allroad Pro Comfort Testing

To find out just how many vibrations were attenuated by the Ergon Allroad Pro seatpost, I tested it alongside my FSA K-Force carbon seatpost on my Jamis Renegade benchmark bike (Panaracer GravelKing SK 43mm tires). The FSA K-Force seatpost is well-known for mitigating vibration – even in the zero setback version that I have.

However, riding on my FSA K-Force on gravel roads and trails is noticeably worse than the Ergon Allroad Pro. You can no longer stay seated while pedalling through bumps, and you can definitely feel the bigger hits on your butt.

Vibration Test Results

You can see my vibration measurement procedure & outdoor test courses HERE.

The bumpy forest trail measurements I took showed that with my tires at 40 psi, the Ergon post was absorbing 7.9% more vibrations, and it was a touch more comfortable again with 20 psi.

This is less than I would have expected, but then again, the FSA K-Force is not just any old seatpost – it’s one of the best carbon seatposts you can buy in terms of comfort. I suspect the differences would be MUCH larger if we were comparing a straight aluminium seatpost.

And on the fast gravel road, the differences were a touch smaller but still noticeable – the Allroad Pro was 2.9% better at 40 psi and 6.4% at 20 psi.


So, can I recommend the Ergon Allroad Pro seatpost?

Yes, definitely! It’s likely the most comfortable carbon seatpost available for both fast gravel roads and bumpy forest trails. I really like that you don’t have to lift your butt to avoid bigger hits, you can simply pedal through them.

I will be keeping the Ergon Allroad Pro on my benchmark bike for the next while.
