The Canyon VCLS Post 2.0 is a suspension seat post – there, I said it. That term has been the elephant in the room, something that we all knew, but didn’t want to talk about. Say suspension seatpost to a roadie and it brings to mind great hulking contraptions that wouldn’t look out of place in a Heath Robinson catalogue. It’s something that a true, dyed in the (merino) wool, road riding cyclist would ever admit to needing.

 

Suspension? Pshaw! That’s something for tourists and mountain bikers! But remove those blinkers for a moment and it starts to make sense. While riding, we are subject to a constant assault from the road surfaces we ride on; cracks, potholes, lumps, gravel, white lines, manhole covers; the list goes on. When riding over these, the shock is being transmitted through the wheels and frame to your hands, feet and rear end.

 

Modern bike design and frame materials can alleviate some of this, but it still seeps through and this is where your body’s natural suspension comes in. Arms, legs and core muscles all work to absorb the vibrations and this takes energy; energy that you really need for riding. So anything that can assist your body to save this energy will mean more power for you to use for pedalling.

The VCLS Post 2.0 needs at least 155mm unclamped to allow it to flex

 

Canyon realised this and set about designing a very elegant solution to the problem. The Canyon VCLS Post 2.0 is made from two D-shaped carbon sections that are clamped together on their flat edges. These taper in thickness and flare out towards the seat clamp. This tapering means the top end can flex and the D section limits that flex to one plane. Simple. All the flex in the VCLS Post 2.0 happens in the top 155mm, so you need to be certain you have enough room to allow for this. One of my frames was just on the limit, a frame slightly smaller than I normally ride, so beware. However, it also happened to be just about the most uncomfortable, old school aluminium frame I have, so would be perfect for testing the Canyon VCLS Post 2.0.

The Flip Head seat clamp allows the saddle to move a little, which helps keep it level. Two bolts on the side of the clamp hold the saddle in place and in this position are very easy to adjust; well done Canyon. No more fiddling around with bolts that you can’t see and dropping your allen key on to your seatstays! The Flip Head can also be rotated 180º to allow extra fore and aft adjustment.
