Focus’ entry into the comfort seatpost market is undeniably strange-looking, but we rather like it.
It’s like a standard carbon post, but below its head is a large cutout. This means the saddle is effectively only connected to the bike by two narrow sections of material, allowing for a good deal more flex than a conventional post.
A 350mm long, 27.2mm diameter post weighs in at a respectable 199g.
There’s nothing complicated about the CPX Plus, and its two-bolt clamp arrangement is conventional and straightforward. Saddle angle adjustment is a case of alternately tightening and loosening the bolts, and there’s no compatibility issue with different types of rails.
With care, you can actually swap saddles without removing the bolts, which saves time and faff.
Like most posts, the Focus is not going to turn a boneshaker into an endurance machine. It does, however, absorb the high-frequency vibration of broken road surfaces very well.
Seatposts come a long way down the list of priorities in getting a bike to feel right. But if you’re looking for a marginal gain in comfort, or simply a good-quality lightweight post, the Focus is a solid choice.
