Genetic STV 143 saddle



Nice overall shape but could do with softer padding especially at the nose

At every product is thoroughly tested for as long as it takes to get a proper insight into how well it works. Our reviewers are experienced cyclists that we trust to be objective. While we strive to ensure that opinions expressed are backed up by facts, reviews are by their nature an informed opinion, not a definitive verdict. We don't intentionally try to break anything (except locks) but we do try to look for weak points in any design. The overall score is not just an average of the other scores: it reflects both a product's function and value – with value determined by how a product compares with items of similar spec, quality, and price.

The Genetic STV saddle goes a long way to provide comfort for long rides with plenty of flex and a cut out in the middle but it's all undone by overly firm padding and a solid nose. A seat for those who like a firm perch.

The STV is available in three widths with this test model here being the middle option at 143mm wide at the largest part. You can also get a 130mm or 155mm wide version to suit your preference and sit bones. Length is 278mm and the rails have 50mm of adjustment between the front and rear maximum markers.

I really got on well with the shape as the rear narrows into the nose quite quickly giving loads of room for my thighs.

It's billed as a sportive saddle and to that end STV has been designed to offer comfort by reducing pressure on the perineum by way of a central channel and a cut out of the nylon reinforced base.

The cut out only removes material from the base rather than the upper too but it does bring a certain amount of flex to the hull.

The hollow chromoly rails also flex a bit as well so on first inspection you'd think the saddle is going to be pretty comfortable. Unfortunately though the padding is on the firm side and the flat nose section doesn't budge at all which makes for a very solid feeling saddle that – for me at least – is uncomfortable unless you are just out for a short blast.

On any ride approaching three or so hours I actually found myself in quite a bit of pain which is a shame as in general I actually got on with the overall design. I appreciate saddle shape is a personal thing but I'd be surprised if anyone actually found the STV plush.

The overall finish is okay for the money with the PVC cover being stretched over the top and stapled to the bottom of the hull rather being sandwiched by twin hulls as you find on more expensive offerings.

When it comes to weight it's a similar story, against others that are similarly priced the STV is right in the ballpark.

Personally if I was looking for a saddle for longer rides like a sportive I'd be looking at the Fabric Line; the chromoly-railed option comes in two widths for the same price as the STV.

The Genetic STV 143 offers pretty much what you'd expect for the money but I just found it too firm especially from a sportive saddle that you'll be spending a lot of time on.

As part of the tech team here at F-At Digital, senior product reviewer Stu spends the majority of his time writing in-depth reviews for, and ebiketips using the knowledge gained from testing over 1,500 pieces of kit (plus 100's of bikes) since starting out as a freelancer back in 2009. After first throwing his leg over a race bike back in 2000, Stu's ridden more than 170,000 miles on road, time-trial, track, and gravel bikes, and while he's put his racing days behind him, he still likes to smash the pedals rather than take things easy. With a background in design and engineering, he has an obsession with how things are developed and manufactured, has a borderline fetish for handbuilt metal frames and finds a rim braked road bike very aesthetically pleasing!
