At road.cc 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.What the road.cc scores mean
Good scores are more common than bad, because fortunately good products are more common than bad.
The Syncros Coast Fender direct saddle mount is designed to work with its latest version of saddles. It offers decent coverage for its design, although obviously if you haven't got the specific saddle, it won't fit.
We've seen many mudguards that fit under the saddle for race bikes, and the new Coast Fender is an evolution of those like the Ass Saver or Mucky Nutz Road Butt Fender, for instance.
What makes the Coast different is that it doesn't just clip over the saddle rails, it comes ready drilled and with a couple of bolts that screw straight into the threaded holes in the bottom of saddles such as the Syncros Tofino 1.0, which is also in for testing.
This obviously limits its appeal, but for those with the right saddle it does a pretty good job if you want a bit of protection on a bike that doesn't allow full guards.
The usable part of the guard that pokes out from the saddle is 160mm in length and 80mm in width and it stops a surprising amount of water and mud.
I've been using it on a cyclo-cross bike and it is ideal for those situations like when racing but you don't want to end up with a soggy chamois. I found that it kept the spray off the saddle and the back of my bibs and some of my jacket. It's never going to stop you needing to wash your kit but it does stop some of the discomfort.
It's made from high impact resistant composite according to Syncros, which in real life means it's firm enough not to flex and bounce around but if you hit it with your leg when jumping on or off the bike it's flexible enough that it won't break.
At £8.99 it's not exactly going to break the bank but it is a little bit pricier than the aforementioned Ass Saver, which you can get for about six quid. The Mucky Nutz is also £6.49, but saying that the design and shape of the Coast Fender seems to work, plus there is no chance of it falling off.
You'll need a Syncros saddle but the Fender does a good job of keeping your vitals dry

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 road.cc, off-road.cc 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!
