Zefal Shield Lite M Under Saddle Guard



Secure fitting spray guard – in any colour you want as long as it's black

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.

What the scores mean

Good scores are more common than bad, because fortunately good products are more common than bad.

For some, mudguards aren't cool – but neither is that mud stripe up your bibs and back. So what should you do? Chuck a few quid over the counter for Zefal's discreet clip-on Shield Lite M Under Saddle Guard, that's what, and enjoy a dry derrière.

There have been a few of these on the market for a while now, and you'll even see the pros using them on the TV, but as far as I'm aware the Zefal is the best fitting.

Being stamped out of a sheet of polypropylene, the Shield is simplicity itself, shaped to bend into and out of position in a matter of seconds.

As long as you have a standard-railed saddle (a rail either side), the Zefal will fit no problem. I've tried it on round tubed and even square section carbon with no issue. The rear two round cutouts slot neatly into position.

What differentiates the Shield from others like the Ass Saver or Velox is that the front section, which bends down to meet the rails, has more cutouts for location. This means it is more stable in use; maybe not by much, but enough to make a noticeable difference.

On a wet day you simply unfold it to provide coverage, and while it's not going to offer the rain-saving ability of a full mudguard, it does a good job of keeping the worst of the muck and soggy chamois syndrome at bay.

So far it's been swapped between various bikes and the bend lines aren't showing any signs of weakening after being constantly folded and unfolded, so it should last a while too.

The price matches that of the Ass Saver and Velox, but obviously you can shop around for better deals. I personally think the Zefal is worth paying the full whack for anyway, so any discount is a bonus.

The only downside I can see is that it is only available in black. Otherwise, it's a great little rain shield that works really well for keeping your shorts dry and clean.

Stamped out of a sheet, there isn't much to go wrong. The notches and bends are in the right place for easy fitting to every saddle I tried.

It's very good at what it does, keeping that mucky brown spray stripe away from your shorts and jersey.

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!

Here is a template to make your own:


The material used is 0.8 mm Polypropylene and the easiest way to source it is to find one of those plastic A4 binders.

Get a much better protector from the 99p/ £1 shop, well engineered and easy to fit to the rear seat

You can pick up something similar to this on AliExpress for 68p. More colour choice, not a dodgy copy (sellers own brand) and cheap as chips.

So its stops the wet stripe up your back, but the back of your legs, your feet? Soaked.

Less is more.

Does it protect my undercarriage when using a saddle with a cutout like the Romin?  There's nothing quite like getting a bidet every time I'm caught out in a storm on the road bike ಠ_ಠ

Yeah it should do as the guard covers the base of the saddle from back to front.
