Zefal Shield Lite M Under Saddle Guard
8 10

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.

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

Rate the product for durability:
 
8/10

So far it's resisting the constant bending/unbending from under the saddle and doesn't seem to be weakening anywhere. At this price it is a disposable item.

Stu knocked out his first road.cc review back in 2009 and since then he's chucked the best part of seventy test bikes around the West Country, a couple of them quite literally! With three alloy and two steel bikes in his fleet he's definitely a metal man (that'll be the engineering background) but is slowly warming to that modern carbon fibre stuff along with fat tyres & disc brakes.
It's not all nostalgia though, after spending the last few years in product design Stu keeps banging on about how 3D printing is going to be the next big thing and he's a sucker for a beautiful paint job too.

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.

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

Less is more.

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.

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.
