Jamis Quest Audax - SKS chromoplastic mudguards 4

The venerable SKS Chromoplastic mudguard has been a staple for audaxers, tourers and commuters for decades, and the latest incarnation is everything you'd want: sturdy, well made and decent value.

The Chromoplastics are made by sandwiching Aluminium stips inside a plastic housing. The resulting profile is quite deep which makes it stiff and sturdy, and it carries the now-trademark pattern of black strips and see-through channels. Fixing kit is all steel, with a fixed bridge at the rear and a sliding one at the front for better adjustability.

Beefy 3.4mm stays fix them in place; there's SKS's Secu-Clip at the front too which holds the stays securely but is designed to pop out in an emergency such as a stone caught under the guard. You can fit them to the rear too if you're running a fixed or hub gear, as it makes it a good deal easier to get the wheel out. There's a mud flap on the front guard and a reflector on the rear.

Fitting the guards is fairly straightforward but they're not the easiest; I found the plastic covers for the stay ends a bit bothersome and they're no better functionally than a simple rubber end cap. A decent set of bolt cutters makes chopping the stays to size a simple job. Once they're on, they're on; these aren't the kind of mudguards you throw on on a whim. You need half an hour to do a decent job of it and get everything nice and tight.

The P35 version that I tested is rated for a 20-28mm tyre (they're available for up to 60mm tyres) but a 28mm would be a real squeeze as the 25mm Zaffiros on my bike were pretty snug. Pretty snug meant barely any spray though; the profile of the Chromoplastics does a super job of keeping you dry and they're a sensible length too.

If the road surface is really wet you'll still get water splashed at your feet but you won't get spray from the tyre, and your riding buddies sat on your tail will be happy bunnies too. If you want to be really nice to them, fit a long flap at the rear. The front was a bit rattly at first but a bit of judicious plierage locked the brake bridge in place and kept them quiet, and they've been perfectly behaved ever since.

All mudguards rub from time to time but these SKS units are better than most thanks to the sturdy construction. The tight fit around the tyre meant the odd bit of sidewall rub on the climbs, but that's more down to flex in the wheel than any issue with the mudguard itself.

Normally the benchmark of a particular product is one of the most expensive available, but you can spend a lot more than the £34 you'll pay for these and get guards nowhere near as good.

My heart sank everytime a customer wanted SKS mudguards fitted, the bloody things always had a curve to them that no amount of adjusting could correct.

That and you needed a flak jacket and helmet when trying to cut the stays.

They were pretty sturdy though!

I've only ever used SKS and ESGE (which are one and the same). Whilst a bugger to fit at times, they're well worth the effort and pay dividends in terms of longevity.

Don't even consider anything else. These really *are* the best. Wink

I have similar Tortec chromotec 26" units on my old rigid MTB and find them very effective in all weathers.

Those plastic end caps - snap off the part that you're supposed to fit around the stay bolt, so that you're left with the domed cyclinder, and you can use them like the old rubber end caps, ime. Far less faff.

My only complaint is that the larger sizes have a rigid plastic mudflap up front that's not as good as the flexible one on my P35s. Keep meaning to change it for a bit of damp proof membrane, or something.

"a fixed bridge at the rear and a sliding one at the front for better adjustability."

Shouldn't that be the other way round? i.e. sliding at rear, fixed at front?

I agree the other comment - they are never totally true and have a twist you can never totally get rid of.

One moan, why do they still use aluminium rivets. After a few seasons in the winter, the salt corrodes them and they fall out. Most of mine now have st. stl nuts and bolts or ty-wraps holding the stay bridges in place.

I've got these on my Boardman CX, running Marathon plus in a 28 with no clearance problems at all. Rear guard went on no problem without any cutting needed but front needed a bit of fettling not least to miss the disc brake calliper. Got to say I was quite pleased with the result. Agree with cutting off the plastic sheaths - I just super-glued them on. This is the second set I've fitted and never managed to do it in less than two hours, but then I do faff around quite a lot.

Replaced the front bridge with a new rear bridge so I can have the front guard sit lower to the ground. Party
