The X-Tra Dry remains the template that competitors still copy: a simple seatpost-mounted mudguard that installs in seconds, protects your back from rooster tails, and disappears into a bag when the weather clears. The cam-style powerstrap mount wraps around any seatpost up to 35mm diameter without tools, and a single pivot point lets you dial in the angle to match your frame geometry.

The construction uses high-performance impact-resistant plastic that SKS manufactures in Germany. At 380mm long and 80mm wide at its broadest point, the X-Tra Dry covers enough real estate to keep spray off your back and saddle without the visual bulk of full-coverage fenders. The material stays stiff enough to hold its position over rough terrain but flexes rather than cracks if you knock it against something during storage or transport.

The fender sits high enough to clear suspension travel on full-suspension bikes, and the angle adjustment accommodates the varying seat tube angles you'll find across hardtails and trail bikes. For riders who want mud protection without committing to a permanently mounted setup, this is the original solution that created the category.... Read More
