SKS made the X-Blade for folks who want a super-basic rear fender for occasional use. It clamps around your seatpost and it pivots both at the post and at the interface between the clamp and the fender itself. This dual-pivot design allows you to customize the exact position of the fender over your rear wheel for any size road bike. Ideal for riding in areas where the roads are wet in the morning (we think of misty San Francisco) but it's not actually rainy out. Total weight with hardware is 205g and it comes in Black only. One other note: we recommend pairing the X-Blade with the X-Board to get a similar level of protection from the spray of your front wheel.
