I installed the Planet Bike Cascadias earlier this winter because the road slush and road salt spray was so extreme I couldn't keep my chain and bottom bracket area clean. They are especially good to keep your feet dry and the spray from the front wheel off of them. I don't know how I rode without them before now. I thought they would make my bike look somewhat "freddie" but no, they just installed so cleanly and close to the tire that is actually made my bike look classy and luxurious. I love them.
