I have used one of these for 2 years for use in the winter, it's simple and effective. I must admit, I really didn't think it was going to work to start with, mud does cling to the back of it, but i was really surprised how effective it was. I have used a marzocchi intergrated fender and a THE dh fender, but they are just 2 bulky and a like to see the front wheel! Never been a fan of crud catchers either, always seemed a bit pointless. Mud is part of the fun, the Neoguard, just stop enough so I can continue to see where I am going, without having to wear goggles!!!
