Review on Portland Design Works Shovel Fender by Nigel Cohen

Good material quality. Assembly is easy. The clip on the mechanism is quite tricky as you have to pull on the elastic that holds the clip firmly in place to attach it to the round seat post. I find that a layer of tape on the bar helps the rubber band grip the bar better. I will try and update. At this point it is not tight enough to prevent spinning on a smooth cylinder, which is a common technical problem with cylinders. It's really close to perfection and can be modified to keep it from spinning. The company is solid with great customer service. Considering the price, small fixable mounting issue and functionality, I recommend fat tire bikes.
