Aluminum fenders are much more durable and stylish than cheap plastic or quick-release fenders, and cover the bicycle and the rider much better.

The fender set includes all parts for installing the fenders.
Your frame must have braze-ons in dropouts for fender bolts.
The front fender is installed to the fork crown either via the included daruma bolt (to the front brake bolt) or with an L-bracket (not supplied). 
Rear fender is installed with a wrap-around band if your frame does not have a threaded hole in the brake saddle.
