The Topeak DeFender FX Front Fender is designed for mountain bikes with suspension forks. It comes in two halves. The front half is higher than the back. It attaches to the fork via a quick release that fits under the fork crown. On and off in seconds. Made from injection-molded nylon. The fender is 23" long by 3.5" wide by 6" tall. The weight is 180g.
I strapped both the rear and front fenders of these onto my commuter bike and they work very nicely. Particularly, the front fender is lightweight and incredibly easy to attach and to remove. thus although these were made for mountain biking, they work well and get the job done for commuter bikes too. Definitely worth your time if you want to ride around on a nice and pretty bike despite poor weather conditions.
These worked out GREAT on my Trek bike. They were easy to install, lightweight and makes my bike look more sporty. Now I can ride without the mud all over me. Make sure you look at the price as well..............GREAT price and a good product.
Have it on a 29er. Live on a rainy AK island, and it is definitely a huge help. The only problem i have is that there is not enough space between the front piece and the fork for the break line so it has to run beside the fender and pushes it a bit to one side- which lets a bit more of the sludge launch right into the air where my mouth/face/eyes/nose are all about to be... But does a pretty good job, and once it was really tightened into the fork, it hasnt moved..
