Grey by day - bright by night!
The reflective colourway comes alive under torchlight, enhancing your viability to others in the dark. It also looks cool AF!
Perfect for anyone who cycles on the road, particularly in the winter months!
Grey by day...
The reflective ink is a cool, subtle grey in the daylight.
Bright by night!
The fender shines bright in the dark when shone over by torchlight. This greatly enhances your visibility to others when cycling on the road.

This was too easy. It does a great job covering the normal "splash" zone and I really like the height, so there is no chance it can interfere with the tire.

For not having any zip ties or tape to hold it in place, it's really sturdy. It doesn't even move when I'm driving down the highway at 75 mph for 15 miles with the bike on the bike rack. Love it!

It is a bit fiddly to get it in place, but once in it stays stable in place. The wide area provides sufficient coverage to protect the butt from the distinguishing brown marking fenderless cyclist have on rainy days.There is still enough space to mount a saddle bag underneath the fender, but you have to remove the saddle connector. This makes this fender a more permanently mounted solution and not something you stick on quickly before you head out.

Great for the price. Temp use only. Could be more sturdy.

I had the old version of this and it worked pretty well. The only complaint I had was that it was a little floppy and with the seat dropped it would hit the tire on hard landings, but it never folded under the tire. The new version supposedly added some rigidity and a little flap to help keep it from hitting the tire or getting stuck on it. They also stated they added a tab to make it easier to install. Neither worked. It was way harder to install than the old one. The first mild bump I hit with the seat dropped it got stuck and folded under the tire. Had to stop and pull it out and then it did the same thing next bump. It's completely unusable. Very disappointed and sending it back.

I had 2 others I purchased a few years ago the lasted well. This one broke as soon as I installed it.

Did NOT fit under my bike seat in the least bit. Unable to use it at all...

So far so good. It's discrete and looks good.Update:Does not do well on bikes that have a large distance between the seat and the wheel... May as well not have a fender.

Pas aussi abouti que les autres garde boue de la marque. A tendance à tourner.

Leggerissimo e robusto. Solo un pochino macchinoso da mettere su selle racing.
