These fenders fit my Sinch perfectly and look great. There is no vibration or rattle. Love the mat black finish!
The only reason I took off a star is that I think they sent the wrong size for my frame and I had to drill a hole for the screw to attach at the crank for the rest fender. Also, there were no instructions. But these were included free with my bike and as such I'm very pleased. If I were shopping for fenders on their own, I would basically choose based on price. If these are a good price, and you're in the market, they're perfectly good. No rattling, fit well.
The fenders came with no directions, also package was short of the required bolts and washers. Nice fenders but poor quality control.
Fenders arrived with bike, they are a good quality fender. Only problem no instructions on how to install. Used common sense and installed with few problems on which screws to use at each location.
1. Instructions sorely lacking. No diagrams and no video instructions to install.
2. I had to take to rear tire off the install.
3. I had to bend the fender struts for the to fit properly. If I did not bend them them prevented the brakes from engaging. I emailed them over a week ago and still have not received a response.
