There are two types of fenders: Plastic and Steel.
Our suggestions are:
- For plastic, the spool will push down the fender to the tire for a snug fit.
- For steel, you could take foam pads, and cut it to wrap around the spool so that the fender will not get scratched.
We will be releasing a pad that is matched to the spools and are determining the best material for the job.
NOTE: Sorry, but we are not responsible for any damage to fenders due to these suggestions and your usage of them.
