Got done with my last fender tweakage. I may go back and swap the single eyelets per stay for double eyelets later on, but for now I'm satisfied with the stiffness with this arrangement using backing plates.
These are really long fenders. I'd have to cut them back in order to add mudflaps:
I was so sick of fender tweakagery that I almost blew off the front fender mount at the Nitto M12 mini rack. It seemed pretty stable without it. But I soldiered on and I'm glad I did:
The spacer is M6 sized, I didn't have anything appropriate for an M5 bolt. Maybe I'll replace it someday, although it works and looks fine as it is. Note the faucet washer vibration dampener. This connection, like all on these fenders, has a homemade backing plate like this:
Overall, I'm pleased with these Civia fenders. Very high quality and a heck of a deal at around $40 USD.
