SKS VELOFLEXX 65
If your bike has no suspension forks ( maybe a gravel bike with big tires )and you want to use this, simply exchange the rear and front mount ( velo strap ). I was able to put this on my gravel bike with 27.5" 2.4" wheels.
Fittes on an on-one inbred with maxxis hookworm tires. Clerance are really narrow but just enough. The fender has big coberage so works really well.
