These SKS fenders work well on the 20-inch wheels. They fit tires up to 1.75 inches wide. When we pack and ship the bike to you there will still be bolts to install your fenders when the initial fit and installation has been done at Bike Friday. If you do the initial fit and installation there will be more steps.
Please note if you have a Haul-a-Day, the fender stays need to be bent into a special configuration before shipping. Please indicate in the checkout notes if you want the fenders prepped for a HaD installation. Thanks.
