Failure to install our fenders properly and safely can result in serious 

injury or death.

35mm Mud Butler Fenders: 700 x 18 - 25c (and some smooth, low-profile 

28c tires)

Please follow these directions

, but note that for 

installation  on some bikes, occasionally you may need to get crafty. 

At the end of this booklet you will find a Troubleshooting / Tips and 

Tricks section. We don’t pretend that all scenarios are covered here. 

If something comes up, we would love to help.

We also invite you to follow along with our installation 
video. Find it at: http://bit.ly/installfender
