The Sirrus/Vita Master Packaging Fender Set includes five fender sets that fit on our Sirrus and Vita bikes. And with pre-adjustments, the fenders can be assembled fast and easily on either of these bikes. The fender sets are constructed from strong, lightweight aluminum, and they're intended for use with both our Plug + Play and standard eyelet mounting systems. Lastly, they can accommodate up to 32mm tires, and feature stainless steel stays and hardware.
