The PRO FMB Super Mud tire. With black rubber tread and the PRO cotton casing.
This is a hand built 700 x 33mm tubular cyclocross tire.
The cotton sidewalls are coated with a thin layer of latex that covers the edge of the tread and overlaps onto the base tape to create a highly water resistant protective seal.
FMB tires DO NOT require "Aquaseal" or any other post production treatment to be highly water resistant and durable.
