Maxxis Colossus Tube - 27.5" x 4.5"

Premium inner tube sized at 27.5" x 4.5" for the Maxxis Colossus and similar fat tires found on Surface 604 Boar Explorer models. The slightly larger diameter pairs perfectly with the 27.5-inch fat rims used on Explorer frames.

Schrader valve for easy inflation with standard pumps. Carry a spare on every ride — fat bike tubes in this size are a specialty item that most bike shops do not stock. One tube per package.
