The Protek Max inner tube has a few special features. With a square cross-section, its unique shape makes it easier to mount and fix the inner tube on the rim while eliminating twisting.
The studded design, combined with the prior injection of a sealant liquid, effectively limits puncture risks. It also maintains tyre pressure through thick or thin.
