Michelin have unveiled a new bicycle inner tube they have been developing, which when punctured reseals and repairs itself. The Protek Max inner tubes not only contain a sealant to help with the repair process but also compress when punctured to help with the repairing process.
The new Protek Max inner tubes have a slightly different square style cross section and profile to standard tubes. Which Michelin says helps the new inner tube align with the tire casing and against the rim well and provides easier fitting, eliminating the twisting problems, that are sometimes associated with standard inner tubes.
The design of the new Protek Max inner tubes allows them to compress when inflated rather than stretch, due to its unique textured outer surface. This compression helps seal any punctures and helps the internal sealant repair the hole quicker, providing a stronger, longer lasting repair.
The new Protek Max inner tubes are available in sizes of 700 x 35-47c (200 grams) and 26 x 1.4-2.125 inches (260 grams), with Presta or Shrader valves, for a suggested retail price of $8.99.
