The ultimate in puncture resistance
Because of its unique bumpy design, the MICHELIN Protek Max inner tube creates a compressive force if it is holed or pinched (the hole seals itself naturally) whereas a conventional inner tube stretches (balloon effect).
Ease of fitting
Thanks to its square shape, the MICHELIN Protek Max inner tube positions itself naturally in the rim well and does not twist, unlike a completely tubular conventional tube.
