Michelin A3 Protek Max Presta Gravel Inner Tube 700x33-46

To set off on adventures on your gravel bike with complete peace of mind, you need a sturdy inner tube to avoid a puncture on the first technical section. With this Michelin A3 Protek Max Presta, you’ll have nothing to worry about. Featuring a special dimpled design, this inner tube is made from butyl to ensure excellent air pressure retention.

What’s more, it offers excellent puncture resistance thanks to an internal puncture-preventive liquid. Acting under compression, rather than under tension as with a conventional inner tube, this Michelin A3 Protek Max is therefore as effective as possible. Suffice to say that all riders with a gravel bike fitted with 700c wheels and tyres with a width of 33 to 46 will be impressed.
