🚴 Premium Michelin A3 Airstop 35/47 x 622/635 Tire Tube for City Bikes - Front or Rear | 40mm Valve Review

Excellent quality. Easy to assemble, everything fits. This may not be a review of a product reviewed here, but I've come to appreciate Presta 9 valves after owning Schrader valve-only mountain bikes). They are a little strange at first, but they are easier to inflate by hand.

Air tubes have been used for many years. I can set my tires to max pressure and not need to add air for about 2 weeks, after which I notice a loss of about 5psi. Great tubes well worth the price considering local stores charge around $7-9 for cheap generic tubes.

Stop buying Kendas and other East Asian tire brands. This tire is a business. I've been using Kendas on my city bike for years and find myself replacing the inner tubes every year. I would also have to air the tires every other day. This tire only dropped 20psi from the 80 I normally ride after a few weeks of use while the Kendas dropped to 20-30. I will definitely buy more.
