Review: Continental quality and value. - Have used Continental tires and tubes for a few years now switching away from Michelin. Our rides are mostly city urban streets and bike paths and regularly got flats when running Michelin tires and tubes. After switching to Continental tires (Gran Prix 4 Season) and tubes. 🤞🏻🤞🏻🤞🏻no flats. These medium weight tubes and their “supersonic” lightweight tubes perform perfectly. Note these use are in the 70 gram weight range while the supersonic tubes are 50ish grams. Just a bit heavier than those finicky TPU tubes which failed within a month if not right out of the box. These tubes hold air for days if not a week or two. Nice ride and durable. Make sure to order the correct stem length to fit your wheel rims. Toss the valve stem nut never thought they would rattle until I found out it was the reason my front wheel rattled while rolling slow enough to hear it. Go figure
