Continental MTB 27.5" 1.75–2.5" – versatile inner tube for mountain bikes

The Continental MTB 27.5" 1.75–2.5" is a butyl inner tube for 650B or 27.5-inch mountain bike tires with a width of approximately 1.75–2.5 inches. It is well suited for trail, all-mountain, enduro, and general off-road riding when a reliable basic inner tube is needed for a variety of tire widths. The 42 mm Presta valve works particularly well in standard mountain bike rims that do not require an exceptionally long valve.

The inner tube is designed for 27.5 x 1.75–2.5" tires, and the product specifications typically list the size range as ETRTO 47-584–62-584. The butyl construction makes it a good choice for daily riding, as a spare in a backpack, or as a reliable alternative inner tube for mountain bikes. Continental's seamless, vulcanized construction supports consistent quality and roundness during use.

The 42 mm Presta valve fits most standard mountain bike rims. Several product listings also mention a removable valve core, which makes it easier to add sealant or perform maintenance as needed. According to retailer information, the weight ranges from approximately 200 to 235 grams.
