The Continental MTB Tube Wide 29" S42 RE is a reliable inner tube designed specifically for modern 29-inch mountain bike wheels. Built from high-quality butyl rubber, it offers an excellent balance of durability, air retention, and flexibility, making it a great choice for everyday trail riding, training, or commuting on your MTB. The “Wide” designation means it is suitable for a broad range of tire widths commonly found on 29er mountain bikes, giving you the versatility to run anything from faster rolling XC tires to more aggressive trail or all-mountain treads.
Equipped with a 42 mm Presta (S42) valve, this tube is compatible with most MTB rims and works well with both standard and many tubeless-ready rims used with tubes. The valve length is ideal for typical mountain bike rim depths, making inflation straightforward with floor pumps or mini pumps on the trail.
