Teravail Standard Tube - 26 x 1.75 - 2.35 | 40mm Presta Valve

How Does the Teravail Standard Tube Serve 26-Inch MTB Riders?

The 26-inch mountain bike format may be the veteran of the wheel size conversation, but it's still in active rotation on millions of bikes worldwide, and the Teravail Standard Tube line keeps it fully supported. Sized for 26 x 1.75-2.35 inch tires with a 40mm Presta valve stem, this tube covers the most common trail tire widths in the 26-inch format with the Presta valve preferred on quality alloy and higher-spec builds. The 40mm stem length is well matched to standard double-wall alloy 26-inch rims, providing clean pump head access without the excess length of a 48mm stem on a rim that doesn't need it.

Teravail's butyl rubber construction holds trail pressures reliably between rides and resists the slow leakdown that forces last-minute top-offs on bikes used for regular trail riding or commuting. The 26 x 1.75-2.35 range covers the widest spread of useful 26-inch trail tire widths, from faster-rolling 1.75 XC profiles to fuller 2.35 trail tires, making this one tube a dependable option for most 26-inch builds without needing to match an exact tire width. For any 26-inch Presta build on the trail or the commute, this is the tube that earns its place.
