Teravail Standard Tube - 20 x 2.8 - 3 | 35mm Schrader Valve

What Tube Handles 20-Inch Plus and Fat-Style Tires?

The Teravail Standard Tube line covers the 20 x 2.8-3.0 inch range, fitting the wide, high-volume tires found on 20-inch fat-style bikes, cargo build kids' bikes, and oversized recreational 20-inch setups. The 35mm Schrader valve handles low-pressure inflation simply and reliably using any standard pump, making this the right choice for a wheel format where you want easy maintenance and zero complications. Fat-adjacent 20-inch builds are uncommon enough that having a spare on hand isn't a luxury, it's a necessity.

Teravail's butyl rubber construction fills out wide, high-volume 20-inch tires evenly at the lower pressures these builds typically run, without the bunching or uneven inflation that affects budget tubes in this format. The 20 x 2.8-3.0 range is a specialty size that sits between standard BMX and true fat bike territory, and the consistent quality Teravail brings to every tube in the lineup means this niche size gets the same production standards as the most popular road tube in the catalog. If your 20-inch build runs wide rubber, keep one of these in the kit.
