Quick Summary
The Schwalbe Impac inner tube is a black 20-inch tube with a 35 mm Schrader valve. It is listed for 20 x 1.75, 20 x 2.00, 20 x 2.10, 20 x 2.25 and 20 x 2.35 sizes, so the main buying check is matching the tyre size and valve type.
For a replacement tube, the tyre marking and valve style matter more than the colour. Check both against the wheel and tyre you already have before choosing an offer.
