This XLC road bike specific inner tube VT-D28 provides quality puncture protection when you need it most. It is suitable for bikes with a wheel size of 28" or 700c most commonly found on road and race bikes, and the following tyre widths, 27/28 x 1, 1/8-1.75 and 28/47-622/635. Unlike other tubes, this product uses a Dunlop valve. This is one of the most common valve types across Germany and the Netherlands, and are secured with a lock nut and can be exchanged quickly without tools.
