Blackspur Bicycle Inner Tube 27.5" x 2.1"-2.5" Schrader Valve

The Blackspur BB-BK110 Bicycle Inner Tube is a durable replacement inner tube designed for 27.5-inch bicycle wheels with tyre widths between 2.1" and 2.5".

Manufactured from puncture-resistant butyl rubber, the tube is designed to provide reliable performance and good air retention for everyday cycling. It features a 33mm Schrader valve, making it compatible with suitable bicycle wheels designed for this common valve type.

The inner tube is supplied flat packed for convenient storage, making it useful as either a direct replacement or a spare tube to keep at home or take with you when cycling.

Before fitting, always check that the tyre, wheel and rim tape are in good condition and confirm that both the tube size and valve type are compatible with your bicycle. The manufacturer recommends that the inner tube is inflated using a hand pump only.
