FISCHER bicyklová duša 28 inch Dunlop ventil 35-622 až 47-622 ETRTO 85103

This FISCHER bicycle inner tube is a dependable replacement for 28-inch wheels, built to fit a range of tyre widths from 35 mm to 47 mm. Its butyl rubber construction delivers excellent air retention, so you spend less time pumping and more time riding. The Dunlop valve (DV) with metal stem and threaded design ensures a secure, leak-free connection, and the included valve cap keeps out dirt and moisture.

Advantages

The FISCHER inner tube offers a perfect balance of durability and everyday practicality. Butyl rubber is known for its superior air-holding properties compared to natural rubber, meaning your tyre pressure stays stable for longer. The Dunlop valve is widely used on city, trekking, and hybrid bikes across Europe, making this tube a straightforward swap for most standard rims. Its metal valve stem resists bending and corrosion, while the threaded base allows for a firm pump head attachment.
