Riders on 29 x 2.1 to 2.3 tyres who want a simple, dependable butyl tube for a puncture swap or a spare.
The SporTUBE is Pirelli's classic butyl inner tube, the standard way to hold air without any fuss. This one is made for 29 x 2.1/2.3 tyres (ETRTO 52/58-622), so it matches 29er tyres marked between 2.1 and 2.3 inches wide.
It has a 48 mm Presta valve with a silver stem and weighs 210 g, according to Pirelli. It works with both disc and rim brake wheels, which makes it an easy spare to carry or a straightforward swap when a tube is punctured or worn.

Tube
Fit and use
Great for
Maybe not for
This tube is for 29 inch (622) wheels and 2.1 to 2.3 inch tyres. Check the size printed on your tyre's sidewall, and check that the 48 mm valve is long enough to reach through your rim.
Match the size and the valve
A tube is picked by two things: the wheel and tyre size printed on your tyre, and the valve your rim is drilled for. This one covers 29 x 2.1 to 2.3 with a 48 mm Presta valve. If your tyre reads 2.4 or wider, Pirelli makes a separate 29 x 2.4/2.6 SporTUBE, so pick that size instead.
