Just 35 g against the 150 g of a rubber tube: less weight on the wheel, less rolling resistance and more speed. It takes up far less space and comes along on every ride.
The IMPALAPRO 35 g is a TPU road bike tube for 700x25c and every 700x18-32C tire, with a 0.25 mm wall: it holds pressure far better and stands up better to heat and punctures. Semi-metal Presta valve in 45, 65 or 85 mm.
The 35 g tube has a 0.25 mm wall (the 28 g, 0.2 mm). It holds tire pressure much better and copes better with heat and punctures, in exchange for 7 g more.
Yes. It fits 28" (700C) road bikes with 18 to 32C tires: 18, 23, 25, 28, 30 and 32C, so it works as a 700x25c or 700x28c tube.
A semi-metal Presta (French) valve in three lengths, 45, 65 and 85 mm, so you can pick the one that suits your rim.
Yes. It's compatible with disc brakes and standard rim brakes.
Inflate it to 30 % so it takes shape, without going over 6 PSI, put the valve through the rim and spread the tube inside the tire without pinching it. Then finish inflating to the recommended pressure for your road tire (usually between 90 and 120 PSI).
35 g, against the 150 g of a standard rubber tube. It also takes up far less space.
