56 g in 26", 60 g in 27.5" and 66 g in 29", against the 150-200 g of a rubber tube. Less rolling resistance on any terrain and far less bulk in your pack.
The IMPALAPRO MTB is an ultralight TPU inner tube for 29, 27.5 and 26" wheels, from 56 to 66 g depending on size: less rolling resistance and better puncture resistance than a rubber MTB tube. For 1.75 to 2.4" tires, with a 45 mm Presta valve and a removable core.
Three wheel sizes: 26, 27.5 and 29 MTB inner tubes, for tires from 1.75 to 2.4" wide. Each in a pack of 1 or 2.
56 g for the 26", 60 g for the 27.5" and 66 g for the 29", against the 150-200 g of a traditional rubber tube.
A 45 mm semi-metal Presta (French) valve with a removable core, in all three sizes.
Yes. It's compatible with disc brakes and rim brakes.
Inflate it to 30 % so it takes shape, without going over 6 PSI, put the valve through the rim and slide the rest of the tube inside the tire. Refit the tire and inflate to the recommended pressure.
Ideal. At 56 to 66 g they weigh a fraction of a 150-200 g rubber tube and take up far less space, so they disappear into your pack or saddle bag.
