Reviews over the

Pirelli PZero SmarTUBE

I managed to get a flat on a ramp just by putting too much weight on the rear wheel. The tube just didn't hold air anymore, and I got a rapid pressure loss. I guess if you are careful not to stress the tube too much it won't happen to you. But it can be a bump or a pothole that causes this, which is something that won't happen to a classic tube. Better carry on wheel extra 70-80gr rather than pay 5-6 times more for a bit of weight advantage with this kind of risk.
