Performs well, eco friendly, great puncture protection.
These inner tubes are a more recent alternative that have the characteristics of both plastic and rubber.They are mouldable like plastic, and flexible like rubber.The reasons I would choose to use these particular inner tubes are many, but chief among them is the reduction in weight and rolling resistance, while at the same time they increase the protection from punctures.They are also a really eco friendly option as they can be easily recycled for other uses at the end of their life.If you are a rider who like myself is looking for great performance and a puncture, and hassle free ride over uneven ground, I would recommend them.They are no more fiddly to install than any other, and have lasted me well over notoriously bad ground when I tested them.I hope you find my review helpful.
