Description: Made from a very special Micro Closed Cell Polymer Resin “Aither”, Tannus tire uses a foaming technology. Adn, it may look similar to that used in many lightweight sports shoes, but it is totally different from any other foaming technology both in terms of its process or the condition. It is made from the one-and-only material “Aithercompound” with a very unique foaming process. Aither1.1 had much enhanced elasticity than Aither1.0, ensuring a better feel whilst riding and good grip performance.Furthermore, Aither1.1 is performing at a much lower rolling resistance-approximately 15% less. It now has the rolling resistance rate that closely matches premium pneumatic city bike tires, taking this a step closer to ideal bike tire. Item include: 1 x Tannus Locking Installation Pins ,1 x Tools,1x Black Tyre Breakthrough Tire Technology With technology advancing so quickly it’s surprising that tires have remained overlooked. Our quest was to create a lightweight material that rides and reacts the same as a regular tire but that will never go flat. The patented Aither technology that makes up 100% of our solid tire is an engineering marvel. This material is resistant to wear and tear and still provides comfort, minimizes rolling resistance and provides a safer experience. All these benefits come with that knowledge that our tires are environmentally safe. Price for 1 pcs The Urban Bike Pte.
