Have you ever wondered how to quickly adapt your wheels to other driving conditions without changing the wheel? Well, there is a solution - zipper tires! You do not need to replace the wheel, but you need to replace the tire with a special base with a slider, on which you can normally ride or attach the right "skin" intended for a given area, which takes several seconds, because you do not need to remove the wheel. It is hard to find an easier method, which will be useful not only for more sporty cyclists, but also for most winter cyclists who would like to change into special ones for snow and ice tires with metal lugs, on which there is no fear of a rollover, if only you have them two wheels. The reTyre company comes to our aid here, which produces various zipper tires from 26-29 ", including those for snow and ice with metal studs:
