Retail Price: ¥1,870 A tool born in England for replacing inner tubes. Dealing with stiff tires that are difficult to fit, or the dreaded pinch flats when inflating the tube. The Tire Key is a tire changing tool that prevents these issues. It's very easy to use. Plus, the tube won't get caught between the tire and rim, eliminating the worry of pinch flats. It can be used on both aluminum and carbon rims. I have multiple units available, so please comment if you wish to purchase more than one. I will discount the shipping cost. Road bike Cycling Bicycle
