STANS NOTUBE is a brand based in New York, and is a leading company that plans and sells tubeless ready (semi-tubeless) bicycle tires and their accessory parts.
Use tape of a size that matches the width of the inner surface of the rim. If the tape used is too narrow or too wide for the inner surface of the rim, the airtightness will not be maintained and air leakage may occur.
The 26-inch length is about 5 pieces, and the 27.5 and 29-inch (including 700C clincher) lengths are 4 pieces. The rim tape is applied from 10 cm ahead of the hole so as to cover the valve hole. When you finish pasting, double cover the valve hole and cut it 10 cm from the hole.
