Yellow rim tape is thicker than black rim tape. 
Yellow tape seals the rim without the need of any other type of strip or rubber band, with just 1 round, adding only 6-7 grams per wheel.
9 meter roll of yellow tape make tires tubeless-ready. One roll provides enough product for 4-5 wheels depending on the tire size.
Carefully clean the rim channel before gluing tubeless tape.
