Pair of Mavic Yksion PRO UST 2. Tubeless. ETRTO 28-622. Rim min 17c. Rim max 23c. Never used, still packed as delivered (came with bike last September, I paid extra for tubed tyres). Opened one to see what it was so bit of dust from garage floor. Assume they will be of interest to serious cyclists so could you tell me what plastic clips in separate photo are for?
