• Look at the valve hole in your rim: Small hole(approx. 6.5 mm): Choose theSV17(Presta).Big hole(approx. 8.5 mm): Choose theAV17(Schrader). This is common with city bikes and mountain bikes.
• Select the correct valve length:For standard rims, 40 mm is sufficient. For higher rims (especially on racing or trekking bikes), choose a longer valve of 50–60 mm.
