VeloTubes Premium Tubeless Presta Valve Stems (40mm or 55mm) - Integrated Core Removal Tool, Grommet Options - Choose Color.

VeloTubes Alloy Presta Tubeless Valve Stems are designed specifically for use with tire inserts like CushCore or Tannus Armour, however, they can be used without inserts as well. The base is larger than most stems to accommodate a wide variety of rim designs, and the air/sealant flow is from the side and bottom of the valve so that the insert does not block the flow. The cap has an integrated core removal tool. The stem, nut, and cap are all made of 7075 aluminum. They are tried and tested to be top quality. They are lightweight due to their alloy construction and very sturdy. Available in Black, Red, Blue, Gold, Green and Purple and in either 40mm or 55mm length. Compare to name brands! Each stem includes two grommet options, a lock nut, cap, and a rubber O-ring. Weight: 6 or 7 grams depending on size.
