Hold Fast Insert Compatible Tubeless Valves

The Hold Fast Insert Compatible Tubeless Valves come in 42mm and 65mm lengths and are sold as a pair. Choosing between them comes down to rim depth: add at least 15mm to your rim depth, which leaves room to get a pump head on. A 25mm-deep rim wants the 42mm valve, and a 50mm-deep rim wants the 65mm. If your rims are deeper than 50mm, look at the separate 80mm and 105mm Hold Fast valves instead.

The cores are removable and the bases are replaceable, so the valve can be serviced rather than thrown away. The core tool caps in each pair double as a valve core tool. These tubeless valves work with all tire inserts, CushCore and Airliner among them, and can also be used without one. Color is chosen per valve from 16 options, so you can match the pair or mix them.
