Peaty's x Chris King MK2 Tubeless Valves
The Peaty’s x Chris King MK2 Tubeless Valves merge Peaty’s practical, service‑oriented design with Chris King’s legendary precision machining, producing reinforced aluminum stems with proprietary threading and premium sealing for the highest‑pressure e‑bike use. They are the market’s premium option — commanding the highest price — but offer unmatched finish, corrosion resistance, and long‑term reliability compared with the other stems listed, making them the preferred choice for riders who prioritize absolute durability and low lifecycle cost. For users who treat valve failure as unacceptable, the MK2 is the technical and financial leader in total‑cost‑of‑ownership terms.
