If your wheels have Schrader valves and your pump hose has no integral chuck, you need the Schradero Chuck Hose Barb. It can be inserted, then secured with a Jubilee clip, for instant Schrader valve compatibility.
The long, graduated stem of the Schradero Chuck Hose Barb, together with its synthetic elastomer face, will ensure that a reliable seal is formed with your valve, making each pump stroke effective, with little or no air loss. Then, when you're done, a quick-release sleeve will let you easily detach the pump again.
No leaks means little or no movement as you pump, so your high grade aluminium chuck will likely last you a lifetime. However, should manufacturer defects become apparent in the first two years of use, it is covered by Silca's Limited Warranty for your peace of mind.
