Hi,
I am using the Cyclocross rim strip to try to convert a Fulcrum Racing 5 700c wheel to tubeless, using a Schwalbe Racing Ralph tyre. I have installed one layer of No Tubes rim tape underneath the strip.
The problem I am encountering is that the tyre inflates and holds air, but as soon as I remove the pump head to reinstall the valve core the tyre falls off the rim, i.e there is no tight seal.
If I try to inflate with the valve core still in the wheel I am able to get the wheel to inflate and it does hold air. However, it is possible to push the tyre back from the rim, indicating that it isn’t properly seated. If I then deflate the tyre it then falls away from the rim bead (there was never a ‘pop’ in the process and I have used lots of soapy water in the process).
So, the problem I have is that the tyre does inflate but just doesn’t want to form the ‘lock’ on the rim. Any thoughts on what could be the issue and how to remedy it would be very appreciated!
