Excellent
Perfect for putting on your Presta valve mountain bike tyres, so you can use your Shrader valve pump. Remove after use and reseal your Presta valve. Don't leave on whilst cycling.

Too short for a tyre inflator to seal around them.
They screw nicely onto a Presta valve, however the Schrader end is too short to attach a tyre inflator to. It would not make a seal and just blew air around the outside of the valve without any actually going in. If you made the Schrader end longer they would be perfect. As they are right now they are as much good as a chocolate tea pot.

On my bike
Excellent product, not used my bike in years due to not being able to keep the tyres inflated properly. That has now all changed and I’m back on my bike
