tubed tyre- valve collar?

synthasandwich

Hi All,

Firstly, thanks for reading- I still class myself as new to all this so please help if you can.

I have put my old tubes and tyres on some new rims a few months ago, installing some new tough rim tape- I think the brand was BBB. When I changed over a little plastic collar flirted out from around the Schrder valve and I just wondered what it is called and if it is important ( as I lost it. )

a couple of problems have now arisen:

1) a leak around the valve- I have recently had the tyres off again and I think I got a pinch on but is the lack of this tiny plastic collar an issue as the valve is against the bare metal hole?

2) I seem to have damp underneath the rim tap- had a couple of loose spokes but again, am wondering if it the lack of this collar for a flush fit.

Any advice gladly recieved, too skint to keep knackering tubes. Cheers

The plastic collar reduces the hole down from Schrader (car type) to Presta (thin type).
The leak will most likely be a pinch and the dampness due to water ingress around the valve. The spokes shouldn't be effected.

Cheers Craig XXL,

Reassuring stuff- Not too much damage done. I'm going to try the talken powder trick from the beginners guide to avoid the next pinch, bloody annoying- I feel a bit amateurish.

Weird thing is that the collar flirted out from the original Schrader tubes on the original tyre. Couldn't understand it because I don't think my new rims could get the collar and the Schrader valves on when inflated, although the valve does sink when the tyre goes flat- I think possibly this is how the water has gotten in, that or the loose spoke.

Thanks for the link though- it does seem to be this part- it was a plastic shape like that.

Mark.
