Help needed with valves/extenders for 60mm carbon wheels

daniel_b

Hello all,

recently via a thread on here I ordered some 60mm carbon wheels.

Having recently come back from holiday I thought I should fit the cassette and fit the tubes and tyres.

Popped the cassette on no problems, but the 60mm tubes I bought do stick through the rim, but not far enough to inflate it :oops:

The tubes I bought in anticipation are Continental 60mm valves, and the other ones I have are the 42mm for usual wheels.


What confuses me is this - the LV ones seem to be designed so the top section can screw out of the tube altogether, which I think means I can buy extenders to increase the length?

But I only need 10mm or 20mm at most, so I thought well that's fine, I can use the 42's that I have plenty of, and buy a 40mm extender, job done - however the 42's seem to be fixed and do not have this functionality.....

So can anyone shed any light on what my best route forward is please?

Am I correct in thinking that my best route will be to use the 60mm valve tubes, unscrew the top bit, put an extender in such as:

And then am I meant to screw the top of the valve into the extender - is that how it works?

Or what about this one?

What are my other options, if any??

Quite dissapointed as was keen to get them up and running but hey ho.

Also a bit bizarre that the longer ones have a removable core and the short ones do not, I can't see any mention on the ribble site of a tube being available like the 60's I have.

So am I best to get some kind of extender for the fixed and cheaper 42mm valves, or do I need to get an extender for my small amount of tubes with removable cores?

Would appreciate your input :-)

Cheers

Specialized do 80mm valves if you don't want to bother, so do Conti if you look.

I though use a Topeak extender with my latex tubes, got mine at Evans (but I have one only 1.5 mils away from me, so its convienient)

I first tried with a brass extender and I didn't get on with it at all; in fact I ended up overnflating two tubes.

Some tubes do seem to have removable cores, others don't
Quick look on Wiggle site shows a fair range of valve lengths, Vittoria do an 80mm one, Zipp do extensions of 27/33/48/74/100mm (use Zipps on my tubs) , SRAM do 33/48/72.
For my tubs it was a case of unscrew the valve and screw the extender onto that but inner tubes may be different, core may need removed ?
