Valve Extender Question

Postby dino019 » May 11th, 2012, 5:34 pm

I have a 60/90 set of wheels arriving in a few weeks & I'm trying to decide on valve extender length. Currently my wheels are both 40mm. So I use tubes with a 60mm presta. Would I be okay just getting a couple of 42mm Topeak valve extenders? To me, that seems perfectly fine option for both wheels. I ask because Topeak says that the 42mm extender is only for wheels 60mm and under. They do make a longer extender.....73mm. But putting a 73mm extender on a 60mm presta, for my 90mm rear, seems like overkill to me. Plus it would make training/rides easier if I could with similar part lengths.........instead of carrying 2 different tube lengths & 2 diferent extender lenghts.

Thoughts?? Opinions??

I would imagine you would be be ok with the 42mm extenders. It may be a little close but I'm guessing you would still be able to get your pump on the valve. I understand the desire to train with one tube for each tire! Here is a quick video we put together on valve extenders...

Please let me know if have any additional questions.

All the best,

Hi Chris and Jon,

On the topic of valves, what length valve stem do you recommend for the Flo Disc? I'm hoping to pull the trigger on one in Pre-Order 2 and am tossing up between a few different brands of latex tubes which have different length valve stems. Need to strike that balance between being long enough to poke through the rim and short enough to fit the pump crack pipe (or even pump head if possible) in the hole!

Cheers.

You should be fine with a 32mm valve. That should give you enough room to fit the head of your valve in the cutout.

Please let me know if you have any additional questions.

Take care,
