Why not a combo with the RVC extensions?
I will never buy non threaded valve extenders again, because threaded ones work for tubeless use while unthreaded don’t. I have now learned this (obvious) lesson twice when going to do a deep wheeled road tubeless setup...there I am with my big bag of every length of valve extender on earth, including a dozen of those RVC ones you get with the old rim braking wheels, and none of them work for the tubeless task at hand.
Besides that, Josh is on here telling everyone to use tubeless tape, which I sort of agree with, but his RVC extenders are, in my experience, nearly impossible to push through tubeless tape and through the valve hole without the little rubber jawn getting all scrunched up...so then you have to remove it, defeating the entire purpose of that extender. I hate that product for this reason and for the reason that if you don’t use butyl tubes anymore for any purpose ever, which I don’t know why you would, then none of the extenders are the right length in the hole (with Vittoria latex).
Josh has explained why this is but to me this new solution of coming out with a slightly different length latex tube valve is coming at the problem from the wrong angle. Why not give us this tube with 80mm and 100mm valve lengths? Nobody wants to use extenders. Dealing with extenders is just another unnecessary piece of kit complexity and an unnecessary point of failure for race day.
So that leaves me two reasons to buy this product:
a) it’s the only option on the market that (ostensibly) provides a discount, via the bundle, on the kind of valve extender I increasingly need to use for tubeless setup. I just bought a bunch of these so that all the short tubeless valves I have can actually be used with modern wheels.
b) This “optimized for wider tires†claim. Somebody is going to have to have to help me understand how a tube made for 24 to 30mm does anything for me. Yes my tires inflate to 26ish on Zipp and 27ish on Enve and on the HED Vanquish or Enve 4.5 AR it's more like 29-30, but I still don’t get the optimized thing. Is there really a material difference in longevity of the tube optimized for 24-30mm (Silca) vs. 25-28mm (Vittoria classic)? I don’t believe it.
Somebody should make 80mm and 100mm valve lengths on these tubes. Big missed opportunity for Silca in my opinion, and there is no problem this new offering solves for me unless there's a mega discount on those threaded extenders.
