Say you want to carry one tubular spare in case of a flat during a race. Your front wheel is super deep dish (zipp 808 or blackwell 100), and your rear wheel is a zipp 404 w/disc cover and PT SL. Both tires would need a valve extender; however, the super deep dish would need a longer extender. How do you prep for this situation?
Thanks!
The shorter extender won’t do much good on the deeper rim, and a little extra extender never killed anyone, so I’d go with the long extender. If the longer extender is too long for the rear wheel then bring two extenders and put on whichever one you need.
I race on a front 808 and rear disc. The 808 needs a looooong extender, and the disc needs a crack ipie to be pumped. I use electrical tape to attach both to my bike (I tape them to my x-lab flatwing). Then, if I need one, I just grab it and am good to go.
