I race on a Zipp disc rear and a 808 on front. I ride an "older" 2013 SC with a skinnier draft box than the newer ones, so it really only has room for one tube with all the other stuff (tire levers, CO2, multitool, etc). My question is how should I set up my spare tube for racing given that the 808 will require a longer valve/extender, but the disc requires a shorter valve? Here are my options as I see them:
I guess it's obvious that the third option is ideal. If I can't get that to work, what would you do?
Here's to hoping that none of this matters.
- Keep my spare tube at the shorter valve length, assuming that a rear flat is more likely than a front (don't know if that is a valid assumption). Pack a valve extender with a valve core already assembled. If I get a front flat, I'll have to unscrew the valve core from the spare tube and screw on the extender before changing the tube.
- Setup the spare tube with the valve extender on, and pack a spare valve core. If I get a rear flat, I will have to unscrew the valve extender and screw in the spare valve core before changing.
- Try to find another place out of the wind to pack another tube. Perhaps zip-tied under the rails of the saddle?
- Maybe try to find more room for another tube in the draft box by not using the thick neoprene bag that goes in it. That would make it tricky to pull everything out. It also might cause more noise which would drive me nuts.
