Did you know about a product called Vittoria Pit-Stop? These are, quite possibly, the most beautiful words I have ever read:
Vittoria Pit Stop is a pressurized cylinder filled with compressed gas and polymer foam sealant. You carry the cylinder with you in a bike bag or jersey pocket. When you have a flat tire you simply open your valve stem, press the nozzle on the Vittoria Pit Stop canister onto your valve stem and press toward the tire to release the compressed gas and the liquid foam sealant. Both substances shoot into the tire under pressure. The gas inflates the tire while the foam sealant flows into the puncture and instantly dries, sealing the hole and fixing the flat.
I'm sitting here thinking--are you kidding me??? Something like this exists and might work???? And I didn't know about it????? You don't need to take the wheel off (think the rear one), or use any tools! If this isn't intervention from the Divine, I don't know what is. On top of everything else, I've heard from a couple of people that it actually works!
Yes, I can change a flat, but I really don't want to in an Ironman, or any race for that matter. It gets even more complicated when you have bad close up vision. I don't need glasses for far away, but I can't see the details of tire changing very well. I just refuse to carry a pair of "readers" in my tool bag!
This could be the stuff that peaceful dreams are made of. I, for one, am ready to lose the race-day-flat-tire nightmares. I'm going to give it a try and report back.
Here's the review I read at Bike Sport Michigan.
I also welcome any other suggestions that have changed your cycling life!
