Cool Tools pointed out a neat set of bike tire repair tools called the Genuine Innovations Deluxe Tire Repair & Inflation Wallet. For about 25 bucks, you get:
- an Ultraflate Plus CO2 cartridge-based bike tire inflator,
- three 16g non threaded CO2 refill cartridges,
- a small bike tire patch kit,
- a 3.5 x 4.5" nylon bag with a zipper
All of this fits in your bike seat bag. The Ultraflate works with Schrader or Presta-valved tires.
Genuine Innovations has a broad line of tire repair kits for cycling as well as Motorcross and ATV that's available directly through their website. Their products are also available at dealers throughout North America.
I think these kits represent a good value if you're buying accessories for a friend or relative getting a new bike. Most people don't realize that they're going to need all of these tools when they first purchase their bikes. It only takes one flat to make you realize that you need a complete set of tools with you on every ride and you need to know how to use them.
