A pair of disposable latex gloves:  Not absolutely necessary, but good for keeping grease and grime off your hands during a repair.  Also, nice to have in an emergency when it starts raining and the temperature drops 20 degrees and you don’t have a pair of regular gloves.   Just keeping your hands dry and the wind from directly blowing on them makes a huge difference in comfort.
It includes nine tools: seven hex bolts, one torx bolt (the star-shaped one), and a Phillips screwdriver (also the star-shaped one). Like Peter says in our guide, if you have a newer mountain bike or road bike it pays to take a quick look at what types of tools you need, as torx bolts are becoming more common. And a quick glance at the bottom of your shoes or derailleur bolts will confirm if a Phillips head is the right choice.
The thumb test is the fine art of pressing on the tube with your thumb to see if it’s inflated. During testing, I took a pressure reading out of curiosity, and to the touch, road tires feel fully inflated around 30 psi. How pathetically sad—30 psi!—when you’re probably trying to reach at least 60 psi on a mountain bike, 70 or more on a hybrid, and it only goes up from there.

Since then, I’ve found a few decent alternatives to my dilemma: The Venzo Pro Mechanic Stand that runs at about $88, and the Cave Competitor Service Post for $59. While there are other alternatives out there—sometimes cheaper ones—these are the two that I think are actually worth the price. I can’t really vouch for any others out there. But there just ain’t getting around this one. You’ll need something to hold your bike while you work on it.

Whether you ride a single, 7, or 10 speed bike or anything in between, you will need a slightly different chain. The major difference is that they come in varying widths to accomodate the different spaces between the gears, but quality of construction is also a factor in choosing a chain. Inspecing the chain should be a part of your regular cycle maintenance procedure- It’s important to keep a chain well lubricated, but oil will also attract dirt and so different oils for specific riding conditions are available. Remember to clean your chain regularly to get the longest life out of it and the gears.
