As the racing seasons for many championships get underway, it is worth taking a moment to give thinks we still have them and consider why we like motorsports. Simply put, these are the things I love about racing.
The Big One
Starting the season with your biggest race may seem odd to some people, but could you imagine NASCAR without Daytona coming first? Heck, no. The Super Bowl of stock car racing is an epic race and the Big One is as well. This year's race was a bit anticlimactic, but what can you do when it rains? Still, the Big One is definitely something that has to be seen.
Monaco Rally
Most racing fans in the United States don't know squat about the World Rally Championships, better known as WRC. Well, you're missing out. It is insane. Imagine cars flying down twisty roads with the fans standing on the side with no barriers. They crash into trees, walls, roll down cliffs and, well, you get the idea. Any of the races are good, but Monaco is insane. The last one I saw ended up with one car crashing going around a corner so badly it ended up hanging off a cliff. Even the cars that pull it off do so with a white knuckle ride you can't imagine.
Indianapolis 500
Duh. The powers that be in open wheel racing in the United States have done everything possible to ruin the sport. Once, it was as or more popular than NASCAR. Hard to believe, huh? Well, the open wheel civil war is finally over. There were no winners. One group just ran out of money before the other. Despite these morons, the Indianapolis 500 still is one of the great races in motorsports. Plop yourself down on the couch and take the time to enjoy a classic.
Malaysian Grand Prix
Formula One is all about huge money and incredible technology. More often then not, the Malaysian Grand Prix renders it all useless. Malaysia gets some insane rain storms. Formula One visits the country early in the race schedule when rain is often due. When it rains, it pours like God is trying to flood the world. The cars go sliding across the track, the fields and slam to and fro. Imagine a huge sheet of ice and cars trying to drive on it. It is hard to describe, but absolutely hilarious.
There's plenty to love about motorsports. Everyone has a favorite, but make sure to give all the championships a try. There's something to love in each one. Let the seasons begin!

The Anatomy Of A Mountain Bike
There’s a lot of terminology to learn if you’re a mountain biking enthusiast. These enthusiasts have a language all their own, what with “face plants, boing-boing, drillium and wild pig.”
However, there is also biking terminology that stays the same, regardless of the age of the user, and that’s the terms used for individual parts of the bike. And its important to know these as well.
1. Bottom bracket – A circular hole in the bottom frame of the bike, used to attach the crankset.
2. Brake cable – The cable that connects the brake lever to the brake mechanism.
3. Brake lever – Lever on the handlebar which activates the brakes. The left lever controls the front brake, the right lever controls the rear brake.
4. Chain – The set of circular metal links which transfers power from the chain ring to the cogs. There are two types of bicycle chains: bushing and bushingless.
5. Chainring – Part of the crankset. A sprocket or toothed wheel which attaches to the crank and holds the chain. Bikes can have from two to three chainrings.
6. Crank – Part of the crankset. The lever or “arm” which connects the pedal to the bottom bracket.
7. Derailleur – The device which moves the chain from one chainring to another inorder to shift gears.
8. Down tube – Part of the frame. The tube which runs diagonally from the head tube (supporting the handlebars) to the bottom bracket. Above this is the top tube, which runs from the head tube to the seat.
9. Front shock – A suspension system on the front fork which allows the bike to absorb shocks without transmitting them to the rider.
10. Handlebar – The horizontal bar located at the front of the bike which is used to steer, and which will contain the shifters and break levers and any other items a cyclist wishes to have within easy reach.
11. Headset – The device which houses the bearings that enables the handlebars and front wheel to rotate on the frame of a bike. There are two types of headset, the threaded and the threadless.
12. Hub – The center part of the bicycle wheel, consisting of an axle and ball bearings to allow the wheel to move easily. In addition, the spokes radiate out from the hub to the bicycle rim.
13. Idler pulley- A pulley takes up slack in the chain in order to keep it tight at all times.
14. Nipple – Small threaded cylinders in the bicycle rim which secure a spoke to the rim.
15. Pedal – A short metal bar on which to put your foot, in order to propel the bicyle. The pedal is attached to the crank. Pedals can be simple or come attached with clips in which to put your shoes to increase leverage.
16. Rear shock – On a dual suspension bike, the device that absorbs shocks from the rear tire.
17. Rim – The metal ring to which the bicycle tire is fitted, and to which the breakes apply their force. The interior of the rim holds the spokes which give strength to the tire.
18. Saddle – Also called the seat. Something to sit on!
19. Seat post – The tubular support to which the saddle is connected. This tube is then placed into the seat tube, and can be raised or lowered depending on the rider.
20. Skewer – A metal rod that attaches the wheel to the frame of the bicycle. On one end is a nut to keep the skewer secure, on the other is the release mechanism, which is secured either by a “quick release” toggle, or with bolts.
21. Spindle – Part of the bottom bracket. The free rotating axle to which the crank arms attach.
22. Spokes – The thick wires that join the hub to the rim. The amount of spokes determine how strong the tire will be. Spokes can also be arranged in different patterns, which affect twisting and brake forces.
23. Stem – The metal piece that attaches the handlebar to the steering tube.
24. Wheel hub – See hub.

7 x 2 speed shimano 600 sti?
I recently bought an early 90s specialized epic with full shimano 600. There is some lateral play in the 7 speed cassette, and the rear skewers are on really tight. The cassette clunks due to the wiggle room. The brifters index 8 times, so I'm a little suspicious that the rear dropout spacing is really 130mm and not 126mm.
A friend is offering a nice 8 speed wheel and cassette for $30.
Would I experience compatibility problems, or did shimano 600 (6400, sti) always use 8 speed cassettes anyways?
Rear spacing is the space between the rear dropouts, all you have to do to measure it is to remove the rear wheel, and measure the space from the inside of one dropout to the inside of the other. Your loose cassette has nothing to do with rear spacing, you need to have the rear hub serviced. If the brifters index 8 times, they may be 8 speed, so you could possibly install an 8 speed cassette. You would have to check to see if your cassette body is 8 speed compatible when you have the wheel serviced. If the cassette body can't accept an 8 speed cassette, it would have to be changed. If your shifters are indexing correctly with a 7 speed cassette, they won't work with 8 speed, the spacing between cogs is not the same. The bike shop where you have the wheel serviced will be able to tell you whether your bike is 8 speed compatible.
