Mountain Bike Anatomy - 50 parts in 5 minutes

This is a mountain bike, and at the heart of any bike is its frame. Lets start with the parts of the frame. This here is the top tube, the down tube, the seat tube, the seat stay, and the chain stay. This area down here is called the bottom bracket shell. At the very front of your bike is the head tube, which houses the steerer tube. This moves smoothly thanks to a set of cups and bearings collectively known as the headset. Above that are headset spacers and the stem. The stem, which clamps on to your handlebars, is fastened to the steerer tube with a top cap and pinch bolts. On your handlebars youll find brake levers, shifters, grips, and end plugs. All this stuff up here is collectively known as the cockpit. \r
\r
Moving down is your fork, which in this case is a suspension fork. This top piece is called a crown. Some bikes are fitted with dual crown forks for added strength. The crown is what holds your stanchions, which you should try as hard as possible not to scratch. Dont hang your bike by the stanchions.\r
\r
Down here is your brake caliper, which camps down on your rotor when you squeeze your brake lever. Some calipers are mechanical, while others are hydraulic. Hydraulic brakes push fluid through a hose, while mechanical brakes pull the caliper using a cable. \r
\r
This big round thing is a wheel. If you buy a front and back wheel together, its called a wheelset. All the parts of your wheels are held together using spokes, which connect to your rim with these little guys. Theyre called nipples. Also on the rim is a valve stem which is used for pumping air into your tires. At the center of the wheel is the hub, and inside the hub are bearings. The hub rotates around an axle. On a lot of mountain bikes this takes the form of a thru axle, which can be removed or installed by hand.\r
\r
On the rear wheel a cassette hub. This has a ratcheting mechanism built into it which is made to accept a cassette. The cassette is a set of cogs which can ually be changed to your liking. The size of each cog is measured by the number of teeth it has, and these teeth are specially designed to work with a chain. Your chain is made up of individual links, with one link in particular being possible to unfasten easily. This is called a master link. \r
\r
The chain can be shifted up and down the cassette with a derailleur, which is attached to the bike via a small breakable part called a derailleur hanger. If your derailleur hanger snaps or bends, you can just get a new one. On the derailleur itself is a long spring loaded piece called the cage, which keeps tension on the chain. The chain passes through the upper pulley and lower pulley, also known as the jockey and idler respectively. \r
\r
Moving down to the bottom bracket shell, youll find your crankset, with the most visible parts being the crank arms. The crank arms are attached to the spindle, which runs through a set of bearings which are inside the bottom bracket shell. The spindle and bearings collectively are known as the bottom bracket.\r
\r
The part with all the teeth is called the chainring. Some bikes have up to 3 of these. At the end of the crank arms are pedals, which can be found in many different forms. The crankset, chain, derailleur and cassette are collectively known as your drivetrain.\r
\r
On a full suspension mountain bike youll find a variety of stuff connecting the front and rear of the bike together, known as the suspension linkage. At the heart of all this is your shock. This is usually fastened to the linkage on one side, and to your top tube or down tube on the other.\r
\r
Moving up, we have the seat, or saddle. The two words are interchangeable, but some people think its pretentious to call it a saddle. Personally I dont care what you call it as long as you dont correct other people. In any case this is most definitely not a saddle post, its a seat post, and its held on to your bike with a seat post clamp, or collar. These days a lot of seat posts can be adjusted on the fly. Those are called dropper posts.\r
\r
So I just named well over 50 parts of a mountain bike, but all of these parts can be broken down into hundreds more. So, put those terms down in the comments, and if youre really bored see if you can come up with an ex count of the terms I used in this video. Also, tell me how you pronounce derailleur. Are you one of those people who say “derailleeyur?”. In any case thanks for riding with me today, Ill see you next time.

Here are 30 of the worlds weirdest car accidents ever seen! From car stuck in the side of buildings to vehicles being tossed around. \r

20. Its a wonderful day in the neighborhood\r
In Palos Verdes, California in February of 2016, a driver of a Lexus lost control of his car and hit two cars before ending his drive on the roof of someones house. Unfortunately, the roof and the car sustained damage; however, the driver suffered minor injuries. The cause of the crash was a medical condition of the driver.\r
\r
19. You must be this tall to ride\r
In London in February 2008, a double-decker bus underestimated itself when it tried to drive through a low bridge. The bus lost its top half and 15 people were hurt or suffered shock from the incident; however, no one was seriously injured. \r
\r
18. Hello from the outside\r
A driver lost control and crashed his car into an unsuspecting house in Lowestoft, Suffolk, the UK on March 24th, new. The car ended up at about 4 feet off the ground. The car got enough air to jump over a hedge and two parked cars before embedding itself into the house much to the dismay of the owner of the house. The driver suffered serious head injuries and had to be released by firefighters; however eventually recovered. The crash caused a gas leak in the house but, no one was injured in the house.\r
\r
17. Irony you heartless witch\r
On August 24th, new a truck displaying the logo of the Georgia Tech Universitys football teams then slogan, “Brace for Imp” happened to be on a truck that took the advice a little too literally. \r
\r
16. Gone too far\r
This semi truck learned a hard lesson. Not everyone is meant to fly. You tend to need hollow bones and wings or some kind of jet propeller system for that. \r
\r
15. Is this your stop?\r
Quick! If a bus gets in a car accident with no passengers, does it make a sound?\r
\r
14. Drag racing strikes again\r
With a driving competition with the word “alcohol” in it, something like this was bound to happen. The Alcohol cars are reportedly very difficult to drive and the experienced driver, Steve Harker, had a bad day. He escaped with just a collapsed lung, though.\r
\r
13. Construction fail\r
This crash doesnt appear dangerous, just depressing. With the driver and construction workers looking on in resignation, something tells me this has maybe happened more than once.\r
\r
12. “Sure. Youre closed.”\r
He just really needed a donut. Whether or not this intention is unclear but, it will make a great anecdote someday. I like to think he got his donut. Probably not from them, though.\r
\r
11. Told you I could touch the top\r
This unlikely bus crash took place in India and was probably not quite as funny as it looks.\r
\r
10. Mr. Freeze takes on automobiles\r
Meanwhile in Gotham, Mr. Freeze has run out of ice-related puns and he has chosen to take it out on everyday drivers.\r
\r
9. Does my insurance cover hell spots?\r
A portal to hell has been found by this unsuspecting driver in Kerala, India. Luckily the car did not sink all the way in or we might have an outbreak on our hands. Personally, Im going to blame the car manufurer for this.\r
\r
8. The sky is falling\r
That statistic about most US bridges not being safe might stretch over into signs because this is upsetting. Looks like cardboard isnt strong enough to hold up giant metal signs. Who knew?\r
\r
7. Surprise trust fall\r
Luckily no one was injured in this wreck except the cars. Looks like in the Thunderdome of comp cars vs trucks, trucks come out on top again.\r
\r
6. Dont call me Shirley\r
This is less a car accident and more a plane accident. “Everyone ate the fish and the autopilot deflated! Hurry, that car will break our fall.”\r
\r
5. Surprise angry lumberjack\r
This is what happens when you piss off a lumberjack. Let it be a warning to all who dare make fun of their beards and flannel.\r
\r
4. Im here for my eyeglasses prescription\r
Whether that sign is misleading or not is up for debate. Shouldnt there be an arrow or something? Whatever medicine they were picking up it must have been very important because that wall its like a ton of bricks!\r
\r
3. Hello welcome to Target\r
“Neither snow nor rain nor heat nor gloom of night” ..or wait thats the post office right? Either this was a very bad decision or Target really is committed to their customers. \r
\r
2. Gas Junkie\r
On June 2nd of new, a twitter user posted a picture of this self-explanatory car wreck. This driver just really needed that gas. No word yet if he drank the gas while staring at the other driver with dead eyes. Well just have to assume he did. \r
\r
1.Somebody Turned Off Gravity\r
This mysterious vehicular event happened in China in new. A video surfaced of two vans being violently jerked
