Wheel truing is actually something that is very easy to do.  Even if you have no experience with mountain biking or truing a wheel, it doesn’t take a rocket scientist to accomplish it.

The first thing to do is make sure that none of your spokes are loose.  To check, grab each spoke in turn and try to shake it back and forth.  If the spoke wobbles, or makes pinging and grating noises, it’s loose.  If it’s loose, add tension to the spoke by turning the spokey anti-clockwise with your finger and thumb pressure.

Keep turning and shaking until the noise is gone and the spoke doesn’t wobble or move.  Move on to the next spoke until you’ve gone all the way around the wheel and checked them all.

Now, it’s time to see just how true the wheel actually is.  Turn your bike upside down then spin the wheel to see where it comes closest to rubbing on the brake.

You may need to rotate the wheel backwards then forwards to locate the middle of the bulge on the wheel.  Tighten the spokes which run on to the other side of the rim.  If those spokes are already tight, you’ll need to loosen a few of the spokes which run to the bulge side of the hub.

Truing a wheel is easier than you may think, although it can be a little tough with some wheels.  If you need to loosen spokes, be very careful that you don’t break them.  They can be very tough to loosen on older mountain bikes.

In mountain biking and even BMX riding, the bunny hop is a bike trick that involved the rider lifting the bike up and over an obstacle while remaining in motion on the bike.  Experienced bikers can lift their bikes in excess of a meter or one and a half feet.  The world record for the bunny hop stands at 4 feet.

The bunny hop is executed by approaching an obstacle with speed, lifting the front of the bike then leveling the pedals.  If the bike has full or front suspension, pre-load the shocks by pressing down on the bike just before you reach the obstacle.

Once the shocks have been pre-loaded, the rider will spring upwards, pulling up with the hands and feet at the same time.  Toe straps or clipless pedals help with this, although if plain platform pedals are used, it’s still possible.  As the biker lifts, the hands will roll through twisting the throttle.  After the object is cleared, push down on the bike then absorb the impact with the arms and the legs.

It’s often times a misconception that a bunny hop without toe clips is achieved by rotating forward on the handlebars.  Lifting up on a mountain bike while standing next to it is quite difficult to hold on to the handle bars.

The bunny hop is very popular with mountain biking, as experienced riders can make it look a lot easier than it actually is.  New mountain bikers should practice a lot before they actually attempt the hop, as doing it on a bigger obstacle can easily be quite dangerous.

With proper practice, the bunny hop can be achieved, even for beginners.  All you have to do is give it some time and effort, and you’ll be pulling off the bunny hop just like the pro’s do it.

If you take part in mountain biking, especially the extreme kind, then it is inevitable at some point that you will have a crash. You can see mountain bike crashes on DVDs around the world, some are lucky as they have the right safety equipment, whilst others are not. Stunt crashes can be fascinating to watch, but the real life ones can be horrific and they can cause serious injury.

The potential injuries that can occur with mountain bike crashes are endless. Many bikers have been impaled on their bikes handlebars, they have broken their arm after falling off and some have even been paralyzed after a bad fall. So the injuries that you can sustain are quite severe. Crashes don’t just occur when you take part in extreme mountain biking. They can also occur when you take part in casual riding too. However obviously there is more of a risk involved with extreme downhill riding where jumps and tricks are involved.

Protecting Yourself against Crashes

The only way to truly protect yourself against a crash is to ensure that you have the correct safety equipment. You cannot always predict a crash when you are out riding on your mountain bike, but if you wear the appropriate safety equipment then you can at least protect yourself from serious injury. It doesn’t matter whether you are a beginner or an expert rider, you will have a crash at some point. So what protection should you have to keep you as safe as possible?

When you hit the ground after a fall, usually the first things to get hurt are your hands. Many people do not think to protect their hands whilst they are out riding and unfortunately that can cause problems if you do fall off the bike. The wrists ad our fingers are most sensitive to injury after a fall and it only takes a minor knock for them to get seriously injured. So wearing gloves is definitely a good idea as if you do fall off, the skin will be kept in place because of the gloves.

Essentially however the most important safety equipment you will need is a helmet. You should never go anywhere without your helmet, even if you are just going on a leisurely ride along a field! Anything can happen and the accident may not be your fault but if you fall and hit your head you could potentially suffer a serious injury. The way that helmets are designed these days makes them extremely comfortable to wear. They really can make the difference between life and death and so if there’s one piece of safety equipment you will not go without, make sure that it is the helmet.

Overall the helmet, gloves and eye protection are generally the only safety equipment you need when out cycling. You will definitely suffer from at least one crash on your bike so it is always better to be prepared for the inevitable.

2.  Brake cable – This is the cable that connects the brake lever to the brake mechanism.

3.  Brake lever – The lever on the handlebar to activate the brakes.  The left side is the front brake and the right side is the rear brake.

4.  Chain – The circular set of links that transfer power from the chain ring to the cogs.

5.  Chain ring – The toothed rings that attach to the crank to hold the chain.

6.  Crank – The lever that extends from the bottom bracket to the pedal, transferring the power to the chain rings.

7.  Derailleur – The mechanism for moving the chain from one cog to another.

8.  Down tube – The section of frame that extends downward from the stem to the bottom bracket.

9.  Front shock – The shock absorber on the front fork.

10.  Handlebar – The horizontal bar attached to the stem with handgrips on the end.

11.  Headset – The mechanism in front of the frame that connects the front fork to the stem and handlebars.

12.  Hub – The center part of the wheel that the spokes are attached to.

13.  Idler pulley – The bottom pulley of the rear derailleur that provides spring tension to keep the chain tight.

14.  Nipple – A threaded receptacle that holds the end of the spoke to the rim.

15.  Pedal – The platform to pedal on; attaches to the crank.

Knowing the names of the parts will help when you need help from a bike shop.  You will be better able to explain the problem your having and what you need to fix it or replace.

There are numerous ways that you can improve your mountain bike safety.  Many riders will tell you that wearing a helmet is the most important step to staying safe.  The second most important step is that you should always ride in control of your mountain bike.

By riding in control you’ll not only prevent crashes, but keep others on the trail safe as well.  When riding out of control you loose the ability to adjust to the terrain as you ride over it.  This can and usually does result in serious injury to yourself and others.

Follow these helpful guidelines and you’ll remain safe when riding your mountain bike.

Gear
Always make sure that you wear a helmet and other necessary safety gear for the conditions that you
plan to ride in.

Never Ride Beyond Your Control
There is never any shame in walking the areas of the trail that you don’t feel comfortable in riding and you should never let anyone else tell you that there is.

Keep Your Speed Under Control
Always make sure you keep your speed at a level where you can quickly adjust to any obstacles or change in the trail.

Know Your Trail
You should never push the limits on trails that you aren’t familiar with.  You should take trails you aren’t familiar with at slow speeds until you learn them better.

Slow Down Around Blind Corners
If you can’t see past a corner you should always slow down, as you never know who or what is around it.

Start Small Then Go Big
Work your way up to stunts or obstacles.  Practice in less difficult or dangerous situations before you move up to something more dangerous.

Playing It Smart
If you start to question what your doing, you probably shouldn’t be doing it.  Always think about what you are doing and go with your instincts.

A mountain bike is a lot of fun although it does require some maintenance.  You should always lube your bike 15 hours or so before riding, as quick jobs right before you take off normally doesn’t get everything lubed.  Some lube jobs will last for more rides, although if things get loud or shifting gets sticky, it’s time to lube.

Here is how to lube your bike:

1.  The chain
Apply a generous amount of mountain bike lube to your chain as you move the pedals around backwards.  It also helps to find a spot to steady your hand such as the frame while you move the pedals around and around.  Make sure you watch out for the cranks and chain rings as they move around.

2.  Front Deraileur
On the front defaileur, lube the pivots.  Use a spot of lube everywhere you can see movement when you move the shift lever.

3.  Rear deraileur
Just like the front deraileur, lube the pivots.

4.  Pedals
There are some types of clipless pedals that will need to have the release mechanism lubed.  You should only lube this mechanism if you have this type of pedal.

5.  Everything into motion
Pedal around, shift your gears, and bounce your bike around.  If you hear anything squeak, there’s a moving part there are it should be lubed immediately.

6.  Wipe it all clean
Once you’ve lubed everything and wiped it all around, simply wipe it all back off.  Use a rag to wipe away all the lube you used, including all the lube off the chain.  Wiping it away will leave the lube in between the parts but clean it away from everywhere it isn’t needed.  This will keep your bike from collecting dirt while you ride.

This time of year, mountain bikers love the rain.A little midsummer moisture on the dry, dusty trails of Central Oregon is a welcome sight.A thunderstorm pounded the region on Monday, so on Tuesday, I secured my mountain bike to the car and drove south through Sunriver and west to Cultus Lake.

The Olympic women’s mountain bike race has been pushed back one day to Saturday because heavy rain created unsafe and unsatisfactory course conditions.

A radically changed Olympic mountain bike course with freshly-added banking, drops and rocks is set to test the technical skills of the best women mountain bikers in the world on Friday.
