You should start by finding a reliable pressure gauge
or a pump with a pressure gauge. Then, use this same
gauge or pump anytime you are making adjustments. A
gauge can be very inaccurate, so if you switch around
it you can make things much more difficult.
You should start with a higher pressure of around 40 -
50 psi. If you have a tubeless system, you should
start lower, 30 - 40 psi. The more you weigh, the
higher pressure you should start with. Try this
pressure for a while and get a feel for how the tires
take corners and loose dirt.
Drop the pressure by 5 psi in each tire and get a feel
for how this new setup rides and how it compares to your
previous setting. You should notice some improvement
in stability, and if you don't, drop the pressure by
another 5 psi.
You want to find the lowest pressure you can ride with
without sacrificing pinch flat resistance. A pinch flat
occurs when your tire rolls over an object then compresses
to the point where the tire and the tube get pinched
between the object and the rim on the wheel.
With tubeless tire systems, you can run much lower air
pressure, as you don't have to worry about getting pinch
flats. If you start to dent your rims, burp air out
along the bead, or feel the tire roll under the rim
during hard cornering, you've taken the pressure much
too low.
Once you've found a comfortable setting for your tire
pressure, learn what your tire feels like when you
squeeze it with your hands. Once you know what your
tires feel like you can always get the right air
pressure - with any pump.

Setting Your Tire Pressure
Riding your mountain bike with the appropriate
amount of tire pressure can make a huge difference
in how much control you have over your bike.
Setting your tire pressure too high will make for
poor contact with the ground and also make your
bike less controllable. Setting your tire pressure
too low will make your tires unpredictable and also
make them susceptible to pinch flats.
The appropriate amount of tire pressure in a
mountain bike will vary between rider to rider and
tire setup to tire setup. The conditions of your
trail and the type of terrain your riding will also
greatly impact what tire pressure you should be using
in your tires.
The trick here is to find out exactly what mountain
bike tire pressure works for you and your setup during
normal conditions. After doing this, you can learn
to adjust your pressure for different trails and types
of terrain as needed.

To go faster you'll need a different ratio
To go faster you'll need a different ratio. To
ride downhill at 25 MPH with a 50 RPM cadence at the
pedals, you'll need a 5.6:1 gear ratio. A bike
with a lot of gears will give you a large number
of increments between a 1:1 gear ratio and a 6.5:1
gear ratio so that you can always pedal at 50 RPM,
no matter how fast you are actually going.
On a normal 27 speed mountain bike, six of the gear
ratios are so close to each other that you can't
notice any difference between them.
With actual use, bike riders tend to choose a front
sprocket suitable for the slope they are riding on
and stick with it, although the front sprocket can
be difficult to shift under heavy load. It's much
easier to shit between the gears on the rear.
If you are cranking up a hill, it's best to choose
the smallest sprocket on the front then shift
between the nine gears available on the rear. The
more speeds you have on the back sprocket, the
bigger advantage you'll have.
All in all, gears are very important to mountain
bikes as they dictate your overall speed. Without
gears you wouldn't be able to build speed nor would
you be able to pound pedals. The gears will move
the pedals and help you build up speed.
There are all types of gears available in mountain
bikes, all of which will help you build up a lot
of momentum if you use them the right way.

How Mountain Bike Gears Work
The gears in mountain bikes just keep getting more
and more intricate. The bikes of today have as many
as 27 gear ratios. A mountain bike will use a
combination of three different sized sprockets in
front and nine in the back to produce gear ratios.
The idea behind all these gears is to allow the
rider to crank the pedals at a constant pace no
matter what kind of slope the bike is on. You can
understand this better by picturing a bike with
just a single gear. Each time you rotate the pedals
one turn, the rear wheel would rotate one turn
as well (1:1 gear ratio).
If the rear wheel is 26 inches in diameter, then
with 1:1 gearing, one full twist on the pedals
would result in the wheel covering 81.6 inches of
ground. If you are pedaling at a speed of 50 RPM,
this means that the bike can cover over 340 feet of
ground per minute. This is only 3.8 MPH, which
is the equivalence of walking speed. This is ideal
for climbing a steep hill, although bad for ground
or going downhill.

Mountain Biking Vacation
Taking a mountain biking vacation is an excellent
way to unwind and explore America. There are several
companies that offer mountain biking tours that go
through scenic routes, and they often arrange any
accomodations for travelers as well. For athletic
couples, these types of vacations offer the perfect
way to relax and enjoy some exercise together.
Each and every region in the United States has some
truly awesome mountain biking trails. It's not just
the major mountain ranges that offer these trails, as
any hilly, scenic, rough trail can provide riders with
the adventure they seek. Some of the best areas to
mountain bike ride in the United States are the Pacific
Northwest, Southwest, and Southeast states such as
North Carolina.
Even though the entire American West area is great for a
mountain biking vacation, the Southwest area is rapidly
becoming a popular area for the sport as well. In the
Southwest, some of the best trails include Pinery
Canyon Road in Arizona, South Boundary Trail in New
Mexico, and Flume Trail in Nevada.

How To Lube Your Mountain Bike
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.

Keep your speed under control
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.
Knowing 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. Always think about what you are
doing and go with your instincts.
