If you are getting going on a training schedule that
includes cycling at regular intervals, or have looked out the window
and have seen the light, you will need to get that bicycle out from
under any cobwebs or out from the dark corner it may have been parked
in last year. A few moments spent examining your two-wheeled situation
will greatly enhance the quality of your riding experience and it's
fun!
The first thing you really should do once you get
the bike out from storage is to do the walk around. From a safety
perspective, this is a valuable exercise. Begin by examining your
tires. On the side of the tire (known as a sidewall) there will
be a number that tells you how much air pressure to inflate the
tires to. It is important that you keep the tires at full pressure
so that they roll well and are less inclined to pick up small road
debris, which cause flat tires. There are two types of valves that
are used. The traditional valve you see on your car tire and other
inflated equipment is what is known as a shraeder valve. This is
an easy thing to deal with as you can simply remove the cap and
place the pump on it and go. The more fancy valve that is used pretty
much on any bicycle sold in a bike shop over $450.00 is known as
a presta valve or the skinny valve. To inflate tires that are equipped
with a presta valve, it is important to remember to remove the cap
and unscrew the nipple all the way to the top. This opens the actual
valve, allowing air to be pumped in. The next thing you must have
is a presta valve adapter which screws on over the skinny valve
like the cap would; only this allows you to hook up a standard air
hose. Once you pump up your tire, remove your adapter and remember
to screw down the nipple all the way so the air doesn't bounce out.
If you don't remember to unscrew the nipple when inflating a tire
with a PV, it will drive you nuts and you might get frustrated right
out of inspirational moment! In addition to getting air in the tires,
this would be a good time to look at the condition your tires are
in. When rubber sits around for a while, a condition known as dry
rot develops. This is a chemical breakdown of the compounds in rubber
that cause the tires and tubes on your bicycle to crack and dry
out. Tires that have a lot of cracks in the treads and sidewalls
need to be replaced, as they will soon fail you. Inner tubes that
are a few years old will become porous, and they will not hold air
very long.
Now that we have our bike out and the tires are inflated,
we should take some time to look at the quick release axles. Most
decent bikes are equipped with a quick release axle on the front
wheel and usually the rear. These things should have the quick release
skewer firmly pointed upwards on the non-chain side of the bike.
Sometimes when bikes are stored away, the wheels were removed and
perhaps hastily put back on incorrectly. I don't think I need to
go any further in telling you what might happen if you are riding
a bike with a wheel that isn't secured properly! To properly use
a quick release skewer, make sure that the wheel is securely positioned
right where it should be, and properly centered in the fork of the
bike. Check to make sure that the wheel is in fact right up the
middle of the bike, thus not hitting the brakes as it passes by.
The lever on the quick release device rotates up and down. Many
people twirl the lever around in a circle to secure it to the bike,
but it goes 90 degrees up and down. The lever on the front should
match the one on the rear, pointing upward on the non-chain side.
It is important to know that when you go to put the quick release
lever into it's secure position; it will begin to grab at the point
where it is parallel to the ground. As you push up on the lever
it will lock the wheel onto the bike. While most of the time you
will be concerned with the front wheel, it is just as important
to do that same for the rear. If you need to adjust the tension
on the quick release lever so that it is grabbing about halfway
through the upward turn, tightening or loosening the cone shaped
nut on the other side can do this. If you have an older bike with
a worn out quick release lever, replace the skewers! Skewers range
anywhere from $10 a piece and up and can be fun and fancy if you
like!
Is your seat properly adjusted? You want to have good
leg extension as you pedal to get the most from your pedal strokes.
A slight bend at the knee is good, you don't want to hyper extend
your self. It is important to note that if you don't like the looks
of that seat on your bike, there are many comfortable options available
for around $30.00 If you even think your going to be uncomfortable,
check out a nice comfortable gel saddle. There are many styles available.
Comfort is important.

Before we get rolling out the door, let's take a moment
to look at the chain and cables of the bike. The mechanical systems
of a bicycle are mostly based on cables and springs. Cable and spring
tension determine how crisply brakes and gears respond to the controls.
If cables become frayed at the ends, they could snap when you would
least want them to (which is never!). This is very critical with
brakes for obvious reasons. Take a moment to study your bike a little
and see if the cables aren't frayed and coming apart. Also regarding
cables, if the housing that the cables travel through is kinked
and cracked you will notice a sluggish response from your gears
and brakes. This can be replaced along with the inner wire. Dirty
and rusty cables will slow you down. The chain of your bicycle might
need a small amount of Teflon based lubricant. If you have been
out and in the elements, sometimes the weather can knock out the
lube from the chain and it's rollers. You will know when you need
a little lube by the constant squeak of the dry chain, which is
being worn out faster with each pedal stroke. To lube the chain,
drip or spray some Teflon based lube (I prefer Tri- Flow) into the
center of the chain so that it drips into the rollers that are between
the links. Wipe off any excess with a paper towel or rag as you
let it pass through your hand. Be careful not to use too much too
often as it will gunk things up.
Now were rolling! A few moments spent on some of these
basics will enhance your cycling experience and you might discover
how much fun bikes can be!
Have a happy and heartfelt ride!
