Quick And Easy Tips To Improving Your Shifting and Extending The Life Of Your Drivetrain
It is extremely important to learn how to use all of the equipment on
your bike so that you can use it properly and get the longest life out
of your investment. The Drivetrain and shifting mechanisms are no
exception.
An important rule to remember is to reduce your applied pressure on
the pedals during shifts. As drivetrains have seen many improvements
over the years, and have been designed to shift no matter how much
pressure is put on the pedals. However, if you ease up on the pressure
just a bit, the shifts will be smoother and your chain, cogs and
chainrings will last longer.
Here are some more tips to help keep your drivetrain in great working order:
Keeping Your Drivetrain Clean:
Before
we even get into proper shifting, it is important to make sure you keep
your drivetrain clean and tuned up to extend the life of your
drivetrain. We have chain cleaners for sale in the shop that can help
get your chain clean and keep it that way.
Every six months or so, inspect your chain and measure to see if it has been stretching.
Pick a chain pin on the top side and measure to any pin 12 inches away.
Links are exactly one-inch long, so you should be able to measure
exactly 12 inches between two pins. If the measurement is 12 1/8 inch or
longer, it's time to replace the chain.
(Check Your Cogs too!)
Remember: cogs wear out at
about the same rate as the chain. If you put on a new chain, you will
eventually run into skipping cogs - which is at best annoying and at
worst dangerous!
Remember to keep the front rings and
rear cogs clean. Stay on the lookout for a post about how to clean your
chain and drivetrain!
On The Road Tips:
Shift Before Hills:
Even
though the hardest place to put less pressure on your pedals is when
you are struggling to get up a steep hill. Try changing gears before the
steep part of the hill so you can make the shift with out stressing the
chain and pedals.
Front Shifts:
Remember
when you are shifting the front derailleur that the chainrings are
significantly different in size! This means your derailleur has to work
hard to move the chain from one to the other. If you can add some
finesse to this shift, you are much more likely to get a clean, smooth
shift. And, you'll eliminate problems associated with high pressure
shifts such as having the chain come off.
There are
three or four set spots (shift ramps/shift gates) on the chainrings to
make it shift. The chain (while moving forward) needs to contact these
ramps to be pulled up onto or down over the chainring. It is very
important to hold the shift until the chain comes into contact with a
shift ramp. When the chain is under load (meaning there is force on the
pedals) this is the ony spot where the chain will shift. Ideally
shifting should be done with little load on the chain. When the chain is
under load the derailleur will just flex and laugh at you instead of
making the shift happen. When there is no load on the chain the
derailleur will be able to move it.
Getting Your Chain BACK On:
Usually, you can shift
the chain right back on the chainring if it falls off. This is usually
impossible when climbing a hill, as you will lose momentum and have to
stop. However, any time you are riding and you can coast for a few
seconds, you can almost always get the chain back on by gently pedaling
and shifting the front derailleur to move the chain toward the ring.
(When a chain comes off repeatedly, something is wrong and you should have us take a look at the front derailleur adjustment.)
