The correct interface between rider
and bike is a crucial foundation for developing good, or even
great, riding skills. The key
is to sort out your three contact
points: the saddle; pedals; brakes and handle bars. The set up of your saddle
and pedals primarily effect "power" while the handle bars are (obviously)
all about control.
1. Sit on it
Seat height is all about pedalling efficiency
and has nothing to do with being able
to touch the ground
while sitting in the saddle. To find the right height
- put on your party dress - err no I mean
your cycling shoes, leap on your bike, prop yourself against a handy
wall and place one heel
on the pedal
at its lowest point while keeping your pelvis square on the saddle.
Your leg should be straight. Now try back pedaling with both heels
resting
on the pedals. The whole arrangement is a bit high if your pelvis rocks
from
side to side with each stroke.
There's an allen bolt under your seat to adjust its angle. Men tend
to find a horizontal setting most comfortable, whereas women prefer to
angle the nose
down slightly.
The same bolt lets the saddle slide backwards and forwards
on its rails - the central position is about right for most people. For
techno freaks, spin
your cranks to the horizontal position and use a plumb bob to line up the
back of your knee cap with the ball of your foot.
Choose a comfortable saddle. It's
an individual thing requiring trial and hopefully not too much error. Beware
of the big softie. Shape, base material
and rail flex determine comfort - not the amount of foam on top. Women
should consider a specific women's model. There are an increasing number
on the market
- they tend to be narrower in the front, softer in the nose and wider at
the back to better suit a women's pelvis shape. Be careful it's not so
wide that
you cannot easily slide over the back of the seat for steep descents.
2. Power to the Pedals
The secret to efficient pedalling is an even cadence, pushing down on one
pedal while pulling up with the opposite one. Tightening your toe straps
helps
achieve this. The ultimate solution though is to score some clipless
pedals. You click in and out of these a bit like a ski binding. They can
be a bit
daunting to come to grips with but I reckon are worth an extra gear,
or about 10%, in pedalling power. When setting up your cleats or toe clips,
you want
the pedal spindle to be under the ball of your foot.
Cycling shoes have a
stiff sole which effectively provides a large platform to push on, allowing
you to comfortably apply plenty of power to the pedals.
They're a must if you go for clipless pedals.
Cranks come in different lengths
- the standard is 175mm. Riders with shorter legs should consider 170mm
cranks which require less flexion and extension
of your leg muscles to complete a rotation.
3. Braking
One finger braking. With modern brakes you only need to use one or at the
most two fingers to arrest the progress of your lively mount. Think of
your hands
performing two independent functions:
Controlled riding in difficult terrain
is only possible by performing these two functions independently. You'll
probably need to move
your brakes towards
the centre of the bars so your inside fingers can easily grab the brake
at the outside for maximum leverage. This can make combination brake/gear
shifters
slightly more difficult to reach but is an acceptable compromise in my
opinion.

Brake
lever angle - try them angled down at about 45° to
begin with, then jump on your bike and work the brakes - adjust them
up or down until it feels
most comfortable.
If you have smaller hands then adjust the brake levers closer
to the handle bars by tightening the bolt under the brake mechanism.
The distance
from saddle to handle bars should be comfortable, ie. not too cramped or
over stretched when riding. This distance
will be correct if you
have the right size frame. It can be adjusted with different length stems
but this does change the bike's handle. Keep within a range of 110-130mm.
Your
handle bars should be around 25-75mm lower than the top of your seat
(lower bars are better for hill climbing, higher is
better for descending and
is more comfortable for your back). Adjust handle bar height by using
a stem with a different rise (-5° to 25°) or placing spacers
under the stem. An easy option for raising the height is to use downhill
bars.
