FIT
IS EVERYTHING
The
most overlooked aspect of riding is a proper fitting bike!
Sadly, too many any people end up riding a poor fitting
bike. Regardless of what kind of bike you own or what
type of riding you do, the most important feature is that
your bicycle fits you properly. Improper bike size and
set-up can create knee, neck and back pains, making riding
uncomfortable. Conversely a proper fitting bike will make
cycling easier and more enjoyable. The best thing to do
is head for a real bike store and ask to be fitted to
your existing bike, or better yet, be correctly fitted
to a new bike. Many bike shops will adjust seat and handlebar
height and angle, we at Gord's will often take the time
to do a complete fit assesment of your most favorite bike.
While this process is designed for the more advanced riders
to improve performance, Itwill benefit anyone who rides.
Fit Basics
There is no standard for bike fit, everyone will be different!
The right fit for you will depend on your body geometry
and how aggressive you want to ride. To get the right
bike fit, you have to do 2 things:
1) Spend some time riding and testing different set ups.
Move the saddle and handle bars into a few different positions.
Then try each one with a short ride, this leads to the
second thing to do.
2) Pay attention to any aches or pains as you ride. For
example, back pain may be caused by leaning to far forward,
sore knees could be as simple as the result of a poor
saddle adjustment.
The following are some suggestions for fitting your bike
properly, which should provide you with a starting point.
If after adjusting your bike you still feel un-comfortable,
maybe you should visit us for more help.
1 - Check your frame size
The first thing is to make sure you have the right size
bike frame, stand over your bikes top tube (between the
seat and the handlebar). Rule of thumb is for road bikes,
you should have roughly 1 to 1 1/2 inches of clearance
between your crotch and the frame. For a mountain bike,
you should have 2 to 6 inches.
2 - Positioning your saddle
Everyone's saddle position will be different because of
personal preference, riding style, and body geometry.
The following three positions will greatly affect your
riding. You will need to try a few different positions
to decide which is best for you. Remember if you feel
any discomfort chances are your positioning is wrong,
try again or seek the aid of a professional bike shop
employee.
2a - Saddle Position #1 (height)
Correct saddle height will provide you with hours of enjoyable
riding. It will lower the stress on your knees and provide
the most power to your pedals. Your saddle height should
be set so your legs almost (but not quite) fully extend
at the bottom of each pedal stroke. To check for correct
leg extension, rotate your pedals to the 12 o'clock and
6 o'clock positions (while sitting on your saddle). The
bottom leg (6 o'clock position) should have a slight bend
in the knee.
To adjust your saddle height, loosen the binder bolt
(or quick-release lever) located where the seat post and
frame meet. Slide the seat post up or down in the seat
tube as needed, being careful not to raise it beyond the
"minimum insertion mark" (already etched into
its side). Straighten out the saddle and re-tighten the
binder bolt ( or quick-release lever) securely before
riding.
2b - Saddle Position #2 (tilt)
When it comes to saddle tilt some cyclists prefer a forward
tilt, or a backward tilt, and some people like their saddles
completely level. To find a tilt position that works for
you, start with the saddle completely level to the ground
(horizontal) take a few test rides, try some different
angles.
To tilt the saddle, simply loosen the binder bolt directly
under your saddle, make your adjustments and re-tighten.
2c - Saddle Position #3 (fore/aft)
The fore/aft position of your saddle can have a significant
effect on your body position while you ride. To check
this, sit on your saddle using a stationary object to
keep yourself balanced and rotate your pedals until they
are horizontal (at the 3 o'clock and 9 o'clock positions).
You will need a piece of string about 30 inches long with
a weight tied to the end (like a pencil). Now using the
foot in the 3 o'clock position place the string on the
small bony bump just below your knee cap and let it hang
straight down to the foot. With a properly positioned
saddle the pencil should line up with the axle of the
pedal. To adjust this simply loosen the seat post binder
bolt and slide your saddle forward or backward, then re-tighten
the bolt securely before riding.
3 - Positioning you handlebars
Handlebar position will effect your comfort while riding.
There are 2 positions to consider for handlebars
1.) Height - this will determine how upright you sit,
a taller handle bar will allow you to sit more upright,
for a more comfortable ride. a lower handle bar will give
you a more aggressive handling bike, good for off road
trails.
2.) Length of stem - this will determine how stretched
out your upper body will be, a longer stem will cause
you to stretch out more.
Again everyone's positioning will be different! Depending
on the type of riding you do, and your body's geometry.
To find the best height for you, start with your handlebar
about 1 inch lower than the height of your saddle. Ride
for a while with the bars in this position, and see how
your body reacts. If your lower back starts hurting and
you may want a more upright position (raise your stem
slightly).
4 - Conclusion
Now keep in mind that these are just guidelines and that
a proper fit can't be acheived over the internet. Most
of what you've read has been poached off the web and some
of it is relevant to you and some of it isn't. The very
best thing is to drop by our shop and have your people
talk to our people... And let's start from there. The
right fit is so subjective. Only you know what feels right
and doesn't, we'll just be your sherpa for that particular
adventure.
