when it comes to buying a new bike it's
absolutely paramount that you pick the
right size there are loads different
adjustments you can make to a bike like
the stem the saddle even the seat post
or the crank length but every different
adaptation you make your bike will
affect webforms and the way it feels
ultimately if you're buying a too small
bike or even a too big bike it's never
going to feel quite right so in this
video we're going to help you choose the
perfect bite size for you
[Music]
before we start let me explain sizing
cuz it's not quite as simple as just
basing the bike around how tall you are
most manufacturers will label their bike
in sizes small medium or large
etc but others will also label them with
a number these generally range from 48
to 62 and that corresponds to a
measurement in centimeters from the
bottom bracket which is down here to the
top of the top tube there is however
nothing consistent about the way
manufacturers measure their bikes just
because you've always had a 54 from one
brand doesn't mean that a 54 from
another brand will fit you the effective
seat tube length is just one of three
really important ways of measuring your
next bike the other two ways of
measuring your bike are known as reach
and stack and these are internationally
regarded standards the reach refers to a
centre line from the bottom bracket
measured to the center line of the head
tube and your stack refers to a very
similar measurement but then includes
the height of the bike as well it might
sign slightly complicated but hopefully
the graphic on your screen will help
it's kind of like buying a pair of
trousers trousers come with the waist
size but they also come with a leg
length and much like buying trousers you
will have to try on several pairs or
ride several different bikes to find the
perfect fit for you before we get onto
that though let's get one easy but
fundamental point under our belts first
now that is what is our satellite and
how can we find it now a really easy way
is to find a wall like this get onto a
blank placing both hands on the
handlebars place one pedal all the way
down six o'clock now put your heel on
the pedal now you should find your legs
straight then when you go to clip in and
put it back into normal position you
find your leg is slightly bent really
easy but really effective way of finding
the right cell height for you
finally you're correct satellite is
relatively easy and that's because
you've got plenty of scope for
adjustment when it comes to setting your
reach though you're much more restricted
in the adjustments that you can make
even though it is potentially more
important to your comfort on the bike
now the reach of different bikes will
vary within a manufacturer but also from
brand to brand and this depends on the
type of riding the bike is designed for
but also the size of the bike you're
riding racing bikes like the ones you'll
see at the Tour de France is generally
really long and really low whereas a
gravel bike will be a little bit shorter
and higher the numbers that refer to how
the bike will be are known as stack and
reach if you remember those from earlier
if you're new to cycling you're
relatively more relaxed about your
riding or you're a little bit less
flexible you'll probably favor something
that's shorter and higher whereas if
you're into racing you'll probably favor
something that's longer and lower for
example of different types of geometry
Canyon put their three bikes in two
different categories
Pro pro sport and sport geometry so how
will you decide on where your bars need
to go or this is going to depend on a
few things if you have long arms a long
back and you're very flexible you'll
probably be able to get yourself into a
longer lower position if you're less
flexible or you have a shorter back and
arms then the opposite is of course true
as well and then finally the type of
riding that you do is going to play a
factor as well generally speaking though
with your saddle in the correct position
the relationship from your shoulder to
hip angle should be 40 to 45 degrees to
horizontal underneath your wheels with
your arms then protruding at 80 to 90
degrees down to the bars if you do need
to adjust the height of your bars this
is relatively quick and easy to do so by
adjusting the spaces whipping them out
and putting them beneath to raise your
bars or vice versa to lower them but if
you do need to adjust the reach this is
gonna be a little trickier you'll
probably need to buy a new stem or in my
case you'd need to swap the entire
handlebar set up however if you do need
to adjust your stem by more than two or
three centimeters you probably should
have a different size frame and once you
can move your saddle fore and aft by a
few centimeters this should never be
done to affect your reach your saddle
should be dictated only by your legs so
put it in the correct position leave
that where it is
[Applause]
[Music]
so you found the bike you absolutely
love but you're kind of in between sizes
maybe it's 54 or 56 a medium or a large
now the difference between both of these
bikes is the stack and the reach the
reach being this and the stack being
here if you're a larger Rider you're
gonna have a larger see post meaning you
need the handlebars that a little bit
higher hence the stack but if you want a
kind of more racier style and more race
you're feeling bike then most rides go
for a smaller bike and adding a longer
stem but if you want a kind of more
stable and more upright position on the
bike then go for the larger bike with
that higher stack ultimately you can
pick a frame size on your height and
your saddle height alone but you really
need to ask them what kind of frame you
want do you want long and low or do you
want upright if you did enjoy this video
