Road bikes: Aero vs. Endurance – How to choose?


Hey folks!! This is peter from bikes and
life. Now today we’re not going to review a
particular bike, we’re actually going to take a look at the differences between
two different frame geometries, to give you the information that you can use to
buy your next bike. So on my right we have an aero road bike the
quintessential aero road bike from giant that is the propel and on my left we
have the BMC GF 01 which is an endurance road bike. These two bikes
represent opposite ends of the road by geometry spectrum. so the propel over
here is very aggressive, lightweight designed to be as fast as possible. you know with a lot of compromise for
comfort and relaxation. On the left the BMC grand fondo the endurance geometry
and this bike is setting in a more relaxed position it’s all about comfort, compliance all
day riding and so on a bike like that you can still go really really fast but
you’re going to have to work a little bit harder because you’re buying more
comfort than you’re buying speed so now let’s take an in-depth look at
the differences between your aero road bike and your endurance road bike .The
primary difference between any aero bike versus an endurance bike is going
to be in geometry which is the same as saying body position gearing which means
how the bike is set up? According to like whether they expect
you to go super fast or they expect you to kind of be a more of a moderate pace and then lastly it’s going to be in
compliance now let’s take a look at the two different bikes and how they compare
each of these points. so firstly geometry and body position on
the propel you can see the head tube is shorter compared to the head tube on the
BMC and that’s because this is going to bring your handlebar position lower
which brings your shoulders forward and your head down. so that you make a
smaller shape to the wind when viewed from the front. so that’s all about aerodynamics if
you’re going to be sitting in a more upright position you have much more of a shape that’s
going to be creating wind resistance and you have a less streamlines kind of you
know shape in your body but then again less weight on your hands you know a little bit less strain on
your shoulders and your lower back and you don’t have to tilt your neck up as
much to still be able to see compared to when you’re in the aero position you know you’re definitely getting more
over the bike your neck is like this and you’re kind of trying to combine the
whole torso and head of your body into one streamline kind of bullet shake aside from body position another thing
that they do on aero vs endurance bikes is they change the way that the
handling is set up on aero road bike because this is more of a race machine you’re going to have a more aggressive
quick steering so what they do is they’ll actually change the angle of the
fork, the rake of it and they’ll bring it back a little bit to have a steeper
fork break angle. what that does is it’s just allowing you
to turn more quickly so you can adapt to race situations. In a faster way on an endurance
road bike you’ll have more of a rake to the port which is called a slackened
head tube angle which is allowing you to have a broader turning radius for a more
stable kind of comfortable at speed feeling and start to say that you
couldn’t be comfortable in an aero bike but it does require a little bit more
fine control compared to the forgiving handling of an endurance bike one of the
more subtle differences between an aero bike versus an endurance bike is the
gearing on an aero bike you tend to have a much bigger chain ring this is a 53-39 combination in the front
for the chain ring and a 53 tooth gear is massive. it’s the kind of thing that you’d ride
if your pro racer if you’re well if you’re racing in general because it
allows you to achieve a faster top speed without spinning out on your feet on
endurance like you have what’s called a compact road group set and that’s going
to be like a 52-34 in the chain ring in the front so that difference of three teeth
alone on the top here is a is an incredible difference to lower your gear
range, overall making it easier to climb Hills you know spin your feet faster not
have to push those heavy heart part gears. Last but definitely not least is the
compliance of the bike and that’s the feeling that you get when you’re riding
it is it harsh but fast or is it comfortable and relax right so when you’re designing a bike you kind
of have to trade off between these two different avenues and more and more
technology is coming along where you can get the compliance with the stiffness
that leads to performance but ultimately these two bikes greatly differ in their
compliance the aero road like of the propel has a
much more rigid frame which is leading to a better transfer of power from your
leg power and your arm power your whole body transferring the power through the drive
train and into the wheels that makes you go fast – everything here is tuned to use every
ounce of your muscle power as effectively as possible and there are
you know a significant number of compromises to your comfort just like
the aero position is designed to minimize the impact of wind has on you
on an endurance road bike everything is tuned to give you a balance between
performance and comfort so you have a longer seat tube that’s
also narrower so it can flex back and forth to absorb that shock you have
kinks in the frame here you have kinks in the frame here and shape changes and
junctions and pinks and even pivot points are becoming more and more part
of Road bike designs in order to tune in that compliance now there are there are different ways
with the tubes are shaped in order to maintain the stiffness and the
performance that you get but i can tell you this like is the
super comfortable all day any terrain rider this bike is the racer super fast
riding descending aggressive bike and so they both have their different qualities
and so that’s really what it comes down to how to you feel when you’re riding your bike what
are the things you’re trying to accomplish and everybody’s my store we
have in-house bit technicians that can take you through the whole process of
adjusting every little part from your seat height to your stem length the bar you may choose and those micro
adjustments smaller they maybe can make the world of difference that changes you
from you know I got the bike and I’m not so
comfortable – oh my god despite is incredible so please come by our Bikes and Life store to
learn about the different bikes we offer get fit talk to a specialist and if you
want to learn more about the giant propel we actually just published a video
