Caleb Ewan's Sprint Position - Revealed through Kinesiology

Planet Bike Protege 9.0 Bike Computer Review

I was very happy with the $40 I spent on the Planet Bike Protege 9.0 bike computer from  This was the first bike computer I have ever used and since day one, this computer has been very reliable even in extreme conditions from below zero wintry conditions to 100+ degree summer temperatures.  Just like any other computer, as long as the computer is installed correctly, this computer can be a five star product.  Mine has consistently measured all of the basic information that it was designed to monitor such as speed, average speed, maximum speed, ride time, distance, time of day, total distance (odometer) and temperature.

A computer can have a lot of nice features on paper, but if it doesn't perform well in actual riding conditions, that's money wasted.  Since I was only willing to spend around $40, I chose to get a wired computer to avoid the likely problem of a poor quality wireless connection which I have heard was a big problem with budget wireless computers.  Rain, snow or mud (happened on accident), this computer has never failed to work, so I'm happy!

If you don't want to include the data from the warm up or
cool down, you'll find out that there's no pause button.  Just
unclip the computer off the electrode to cut off the
connection.  Now it has a pause function!
With over two years of use about 4-5 days per week, the Planet Bike Protoge 9.0 has excellent "battery economy."  The Protoge 9.0 does a good job at saving energy by using their trademarked "MacroMonitor" display similar to the display on a calculator.  In terms of visibility, the display was especially visible in overcast and sunny conditions- see the picture to the right.

The feature I liked the most was the convenient design they integrated to make navigating the menus so easy that you would never need to take a hand off the handlebar (unless you're on the drops).  With both hands on the hoods, all I had to do was take a thumb out and press the computer forward (towards the tires) to switch screens.

Another feature that I tend to take advantage of a lot was the average speed indicator.  Whenever my current speed would fall above or below the average speed, an arrow will point up or down, respectively.  This helps when the display is set to a screen that doesn't show average speed.

The lack of a back light makes the display almost impossible to read.  I say "almost" because with a small helmet or visor light, the lack of a back light really isn't a problem at all.  Aside from the extra cost of buying a visor light, there really isn't that much more to improve that wouldn't up the cost of this computer.

I have to admit that it does sort of suck not having visual feedback for cadence.  To get around not having cadence, I've been using a metronome app from my phone to estimate cadence, although it would help a lot more to have real-time feedback.


All cycling computers must pass this test!  It would be a real disappointed if a cycling computer managed to fail a simple feature like this.  Since the Planet Bike Protoge 9.0 had a temperature feature, I tested it out.  As shown in the picture to the left, Planet Bike passed!  Click on the image to enlarge it- I had really bad lighting when I took the picture.

Sensor attached to rear side
of the fork.
Keep the magnet as close as possible
to the sensor for better readouts
With a carbon fork, installing the Planet Bike Protoge 9.0 is still possible to do.  Rather than using a less flexible zip tie to hold the sensor against the fork, use electrical tape and tightly wrap the sensor.  Electrical tape was designed to withstand heat, water and cold, so there's nothing to worry with regards to durability.  Be sure to place the sensor near the back of the fork- this is extremely important.  Placing the sensor in the back will prevent the magnet from smashing into the sensor if you happen to make a mistake with installation.  Notice how close the magnet must be to the sensor.  This is pretty much standard protocol with any cycling computer.

Kinesiological Approach To Bike Fit: Cleat Position

CLEAT POSITION:  There are four types of adjustments which can be made to a cleat.
Fore/ Aft:  FORE:  Positioning the cleat forward allows the ankle to move more freely, allowing for a smoother pedal stroke.  The trade-off is that this requires more ankle stability, calf strength and puts the rider at risk of developing quad dominance.AFT:  This position limits ankle motion.  This provides added stability to the ankle, allowing the calves to rest, but makes the rider prone to bouncy pedal strokes.  When switching from a forward cleat position to a rearward position, a lower saddle position is needed to compensate for decreased plantarflexion.Lateral/ Medial:  The goal is to spread weight evenly across the foot side-to-side.LATERAL:  Shifts weight towards the outside of the foot (small toe side).MEDIAL:  Shifts more weight onto the medial side of the foot (big toe side).  Limits the maximum amount of external rotation available before the heel strikes the crank arm.Rotation:EXTERNAL:  S…

How To Hold an Aero Position

There are climbs and then there are winds.  For many cyclists, riding into a strong wind can be more difficult than climbing, mostly because cyclists are required to reach a low aerodynamic position which can be uncomfortable, difficult or painful to hold.  Cyclists must demonstrate adequatehamstringandlower backflexibility to hold an aero position comfortably.  The flexibility needed to ride well in the wind can take time to develop, but with enough dedication and experience, anyone can become proficient at holding an aero position safely.  Here are some steps you can take to make holding an aero posture as comfortable as being on the hoods:

The worst thing a rider could do is force a low aero position and hope for the best.  With low back pain being one of the most frequent complaints among pros and recreational cyclist alike, the chances of long term pain- or injury-free riding are slim.  Develop the flexibility first, then shoot for the next lowest position yo…

Eagle Creek Park Cycling Grand Prix v2.0 - FIRST PLACE & FIRST PODIUM FINISH!

I can't even begin to describe how awesome it felt to have two dreams come true at once!  I always wondered what it would be like to be on the podium, but I never thought I had a chance at first place!

THE COURSE Below is a map of the course highlighted in blue.  It ran counterclockwise.  There were a few corners that stuck out to me.
Bottom right (corner #1):  This wasn't a very sharp corner, but the trees and brush made it difficult to see around it, so the group had a tendency to slow down and merge into a single line here.
Top right (corner #2):  This corner was very sharp, so oftentimes the group would merge into one or two pacelines, especially at higher speeds.
Top left (corner #3):  The inside half of this corner was covered by loose asphalt, so it wasn't an ideal or safe place to pass.  Pretty much everyone had to take a very awkward, wide line.  We could only fit about three abreast in this corner.
Bottom left (corner #4):  This was a very fast corner that led straigh…
