Caleb Ewan's Sprint Position - Revealed through Kinesiology

Measure Saddle Tilt with The Leveler App Angle Finder

Instead of measuring saddle angle the old school way using a plumb line, download the Leveler App to make your life a lot easier.  It's simple to use, free and seems to be just as accurate as a $40 dedicated angle finder tool.

If you go to the Android Market aka. Google Play Store, search "angle finder" and download the Leveler app created by chkuentz.  In order to use the free version of this app, it will require you to download Adobe Air.  If this is a deal breaker, you can download Leveler Pro for $0.99 and avoid downloading Adobe Air.  It's still a lot less expensive than driving to and buying an angle finder at your local hardware store!

Ok, so it's not exactly a free app if accuracy is extremely important, which in this case it is.  Before using the app, you'll need to calibrate the phone on a level surface- the only way to be sure that you're calibrating it on a level surface is to use a bubble level.  If you don't have one, you'll need to buy one.. but most likely, you already have one sitting in your garage or tool box.  You'll notice that even on a counter top which appeared to be level, I needed to put two sheets of paper under the left side to level it out.  I could have probably used more.

After you've calibrated the phone, you can go ahead and use it to check the position of your saddle!  If you have a saddle with a varying slope like the Selle SMP Evolution, try to find the flattest part of the saddle to get the most accurate read out.  The key is to be able to produce repeatably accurate measurements.  Take note of where you placed the phone and measure the angle at least three times.  Most importantly, write down your measurements (with the date and some subjective notes about how the saddle position felt) so that when you decide to experiment with different angles, you remember where you left off.

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…
