Measure for Success – Mac Mondays #2

SizeMyBikeSizeMyBike is a simple iPhone app to help new and existing riders properly fit a bike.  Users input six body measurements (height, inseam, sternum, arm length, foot length, and shoulder width) and SizeMyBike will compute the optimal geometry of a road bike or a mountain bike. The maker of the app says that the results will help riders increase performance, improve comfort and prevent pains and injuries.  Additionally, users will be able to compute the right frame size, stem length, and crank length, as well as optimize saddle height, saddle setback and stem length.

Obtaining the six body measurements is a two person job as I found it difficult to get accurate readings by myself.  The “About” page, in the app, gives useful hints and diagrams to help achieve proper measurements.  All measurements must  be entered in millimeters (which could be a problem for riders that use Imperial units as their standard form of measurement).

Enter your measurements

After all measurements are entered, press the “Run” button and results are calculated for the rider’s optimal road and mountain bike (results are displayed in millimeters).  The results (in image form) can be emailed for the rider’s records or sent to a bike shop to help set up a bike.  The “About” page also includes tips about analyzing the results and how to apply them to the bike.  Finally, the “Home” page includes a link to the SizeMyBike website, where more detailed information is provided to help apply the results.

Road Bike Results Mountain Bike Results

Entering the measurements is easy and straight forward; but, the results displayed are difficult to interpret as the app doesn’t clearly state what frame size a rider should buy.  If you already have the proper size frame for you, the results displayed will help you tweak your bike to make your ride more comfortable and help improve performance.  One feature that is missing is the ability to save your results inside the application.  This would be useful if you were helping other riders fit their bikes and would like to refer to the data at future points in time.  If you follow SizeMyBike on twitter, I’ve noticed that the developers occasionally give general technical advice to further improve your bike fit.

At $4.99 in the iTunes App Store, SizeMyBike is overpriced for the features offered but as they say on their website: “professional bike fitting service costs about $150.”

Enjoy Your Ride

    The guy which really does more than he or she is paid for will certainly in the near future be paid for more than he does

    That does look like a cool app but I don’t have a smart phone. :(

    Eventually, I may joint the rest of the country and get one. LOL!

    I know I’m biased, but this really is a fantastic post, Myron. I really found it interesting and helpful.

    Great job.

Sugar Alternatives for Energy and Hydration

Question: I am using the homebrew sugar formulations (sometimes added to green tea).  I am also trying to wean myself off 1/2 dose adrenalean “lip tonic delivery system” (biorhythm brand- caffeine, hoodia g, synephrine, yohimbe) capsule for energy.

My question is other than juice, can you suggest modifications in lieu of table sugar for energy and hydration.

Answer:

Both raw/organic honey or agave can work great in the homebrew (substitute in the same quantities for the sugar, or to taste), but you do have to shake well in order to make sure they don’t settle out.  Have you tried either of these?  Also, make sure to use at least the minimum amount of salt recommended in the homebrew as the temps rise, you need the sodium replacement if you’re sweating.
