Description
This app is the free version of the "Optimum Crank Length". This app will work similarly to the full version but the results will be zero! Use it to getting in touch with the app before buying the full version.The OCL full version will allow you to calculate the optimum crank length (OCL) for your bicycle according to your body anatomy. The calcs will take in account the knee angle when pedal is at the bottom and at the top, to help protect your knees from injuries.
The OCL full version will also give you the "Seatpost Length" and "Maximum Frame Size" for your new crank length. If your bicycle is a road, mountain, trekking, cross, single speed, city, recumbent or even a trike or a velomobile, the OCL is still valid because it only depends on your body anatomy plus the pedal and shoe heights.
Its also included a "Take Care" results section to protect your hamstrings from overstretch. The app will give you two scenarios, where the first one is the "Initial Setup" and the second is the "Final Setup". The idea behind this calc is to protect the legs from overstretch but at the same time to protect the knee from bending too much. The cyclist should set the "Initial Setup" and increase the seatpost length with time by small amounts until the "Final Setup" value is reached.
To find out your OCL, 8 parameters are necessary:
(1) Total Height with Shoes
(2) Total Height
(3) Seated Height
(4) Upper Legs Width (or HJCR Height)
(5) Knee Height
(6) Ankle Knuckle Height
(7) Ankle Knuckle to Ball Foot (or to Axis Pedal Center)
(8) Pedal Height (Flat or other type )
For the "Maximum Frame Size" and "SeatPost Length", 3 parameters are necessary:
(9) Saddle Minimum Height
(10) Saddle Position (back or fore)
(11) Seat Post Angle (0 to 90 degrees)
You can use this info to find your Optimum Crank Length because everyone's anatomy is different and using a standard crank length (170/175 mm) might not be the best option for you!
The default angle for maximum leg extension is 155 degrees, for minimum is 70 degrees and for ankle rotation 20 degrees. In the "Settings" you will be able to change those values according to your preferences.
You'll be able to save your own parameters, your friends or family, and edit or calculate it later on.
The parameters can be in mm (SI) or feet and inches (imperial) and must be defined in the "Settings"
Protect your knees and enjoy cycling more!

Questions & Answers
Q: What is an APK File?
A: Just like Windows (PC) systems use an .exe file for installing software, Android does the same. An APK file is the file format used for installing software on the Android operating system.
Q: If I install an APK from this website, will I be able to update the app from the Play Store?
A: Yes, absolutely. The Play Store installs APKs it downloads from Google's servers, and sideloading from a site like ApkClean.net goes through a very similar process, except you're the one performing the downloading and initiating the installation (sideloading).
As soon as the Play Store finds a version of the app newer than the one you've sideloaded, it will commence an update.
Q: Why ApkClean.net can guarantee APK 100% safe?
A: Whenever someone wants to download an APK file from ApkClean.net, we'll check the corresponding APK file on Google Play and allow user download it directly (of course, we'll cache it on our server). If the APK file does not exist on Google Play, we'll search it in our cache.
Q: What are Android App permissions?
A: Apps require access to certain systems within your device. When you install an application, you are notified of all of the permissions required to run that application.
Don't hesitate to contact us if you have any questions or concerns.
