Bicycle Gear Calculator

Cost: $4.99

Ever been out on a nice biking trip, say UC Santa Cruz to the Capitola Mall, and then suddenly your supposedly dependable tire pops? This horrible situation can easily be avoided by using the Bicycle Gear Calculator iPhone application, which can use a unique Skid Patch Analyzer that takes into account the size of the tires to suggest the optimal gearing for the bike that will maximize tire longevity.

Compatible with almost any type of bicycle, this app is a must-have for all bike lovers regardless of the different biking styles. However, you don’t have to be an expert to truly make use of this app. The layout is very user-friendly and the units can switch between metric and imperial to make all data as easy to read and understandable as possible.

It is even possible to build your dream bike by entering the “perfect” bike dimensions on the app, which will then provide you with the realistic and affordable chain ring, sprocket and other accessories needed in order to get as close as possible to this dream bike.
