Great app for the begginers
Having both my kids starting to ride / race BMX I have found this app to be in invaluable tool. Not only is it easy to use it has save me a lot of $$$$$ in experimenting and costly purchases trying to find the optimal gearing configuration for my two kids. Keep up the great work with this app and Thank you.
