Some tech savvy cyclist came up with a fixed gear calculator that can be downloaded as an iPhone or iPod Touch application via the iPhone App Store. The fixed gear calculator is capable of calculating gear ratios, gain ratios, gear inches, and development – to list a few. The calculator is only offered in English at the moment and requires at least 1MB of disk space on an iPhone running 2.0 software or an iPod Touch. Check out more details here.

I guess I’ll just throw my lot in with all the spammers, but I have just recently released Fixed, which is a FREE iPhone app that displays thousands of rad pictures of fixies. You should download and enjoy more fixie porn than you can shake a stick at! http://itunes.com/apps/Fixed
