Chainvetica Apr 27, 2010

Here’s yet another gear-calculating app for the iPhone. Chainvetica is exactly what you’d expect, a gear-inch-mph calculating app in Helvetica. Simple and sweet. From the Apple Store’s description:

Chainvetica does the math your PBR addled brain cannot. Given the tooth count of your chainring and cog, it calculates gear inches — an ancient formula designed to sum up just how hard it’s going to be turn over the cranks on your fixed gear. The more inches you’re running, the harder it is to push. Use it to pick your cog. Use it to quantify the power of your massive quads.

As an added bonus, Chainvetica also calculates your speed at a cadence of 90 rpm. Your skinny jeans will make 90 rpm exactly “as fast as you can pedal” so basically, this app also calculates your ride’s top speed without all the bourgeois cables and stuff.

All this functionality presented on a bed of orange and Helvetica. Good stuff.

Check it out right here.

    Some of us real-life cyclists hit 220+ rpms pretty routinely…..
