Description

Once a guy, an addicted to fixed-gear bicycles, decided to create an application worth a community. That's how the Chainring was born.

Chainring helps you quickly calculate all necessary characteristics of your fixed-gear or single speed bikes like a ratio, a number of skid patches, development, gear inches, and a recommended number of chain links.

Gear Ratio.
The ratio of chainring teeth to rear sprocket teeth means how many times your rear wheel turns with each revolution of pedals.

Skid Patches.
Value predicts how many spots (skid patches) will wear on a rear tire while a rider brakes with one foot or both feet (ambidextrous skidder).

Development.
Development is a distance that a bicycle travels with every revolution of pedals.

Gear Inches.
Values typically range from 20 (very low gearing) via 70 (medium gearing) to 125 (very high gearing). Low gearing is for going up hills, and high gearing is for going fast.

Chain Links.
Value shows the recommended number of chain links for a regular chainstay length of the track frame.

All graphics in the app are carefully drawn and animated with love to details. The prototype of the design was my bike, which I built on my own with components of Cinelli, Campagnolo, and a bit of Dura-Ace.

You're always welcome to contact me and share your ideas. I'll appreciate that.

A must have!!

Really helpful tool to work out how to get the best from your bike. If your a climber or speeder or jumper on your bike then you need this app! Helps you work out the best gearings you need for the job, depending on your preferences.
