The Surly Dingle Cog is the right choice for everybody, who needs a second gear on their fixed gear bike. With the Dingle in the back and two chainrings in the front that are 2 teeth apart, you will always have two different usable gears available. Using the inner or outer chainring/cog combination you don´t have to worry if you have too much or too little chain length. That means you can get your bike ready for off- or onroad riding. Made of CNC machined, heat treated and chrome plated steel for long durability. Compatible with standard ISO threaded (1.375x24tpi) fixed gear hubs. Recommended for the use with narrow 6 to 9-speed 3/32" chains.
Note: The Surly Dingle Cog has to be used with alockring , which isnot included in delivery .
