Q & A
Reviews

The 1x 10 drivetrain setup is becoming ever more popular, and now with the introduction of the e*thirteen Extended Range EX Cog you can get the perfect 1x setup using your current drivetrain, no expensive upgrade, no faffing about. 

Giving you a larger gear range and the ability to switch to a single front chainring not only helps you keep the cost down, but also your weight (well, the bikes - we don't think it will have any effect on your weight). 

So how does it work?

Simple really, whip off your cassette drop the EX Cog on the back, remove the 15t or 17t cog from your cassette and pop the rest back in place. Hey presto you've got a snazzy new 1x drivetrain, a larger gear range and the envy of your mates. (see below for full details on how to fit)

Why different options?

Shimano and SRAM cassettes are timed and ramped differently, and as such each EX Cog is designed to work in harmony with each brands original setup.

The EX Cog comes in 40T and 42T for use with Shimano cassettes and a 42T only for SRAM cassettes.

Included in the pack is a longer, replacement B-Limit screw for your derailleurs. Your current one won't be long enough to obtain the best shifting up to the new cog.
