e-thirteen extender sprocket for Shimano and SRAM cassettes

July 23rd, 2014

By Adam Stonehouse

e-thirteen have recently launched the ex-cog range and are now offering an extended range cog for Shimano cassettes in as large as 42t. We found this short video clip that shows the ex-cog 42t in action shifting smooth as butter and providing that extra gear range you crave on those steep climbs.

 

 

The ex-cog is now available in black, red & blue in shimano fit 40t and 42t or SRAM fit 42t.

 

SRP £54.95
