Singlespeed Rear Cog 12T-14T.

No more one-size-fits-all gearing!

Rear cog choices to change gearing on Yoji 14" and 16". 

12T - A direct replacement for the stock 12T on the Yoji models

13T - Makes gearing 8.3% easier

14T - Makes gearing 16.7% easier

Want to push harder gears? Consider putting on a larger front chainring.  Most 64mm BCD "granny" gears from the mountain bike world will fit the Yoji!
