Sugino Track Cog 16t, 17t, 18t Set - Silver

This track cog set from Sugino allows you to try different ratios on the street, without the need to use a chain whip tool.
You get a 16T, 17T and an 18T cog all included.
The threading is standard, to fit track hubs such as Shimano Dura Ace, and Gran Compe.
A road bottom bracket tool (such as the Park Tool bbt-9) is used for securing both the cog and lockring.
You can have a 16T for the track, 17T and 18T for the city, for example.
These cogs are available in black and silver.
Usual top quality as you would expect from Sugino!
