Surly Single Cassette Cog 3/32 17T 3B the first dual lens PitOur cassette cogs are designed first and foremost for singlespeeding, but being that were Surly, we bumped up the versatility a bit. At the base, the cogs are 4. 35mm wide, which allows you to stack a few of them up for a simplified multi speed drivetrain. Use a 9 speed derailleur if you do that. Machined from SCM415 Chromoly steel Heat treated and chrome plated Compatible with 6 to 9 speed 3 32" chains Available in 13t22t
