Surly Cassette Cog

9 Speed spaced, these cogs can be run 9-speed or less, together with Shimano 9-Spd gear shifter systems.
Teeth profiles are straight forward, making them ideal for Single Speed applications, however, with no twists or ramps etc, the gear shifting will not be as slick as with regular Shimano cogs when used in a multiple cog line-up.
The large foot print caused by built-in spacing at the base of these machined cogs gives a larger foothold on the cassette body, making these a premium selection for Single Speed or multi-speed use with reduced risk of torque transfer damage to the cassette hub body. (Note: This point is especially important with Alloy or Ti Cassette bodies)

  PLEASE NOTE: When used in non-9 set-up, additional Cassette spacers wil be required to fill the cassette body
