Surly Singlespeed Cassette Cog
$45.99 - $49.00
Surly Singlespeed Cassette Cog Item # 2136111
Description
Surly's cassette cogs are designed first and foremost for singlespeeding, but being that they're Surly, they bumped up the versatility a bit. At the base, the cogs are 4.35 mm 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.
Specifications:
- Machined from SCM415 Chromoly steel
- Heat-treated and chrome-plated
- Compatible with 6 - 9-speed 3/32" chains
