SURLY Cassette Cogs (22T) | Highly Durable Chromoly Cog for Single Speed Conversions
Because it's simple, you want to choose something you can rely on.
The SURLY Cassette Cogs 22T are highly durable cogs designed to convert cassette hubs to single-speed specifications. Despite their simple construction, thorough attention to materials and processing ensures reliability for long-term, worry-free use.
They are made from SCM415 chromoly steel and are machined. Furthermore, hardening and chrome plating treatments provide excellent wear resistance. They demonstrate high durability for daily use, as well as for demanding commuting and touring applications.
Compatible with Shimano-type cassette freehubs, they can be installed on many wheels. The tooth profile, optimized for single-speed use, also offers excellent chain retention, supporting stable drivetrain performance.
Additionally, a wide contact area with the freehub reduces the likelihood of biting and deformation that can occur with aluminum freehubs. The 22T allows for a relatively light gear ratio, making it an easy-to-use tooth count suitable for a wide range of applications from city riding to touring.
