Wolf Tooth Components single speed conversion kit with a 19 tooth aluminum cog in immaculate condition. This kit was installed on an 11 speed Shimano freehub.
I have a Sram Eagle chain that was used in this setup. Check out my other listings.
This aluminum single speed cog features extra tall teeth for reliable chain retention when using chain tensioners. It is reversible and features a 4.5 mm width at the base that won't dig into your freehub body. Made in USA.
Cog model: AL-SS-ORG-COG19
The price of brand new was $100+ ($55 cog and ~$50 for spacers).
