Niner

Cogalicious RDO

Not only is the Niner Cogalicious RDO a beautifully crafted cog that's sure to please the most discerning of single-speed aficionados, but it has the performance to match, thanks to its exceptionally hard 6AL/4V titanium alloy. Translated to real-world performance, you'll appreciate the enhanced chain and cog life exhibited by 6AL/4V titanium. Further increasing longevity, the thick offset base evenly distributes pressure against the freehub body, also allowing for chain fine-tuning with its slightly offset teeth.

Note that this kit comes with alloy spacers and lockring, as well as a slick reusable Niner tin to match the cog's sleek and shiny appearance. It's available in 17, 18, 19, 20, 21, and 22-tooth variants.
