Ti to fly.

When thinking of bejeweled mountain bike components, King's storied headsets and Salsa's timeless quick-releases quickly come to mind. However, given Niner's acute attention to detail and undeniable quality, we expect the Cogalicious RDO to quickly join those ranks.

Constructed from 6AL/4V titanium, the Cogalicious RDO spins with a hardness that exceeds its alloy counterparts. This translates to both longer chain and cog life under the rigors of single speed riding. Further adding to the component longevity is a wide base that evenly distributes loads against freehub bodies. This wide base also allows for fine tuning of the chain line, as the teeth are slightly offset from the base.

The Niner Cogalicious RDO is available in one color and in six sizes from 17 to 22 teeth. The RDO also comes with a lightweight alloy spacer kit and lockring.

  • 6AL/4V titanium alloy
  • Thick offset base
  • Comes with alloy spacers and lockring kit
  • Reusable Niner tin included
  • Available in 17, 18, 19, 20, 21, and 22-tooth variants

Shave Some Weight Add Some Bling

This is an awesome and extremely lightweight for your SS setup. The cog is very well thought out, looks amazing, and is very durable. You can be a single speed luddite and still use awesome technology like this.
