Item # NNR0039

The new miracle-metal.

It's pretty amazing what manufacturers are able to do with aluminum these days. 180 grams used to be lightweight for a stem. Now that would be a pig. And don't think that strength has been sacrificed–these new stems are strong enough to handle anything that modern freeriders can throw at them. The Niner RDO Stem is a perfect example of intelligent design at work. Niner put the right material in the right places for a stem that weighs an incredible 115 grams–and that's the 110mm length.

A high-quality stem is a great upgrade for any bike. It takes weight off the front end while adding safety, good looks, and, in some cases, a correct fit. The Niner RDO stem comes in a sexy gloss black finish with accents in four different color choices. It comes in the four most popular sizes for XC and all-mountain riding. The tried-and-true two-bolt steerer tube clamp and four-bolt handlebar clamp are strong enough to be used to race motocross, but remain simple and lightweight.

The Niner RDO Stem comes in gloss Black with Moondust Grey, Tangerine, Green, or Red accents. It is available in 80mm, 90mm, 100mm, or 110mm lengths.

  • Aluminum construction
  • Two-bolt steerer tube clamp
  • Four-bolt handlebar clamp
  • 115g in the 110mm length

Nice Build

  • Familiarity: I've put it through the wringer

Looks nice, bolts are painted, surface is shiny. Color options are great. Compliments the RDO seatpost very well. Fours stars because, really, what does a 5-star stem feel like? This one is as good as any out there.

Nice part.

Well made with an excellent finish. Perfect compliment to Niner carbon bars.
