Switching it up.

For a while, aluminum was the red-headed stepchild of high-performance bike components, but that's all changing with gear like the Niner RDO Stem. It's seriously light, at just 115g in the largest 110mm length, and strong enough to charge anything you feel like pointing your bike at. Two bolts lock onto the steerer tube, four more exercise a kung-fu grip on your handlebars, and the glossy finish looks killer on any bike.

The Perfect Connection

  • Familiarity: I've put it through the wringer

Connecting your fork to your bars is a pretty utilitarian task, but the Niner RDO stem does it in style. The stem is light and provides just enough pop to make your ride stand out. I love the carefully coordinated graphics, designed to go well with a broad range of frame colors. I have had zero issues with the stem after installing it over a month ago.

Great Stem

Love Niner products, this is my second niner rdo stem for my second build. Its not carbon but its super light and strong. Love this stem!

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.
