Smooth your ride.

The Niner RDO Carbon Seatpost reduces harsh vibration when you're cruising over rough terrain, thanks to what Niner dubs an "Unstiff" carbon layup. Whether you're riding a hardtail or full-suspension rig, it's designed to deflect up to twice as much shock and vibration feedback compared to regular post designs, smoothing out bumps and rocky trails for less fatigue. Note that this zero-offset post comes with a simple, easy-to-adjust two-bolt clamp with an alloy head for strength and durability.

Light , looks great, clamping mechanics works great, actually functional as it flexes a tiny bit and absorbs some trail chatter. Perfect on my jet 9 RDO

Lives up to its reputation

  • Familiarity: I've put it through the wringer

I have a Niner MCR (steel hardtail), and added it last season. It does provide a nice little bit of flex, and helped to take a bit of the edge off. I am happy to have purchased it.

Awesome Seatpost!

Seatpost is great, very stiff but at the same time it gives when it needs to and absorbs a great amount of shock. Love niner equipment, wouldn't give up niner for any other brand.

Looks good, feels fine

  • Familiarity: I've put it through the wringer

I'm happy with this....shiny finish, holds the seat very securely. Easy to adjust the to & fro, tip and tilt with the two seatpost bolts. Your seat design pending, the seatpost bolts are long'ish, and could ride near the underside of your seat. Color options are a great touch with their products. I'm not running this seatpost extended very far, so the compliance is probably minimal. This component goes un-noticed, perhaps that is a sign it is well done. Four stars, as it is very pricey, did not come with carbon assembly grease (for that price, should have) and no stickers...

I ride my krampus to go everywhere and its amazing what difference this seat post makes. It makes staying on the saddle much more comfortable while climbing.
