A tough, rigid thru-axle is just one of the upgrades that Niner offers on its RDO Carbon Rigid Fork, along with a strong, light, and responsive tapered head tube that'll let you rally through trails without worrying about collapsing your fork or feeling out of control.
Big wheels, high speeds, and strong disc brakes can combine to tweak flimsy forks out of alignment, which makes it really hard to hold your line while you're riding steep, high-speed trails. While suspension forks have been rocking burly thru-axles to fight off flex for years, rigid forks are only just catching up. Niner endowed the RDO Carbon with a rugged 15mm RockShox Maxle thru-axle to resists these torsional forces, so your wheel will track straighter and you'll be able to hold a reliable line under braking (and when you're opening the throttle).
The whole RDO Fork is made with Niner's secret sauce carbon fiber, proprietary layups, and tube architecture, so it's light, stiff, and highly responsive. A special carbon weave is designed to maximize carbon's dampening properties, too, so you don't feel like you're getting vibrated to death or bounced around like you're riding a steel fork. At the top, a tapered steering tube integrates seamlessly to provide precise and reliable control with plenty of strength, and its seamless integration reduces stress-prone bonds that can squeak, creak, or worse. Indeed, the RDO is burly enough that Niner doesn't even ship it with a weight limit—if you can ride it, you can ride it.

B00M, how you like that travel?
- Familiarity: I've put it through the wringer
Nothing makes me want to stand up and sprint on my hardtail like putting this fork on it. You'll be scared, at first, to ride your newly rigid bike as fast and rough as you did when it had a suspension fork on it, but you'll get over that. You'll flat or crash before anything happens to the fork, which seemed to by my first worry. I think we all forget how well these products are made and how hard you can ride modern equipment. The brake hose routing is nice, too.
What's the widest tire that this fork can accommodate?
2.4 inch .
Is this a direct replacement for the Rockshox Reba on my Stumpjumper Carbon HT? Do I need anything else to make the conversion?
Does the RDO fork include the headset? If not what is the part number for this item.
This fork does not come with the headset. You will need a tapered 1.125 - 1.5 tapered headset. Just make sure you select the headset that fits the frame you have. Feel free to contact our experts by calling 888-276-7130 or by chatting with them using our live chat feature. They can check into what headset your frame requires and help you find one that works.
