The PUSH FORK is Finally Here - Nine.One Upside Down MTB Fork Development Story and Details
54,436
Published 2024-02-29
Vital first rode a prototype PUSH Nine.One inverted mountain bike fork a year ago in February of 2023. The same day, we recorded an interview with PUSH owner, Darren Murphy, getting all the details about the fork before its release. At the time, the scheduled release for the Nine.One was only a couple months away and PUSH showed the fork at the Sea Otter Classic. A couple months turned into many months and fast-forward 12 months later, and the fork is now available to the public.
At $2,600 USD, the coil-sprung Nine.One is 100% made in the USA at the PUSH factory in Colorado. It features 140-170mm of user-adjustable travel, and uses modular axle lugs that can fit 27.5 or 29-inch wheels with built-in brake mounts for 180mm or 200mm rotors. The damping technology is that of the PUSH Elevensix shock and oil can be changed and serviced through bleed ports at the top of the fork.
While most riders can't comprehend spending that much money on a fork, Darren and PUSH set out to make a highly refined piece of suspension that can last and be adapted for years to come. We dive into why PUSH would make a fork, their philosophy on what makes good suspension, misconceptions of upside-down fork design, what took so long to finish production and why someone may want such an expensive MTB fork.

The details of this fork are next level! Well done PUSH 👏
-
Well done. Europeans already made high performance Enduro Mtb inverted fork, Intend (alu) in Germany and Brigth (mixed alu+carbon) in Italy
-
Wow, that was the most interesting product interview I have ever listened to. Well done PUSH. I think I am sold.
-
Amazing... Cant imagine the r&d costs. Ty Push for putting in the effort to actually contribute a real gem to the industry... Many will now copy and costs will drop.
-
I'll never have the means to buy this, but I'm glad it exists, even if it's mostly engineering porn. It's both a high performance component and a museum-worthy piece of art, hats off to Push🤘
-
Great interview! Thanks for taking time to put this together.
-
That was such an eye opening Interview, Darren's point about the parking lot tests being bullshit were really valid. The twisting effects happen underneath the wheel directly in line with the fork legs with very little leverage, and the bump sensitivity comes from below the front wheel, not from just pushing on your handlebars.
-
Bro did not want to say it weighs 6lbs 😂
-
Push is such a cool company. Great interview, boys. Thanks for the content 🙏 🤘
-
Keep videos like this coming!
-
great interview - thanks! 🤜
-
wow....love the looks....I bet it rides amazing!
-
This is a dentist E bikers dream.
-
MTB Fork Is Love. That was outstanding pieces of I had ever seen.
-
I've been riding the Rockshox RS1 on my Cube for over 6 years - carbon upper. VERY happy with it. Super efficient, minimal maintenance compared to normal forks, and although only 100mm, has held up well at UK trail centres, XC (of course) and even a tour of Mont Blanc where most other riders were on Enduro bikes 😁 No stanchion damage in that time.
-
Would love to try it. I like the all-out making the best they can make concept.
-
For a top line MIA fork, the price is completely reasonable. While I certainly don’t ride top tier, it’s nice to see a company really go for it like this.
-
49:18 Common misconception is that the "tube that goes inside of the other tube" is the stanchion. The stanchion is always the upper tube regardless of weather the fork is conventional or inverted.
-
I have my set already. I can say they are the most amazing looking piece of kit I've ever laid eyes on. Can't wait to test em out.
-
Great interveiw! Great to learn about the Push. Would love to try it someday. I have a wren and have enjoyed it. The push wpuld be a beast im sure of it!
