The PUSH Fork is Finally Here - The Inside Line MTB Podcast

Watch our video and see photos of the fork on Vital MTB and our YouTube channel.

Thank you Maxxis Tires, FOX Suspension and Jenson USA for making The Inside Line possible.

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 eventually showed the fork at the Sea Otter Classic. A couple months turned into 4, then 7 then 8. Fast-forward 12 months later, and the fork is now available to the public.

At $2,600 USD, the coil-sprung Nine.One is made in the USA at the PUSH factory in Colorado. It features 140-170mm of user-adjustable travel in 10mm increments and uses modular axle lugs that can run 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 updated 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.
