JET 9: A trail bike you can trust.
Our best selling trail bike on a budget that won’t break the bank. Updated, 120mm-travel JET 9 frame geometry places the rider in the sweet spot on the bike, offering better balance, better control and an overall better ride experience. With Boost spacing for increased tire clearance and additional wheel options, the redesigned JET 9 rides like it has more travel than it does without sacrificing efficiency on the climbs.
Light where it's right, built strong to go long
With 120mm of tuned CVA suspension and trail-ready frame geometry, the famous JET 9 platform is the most versatile in our lineup. And thanks to an affordable aluminum frame, carefully decorated with SRAM’s outperforming NX Eagle component group, the JET 9 is now one of our most accessible bikes as well.
Thanks to longer reach, a slack 67-degree head tube angle, short 50mm stem, and short 434mm chainstays, the JET 9 is more stable at speed, more confident dropping into steep lines, and more agile around corners. 130mm of suspension fork travel will help to get you out of trouble if you get in over your head on a sharp drop. And when the music stops and it’s time to pedal back uphill, the steep, 74.5-degree seat tube angle keeps you centered over the pedals for more efficient cranking.
Niner’s Constantly Varying Arc, or CVA™, suspension design is a short dual-link, four-bar system unique to Niner, developed in house and patented. It’s built to be supple yet stable, controlling unwanted suspension movement with calibrated anti-squat, yet remaining active while climbing and descending.
CVA suspension is perfectly balanced, so the result is stable yet supple, active, ground-hugging traction in every situation - cranking uphill, ripping downhill, and everywhere in between.
CVA suspensionSupple yet stable, and the confidence to drop into gnarly lines, knowing you’ll get consistency and control from top to bottom: that’s CVA suspension. Read More
