Better performance. Better value. Better Rockhopper. By tapping the fit and handling advantages of pairing each rider with their ideal wheel size and suspension that works its hardest for everyone thanks to our size-specific Rx Tune, we’ve baked in added performance to the all-new Rockhopper without dialing up the price.

microSHIFT's robust 2x8 drivetrain can handle everything you’re throwing down while confident braking from Radius CX7 mechanical disc brakes seals the deal of the century.

  • A heart of gold, presented in our lightweight yet durable Premium A1 Aluminum, the Rockhopper features butted aluminum tubes in order to keep weight low and strength high, all while providing increased standover clearance, slick internal cable routing and dropper-post compatibility. With the goal of making sure that the Rockhopper offers both the best fit and best performance for every person, no matter their measure, we’ve paired each Rockhopper frame size with the optimal wheel size. The result is a Rockhopper to fit every rider and the assurance that every Rockhopper is rolling on the best-handling wheel for its frame size.

  • With Rx Tune on Rockhopper, the SR Suntour XCE brings size-specific travel and spring rates to the show in a performance that’s sure to impress while also ensuring consistent geometry, handling and suspension performance, regardless of frame size.

  • Radius CX-7 disc brakes offer confident, consistent braking in any trail condition.

  • A durable Formula freehub and SunRace 8-speed cassette keep you rolling smoothly without putting up a fuss.

Walmart forks?

I have a 2020 29er Rockhopper Comp and I love the bike it is perfect for beginners and intermediate riders, however the Walmart $69-$89 Suntour "xct" forks the you guys putting on these $1000+ bikes are and is highly disappointing 👎I've had nothing but problems with mine I hope that when I decide to buy my next one this year it will have better forks Specialized is the only bike I buy and ride come guys don't skimp out on the forks besides the tire it's like jewelry its the first thing people look at and draw their opinion from about the rest of the bike I mean cheap forks, cheap made bike, less customers, less money for growth thanks for taking the time to read my review.
