Excuse the brag, but we’ve really outdone ourselves here. Proving that true trail-taming capability doesn’t have to come at an intimidating price, the Rockhopper Expert is the culmination of 30 years of redefining the relationship between value and performance.

Start with a painstakingly engineered Premium A1 Aluminum frame, add in modern geometry that keeps one eye on efficiency and the other on confident capability and you have the rock-solid foundation of our best Rockhopper yet.

Pair that with a parts list that just doesn’t quit (...can we get a shoutout for RockShox’s Judy SoloAir fork and SRAM’s always-in-charge Level hydraulic disc brakes?) and you have a tubeless-ready, SRAM Eagle 1x12-equipped Rockhopper that’s absolutely prepared to fly.

  • 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.
  • A breath of fresh air at this price point—and plenty north of it, RockShox’s Judy SoloAir brings air-sprung sensitivity and performance to the masses with a killer value proposition: more bang, less buck. The TurnKey damper deftly dishes out travel letting you focus on what’s ahead.
  • Soar up climbs and dive down descents with SRAM's ultra-wide-range SX Eagle 1x12 drivetrain.
  • Tubeless-ready rims and tires keep your options open and traction on-call.

Great Frame and Fork

In my opinion the frame and fork are great, however the groupset (sx) is horrible. The derailer is plastic and after one ride has major issues shifting. Get the Elite model with Deore. It’s cheaper with the same frame and fork and has parts that will actually work.

What a shredder!!

This bike is the best it glides through the trail like nothing, rips through berms, and absolutely demolishes jumps and drops. Good for both long distance trips and shredding the trails. The 1x12 drive train really helps on those long single tracks and climbs. 10 out of 10 recommend.
