All barn-burner and no benchwarmer, the Rockhopper Sport throws out the playbook when it comes to putting performance points on the board while playing some serious defense on behalf of your wallet. Game-ready with Tektro M275 hydraulic disc brakes, Shimano CUES shifting, and an SR SunTour XCM fork that's built to hustle, the Rockhopper Sport can tack up the win on any given Sunday—and the rest of the week too for that matter. - A heart of gold, presented in our lightweight yet durable Premium A1 Aluminum, the Rockhopper's butted aluminum frame features hydroformed top and downtubes to keep weight low and strength high, all while providing increased standover clearance, slick internal cable routing, and dropper-post compatibility. - To ensure 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. - Bringing our Rx Tune to Rockhopper for the very first time, the lockout-equipped SR Suntour XCM with custom Multi-Circuit damping 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 or wheel size. - Beautifully beastly, Tektro hydraulic disc brakes pack a mean bite but deliver their power with a refined, intuitive feel to make for a package that punches way above its pay grade. - Keep things simple with a durable 1x Shimano drivetrain with plenty of range and a clutch-equipped rear derailleur that keeps your ride quiet—and your chain on. - Pair dead-reliable hubs from Formula with our 25-millimeter internal diameter, hookless Specialized rims for a strong, light, and durable wheelset hat trick. Wheel size: Sizes X-Small – Small: 27.5-inch Sizes Medium – X-Large: 29-inch

Sirrus X is your ticket to riding more, and to places you never imagined possible. It's a comfortable, capable, "let's do stuff" kind of bike that will inspire you to ride more than you ever have before. With bigger, confidence inspiring tires, a slightly more upright riding position, a super intuitive one-by drivetrain, and plenty of mounts for racks and fenders—it's more than just a solid partner on pavement. Sirrus X is a dialed option when it's time to hit some gravel. We've also equipped every Sirrus X with next-level comfort from our scientifically tested and ergonomically engineered Shared Platform Body Geometry saddle, handgrips, and pedals. - Even lighter (1.6 lbs/.8kg) than Sirrus X 2.0, and faster thanks to an added A1 alloy fork. - More powerful hydraulic brakes and premium two-piece crank design for enhanced braking power and durability in tough conditions. - Wide-range 1x9 MicroSHIFT drivetrain with a 11-42t cassette gives excellent range on any road.
