Specialized Rockhopper Sport 29 gloss pine green/obsidian MTB hardtail

The Rockhopper Sport is a true racer and not a bankrupt bike: It sets new standards in performance while being easy on your wallet.

With Tektro M275 hydraulic disc brakes, Shimano CUES drivetrain, and an SR SunTour XCM fork built for peak performance, the Rockhopper Sport can win every Sunday—and the rest of the week, too.

The Rockhopper's double-butted aluminum frame has a heart of gold, crafted from our lightweight yet durable Premium A1 Aluminum. It features hydroformed top and down tubes for low weight and high strength. It also offers a higher standover height, sleek internal cable routing, and dropper post compatibility.

To ensure the Rockhopper offers the best fit and performance for everyone, regardless of size, we paired each Rockhopper frame size with the optimal wheel size. The result is a Rockhopper for every rider and the confidence that every Rockhopper is riding the optimal wheel for their frame size.

We're bringing our Rx Tune to the Rockhopper for the first time. The lockout-equipped SR Suntour XCM with individual multi-circuit damping offers size-specific travel and spring rates for impressive performance, while ensuring consistent geometry, handling, and suspension performance—regardless of frame and wheel size.

The powerful Tektro hydraulic disc brakes have a powerful bite, but deliver their power with a refined, intuitive feel—a total package that goes far beyond its performance class.

A durable 1x Shimano drivetrain with a wide gear ratio and a clutch-capable rear derailleur ensure a quiet ride—and secure chain retention.

Combine Formula's rock-solid hubs with our 25mm inner diameter Specialized hookless rims for a robust, lightweight, and durable wheelset.
