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 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. - A heart of gold, presented in our lightweight yet durable Premium A1 Aluminum, the Rockhopper's butted aluminum frame features hydroformed top and downtubes 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. - 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.

Lowside is the bike that gets you across town for a quick rip on singletrack, then over to the bar for a night out. Your BMX Bike All Grown Up Lowside is like the grownup version of the bike you rode when you were a kid and still had hopes and dreams and some semblance of ambition. It's just as happy riding singletrack as it is parked outside your favorite drinking establishment. Lowside is a single speed mountain bike. Singlespeeding has been a part of Surly's DNA since day one when we launched the 1x1 Rat Ride. After a lot of Homie Fall Fests and more feats of strength than we can recall, we decided to discontinue it a couple years back. Lowside picks up right where the 1x1 left off. "Some have dubbed the Lowside the ultimate pub cruiser." - Modern trail standards: dropper post compatibility, 44mm headtube, Gnot-Boost rear spacing, thru-axles - Compatibility with most mountain bike standards makes it the perfect parts bin bike (no rim brakes allowed though) - Spec'd in alternating years with 26 x 3" or 27.5 x 2.8" tires, the Lowside remains capable of running either option
