STATUS 2 finds the boundaries of mountain bikes and pushes past them. Is it a trail bike? Yes. Park bike? Yep. Cruise to the convenience store and stop for a stealth session on a concrete wall ride? Oh yeah. STATUS 2 is a bike meant to be ridden, however or wherever you ride. Whether you are on the trails, at the bike park, in the streets, or just cutting turns with your friends on a local hill, the STATUS 2 will allow you to ride your way. BUILT BY RIDERS: Each build starts with a super strong M5 alloy chassis and tough alloy wheels. Stout suspension, powerful brakes, and popular drivetrain options round out these builds to catch big hits, pedal smooth, and provide a ton of stoppage. It’s not for the gram counter—it’s for those riders who push the boundaries of progression and come back for more. RIDE DYNAMICS TUNED: Before showing up at your doorstep or local bike shop, each STATUS 2 gets a special shock tune from our Specialized Ride Dynamics team—a group that eats, sleeps, and breathes mountain bike suspension. The characteristics of the shock are designed to complement the kinematics of the new STATUS 2 perfectly. LET’S GET PERSONAL: Each model of STATUS 2 features neatly packaged flip chips (located on the Horst pivot link, close to the rear axle) that allow the rider to finely tune the frame’s geometry to their desired ride or terrain. Bikes ship in the high position but can be ‘flipped’ to lower and slacker—8 mm lower bottom bracket and half a degree slacker head tube angle. - 100% Redesigned durable alloy chassis - New, more durable alloy rims - Horst Link geometry adjust flip chip - Updated geometry for more usability - Curated parts spec for your desired ride experience

From loam to chunder, alpine peaks to desert rock, this trail slayer has a 29-inch front wheel and 27.5-inch rear for the ultimate combo of quickness and control. With 145mm of rear suspension, a beefy 160mm fork, and adjustable geometry, it’s ready to let loose on black diamond descents. Updated suspension This “SX” series features all-new Maestro rear suspension with added travel (145mm) for technical singletrack and rugged descents. The trunnion mount shock and Advanced Forged Composite rocker arm combine for a longer stroke that has a smooth, active feel, plus greater stiffness in the chassis for precision control. The rear suspension is paired with a longer travel 160mm fork, giving riders superior confidence and control on the descents. Adjustable trail geometry A three-position Maestro flip chip lets riders dial in frame geometry to suit their riding style and terrain. The high setting adds more ground clearance, a good option for tight, technical terrain. In the low setting, the head tube gets slacker and the bottom bracket drops, ideal for confident handling at higher speeds. The middle position is neutral. In addition, a new headset flip chip adjusts reach so you can easily achieve your preferred positioning. Mixed wheel setup A 29-inch front wheel provides speed, stability and front-end control on rough, technical trails. A 27.5-inch rear wheel adds agility and maneuverability to help riders rail corners, pop over features and show off their style.

If in doubt, take a Bronson out From flat out on the TR to fully flat over a table, if you wanna send it the Bronson delivers. The 150mm-travel bike can go deep on any landing and the VPP suspension design makes sure that there's no wasted energy when heading back up for another go. If you value style at speed or want to have fun feeling fast, then mixed wheels (29" up front, 27.5" out back) are the right choice. The larger front wheel provides more traction and stability that'll make you feel more confident squaring off the turns and diving for the inside lines. But a 27.5-inch tire in the rear means this bike still loves getting up on the back wheel and into the air.
