How about a carbon XC bike that doesn't back down when you drop into some gnar? Rocky's Thunderbolt 750 MSL delivers XC lightness with a Smoothwall carbon frame, then, things get interesting. Add a relatively slack head angle, 27.5-inch wheels, and 120mm of travel front and rear courtesy of Fox, and technical sections just got a lot easier. Go ahead, charge it — you're fully equipped to take the hard line with Shimano SLX/XT 2x10 gearing and Shimano's superb SLX brakes. Race Face is British Columbia-born and bred the same as Rocky Mountain, so of course the cranks, saddle, stem, post, and wide Evolve bars are exceptionally capable. Forget about backing down, get on with it.
Rocky Mountain's Ride-9 system enables you to customize the geometry and rear suspension rate with two interlocking inserts that allow for nine different positions.
By moving the shock forward, the geometry slackens and the suspension rate becomes more progressive, giving a nice ramp up for bottomless-feeling travel (image above, dotted line). It’s ideal for aggressive downhill riding. When you move the shock backwards, the geometry becomes quicker and the suspension more supple (blue line), which is great for ripping around technical singletrack and increasing climbing traction.
When you move the shock upwards (solid black) it allows lighter riders to run shocks at higher pressures, and moving the shock downwards (red line) allows a heavier rider to run lower shock pressures. So no matter what you weigh, this allows you to run the rear shock in the sweet spot with correct sag for smooth, consistent suspension.
|Rocky Mountain's Smoothwall Carbon construction creates a frame that is just as perfect on the inside as the outside. Rocky Mountain uses an inner mold to reduce excess resin, fibers and filler to create a super high fiber-to resin ratio. The result is an incredibly lightweight, stiff and responsive ride with incredible strength.|
Rocky Mountain's Smoothlink suspension places the rear chainstay pivot above the rear axle, keeping the chain torque line parallel to the linkage. The benefit? The rear suspension is always active, bob-free, and delivers a wonderful bottomless feel, no matter what gear you're in.
