RockShox: Unlike a dirt-bike, the new Monarch Plus rear shock has no rev-limiter. Because with its fusion of the Monarch’s exemplary light weight with an all-new Solo Air system, and a damper design similar to the Vivid Air, the Plus will have you bombing all-mountain trails like it was born to downhill. In other words, you’re going to need some serious stopping power to slow this freight train down. So it might be time to look at some four-piston brakes for your steed.Shock bodies in Fast BlackDebonAir™ spring optionPerfect Match for Pike
