RockShox Pike RCT3
$879.00
It is the new-school all-mountain and enduro riders' weapon of choice. It has received critical acclaim by the global mountain-bike media. It came out of the box and marched its way to an Enduro World Series overall title. And with good reason. PIKE was engineered to provide the plushest, most high-performance ride quality imaginable. Its Charger Damper with Rapid Recovery keeps you riding high in the travel where the feel is plushest, and maintains your bike's natural geometry. Its stiffness-to-weight-to-travel ratios are unbeatable, meaning you get a lot more from a lot less. Better control from fewer and more intuitive rider inputs allow you to charge harder, which equals time and energy for more laps. If all-mountain riding and enduro racing are how you describe a good day in the saddle, then PIKE should be on your ride.
