For years, bicycle builders tried to keep mountain bike shock plush, but not bouncy, with "trail mode" and "brain" shock settings and add-ons. It was all a compromise. Now, Rockshox has designed the Electronic Intelligence (EI) Shock electronic suspension system for bike manufacturer Lapierre. The three-position rear shock is computer-controlled. Accelerometers and sensors transmit to a Servomotor that adjusts the rear shock within 0.1 seconds of the front shock's terrain report. Your control center is handlebar-mounted and looks like a cycle computer. It's a game changer, for sure. Available on Spicy, Zesty, and XR Lapierre Models. [$4,000-$8,000;]
