Close Up Photos of Lapierre x Rockshox I.E Electronic Automatic Suspension Damping System

2013 Lapierre Rockshox IE electronic automatic adjusting mountain bike suspension

We got the tech rundown from Rockshox’s product manager a few days ago, and now we have some glamour shots of the finished product as it’ll come on Lapierre’s 2013 mountain bikes.

Called I.E, the system uses two front mounted accelerometers, one on the fork lowers and the other inside the computer on the top of the stem, along with magnetic sensors in the crank’s spindle to determine pedaling speed and impact forces to automatically (and virtually instantly) adjust rear shock settings for maximum performance.

One thing that’s immediately noticeable is how much smaller the actuator box is Fox’s iRD electronic remote control shock, though they both do the same thing.

The computer mounts directly above the stem via a top-cap attachment bolted into the steerer tube. This keeps the forces its built-in accelerometer is sensing constant, as opposed to having it mounted in different locations if it were going on the bar or stem.

The lower accelerometer doubles as the speed sensor.

The battery is about the same size as the Di2 unit. Lapierre’s different bikes use different shock layouts depending on travel.

A simple up/down/mode control button lets you cycle through the modes manually and adjust the system.

Both experienced journalists like RC from PB or the guys from velovert are saying it’s working really really well. “Experienced” because they are familiar with the electronics from the past, like the K2 shocks in the late 90s (used one and it was not working that well imho).

But … it’s a plus €500 option on the bike. And one more thing, I want to see how it’s working against the most advanced “regular” shock in its category, aka the BOS vip’r.

Who thought it was a good idea to use a Fox fork for the photo-op? Sram wouldn’t mail them a rockshox?

@WillM I was thinking just the same thing!

…perhaps RS just don´t want to show the I.E Fork

I’m guessing that’s how the Lapierre bikes are actually spec’d.

Anyone remember the ‘no battery required’ advertising by SRAM as their (weak) response to Shimano DI2? Now batteries are OK?
