Lapierre XR 929 (2015) is a 29er dual suspension mountain bike, with Lapierre's revolutionary e:i shock technology. The Shock is driven by electronics, taking into account your terrain and pedaling cadence. The 2015 model also features a new RockShox RS1 inverted suspension fork, technology only available on World Cup quality bikes.
The 'upside down' fork is similar to forks seen on motorbikes, whereby the wheel and stanchion pushes up into the fork to absorb shock, rather than the bike pushing down. This means an oversized fork which can be designed much thicker, giving greatly improved lateral stiffness. The seals in an inverted fork are also constantly being lubricated, which also greatly improves compliance over small bumps. This is all achieved while still reducing overall weight in line with the standards of highest level competition.
The e:i Shock Auto system is made up of several components :
  • 1 computer placed on the side of the stem, with a control button and an LED light to indicate the mode chosen and the position of the shock.
  • 1 Rock Shox Monarch RT3 Relay shock with motor.
  • 3 captors : 1 accelerometer on the stem, 1 accelerometer on the fork and 1 captor for pedaling cadence on the bottom bracket.
  • 1 cyclindrical battery (25h autonomy)
The two accelerometers measure the movements of the fork (speed and intensity of shocks) and the captor on the bottom bracket measures the pedaling frequency.  All this data is transmitted immediately to the computer which evaluates the terrain and the pedaling cadence. In automatic mode,  the computer puts the shock into the correct position to ensure the suspension is in the ideal position for the rider. 

It takes just one tenth of a second for the information to be sent from the three captors to the computer, and onto the shock (the time taken for the back wheel to arrive at the position of the front wheel when travelling at 36 km/h). Ultra-fast, the rear suspension adapts to the terrain covered by the front wheel in record time.

If a large obstacle is detected by the fork accelerometers, the shock opens instantaneously, before the rear wheel reaches the obstacle.

Thanks to its 100 mm suspension, XR 929 is very comfortable over small bumps, and with 29” wheels, enjoys extraordinary rollover capacity and grip for a cross country bike. All Lapierre bikes are conceived, developed, and tested, by our experienced technicians in our historic site in Dijon, France.

Painstaking attention to detail and passion for a better, more intuitive bike have seen Lapierre at the leading edge of technological development for decades.
