Pendbox Technology

Less compromise, more pedaling power!

X-Flow, your new best friend for off road riding Pendbox allows for more freedom around the bottom bracket and more freedom for shock absorption. The results can be felt from the first pedal stroke:
- Better shock performance
via a more progressive suspension
-Better pedaling efficiency: no pedal bob
-A more stable ride
-Sag set-up made even easier
- More simple, compact
and lightweight than FPS2

 

PENDBOX® UNLIMITED POSSIBILITIES!

 

Launched in 2011 on the DH model, Lapierre’s new Pendbox technology is considered by many as a revolutionary rear suspension design. Proof positive: First time Sam Blenkinsop rode his new PendBox® bike on the World Cup race circuit, he won the qualifying round, finishing on the podium. That’s efficiency !

New for 2012 :

PendBox® for DH models and the all-new X-Flow With amazing pedaling capabilities, the PendBox® system was destined to be adapted to less travel for XC trail riding:
a new challenge for Lapierre engineers, who started working on the X-Flow project two years ago.

HOW DOES IT WORK ?

The pivoting point is positioned in such a way to eliminate pedal kick-back (calculated by our engineers using a mathematical model and confirmed during field tests).
• By moving, the floating bottom bracket keeps the chain taut and eliminates energy loss (a movement hardly noticeable while riding – approximately 5mm).
• The interaction between the floating bottom bracket and the rear swing arm creates an equilibrium point (SAG). See fig.2 When the rider pedals, a tension in the chain is created:
• This provokes the movement of the bottom bracket.
• And, because it’s connected, the rear swing arm is proportionally forced back to its equilibrium point (SAG).
The result of which eliminates pedal kick-back. See fig.1 and 3

TOTALLY ISOLATE PEDALING EFFICIENCY AND SHOCK ABSORPTION FOR IMPROVED PERFORMANCE

 

How do you combine the extreme efficiency of our FPS2 and OST+ suspension platforms and optimized shock absorption, without compromising either function, and still achieve improved performance? By isolating and dissociating pedaling efficiency and shock absorption. The new PendBox® suspension optimizes each one and eliminates pedal bob. Everything functions in total harmony, but independently, without any interference. Less compromise, more pedaling power!

X-Flow, your new best friend for off road riding Pendbox allows for more freedom around the bottom bracket and more freedom for shock absorption. The results can be felt from the first pedal stroke:
• Better shock performance via a more progressive suspension
• Better pedaling efficiency
• A more stable ride
