RockShox Flight Attendant technology automatically adjusts mountain bike suspension
Even though mountain bikers can manually adjust their bike’s suspension settings, most of them don’t do it constantly on every ride. This is where the new RockShox Flight Attendant system comes in, as it automatically adjusts the front and rear suspension as needed.
For now at least, Flight Attendant is only factory installed on some forks and shocks, on some enduro Specialized, Canyon, Trek and YT bikes. It is currently not available as an aftermarket add-on.
The system consists of three sensor modules, respectively located on the top of a fork leg, on the bottom bracket and on the rear shock absorber. The three communicate wirelessly with each other via AXS technology from parent company SRAM. The fork-mounted “control” module is essentially the boss of the configuration.
While the bike is in motion, the system continuously detects when pedaling is in progress, when bumps in the trail are encountered, and when there is an uphill or downhill run. It responds in milliseconds by setting the front and rear compression damping to one of three modes: open, locked, or pedal.
Open – suitably enough – leaves the suspension wide open, so its full travel is available to absorb impact on the descent. Lock-up is the opposite, in that it rocks the suspension to its firmest setting, so that more of the rider’s pedaling power can be used while they are climbing or riding smooth roads. The pedal is a compromise between these two extremes, keeping the suspension semi-firm in order to offer some shock absorption and a still decent degree of pedaling efficiency.
Using an app or push-button controls on the control module, riders can configure the system to be more or less geared to one of the modes. They can also hold the system in one mode, switch it to another mode, or manually adjust the performance of the fork and shock.
And no, Flight Attendant is not the first system of its kind. Fox’s Live Valve setup offers similar functionality, while Magura’s eLECT module does more or less the same, but only for the fork.
