FL-X Study

30 % less vibration through the SQlab FL-X technology

Experimental setup

The acceleration was recorded with two triaxial acceleration sensors at a frequency of 400 Hz (400 measurements per second). In order to determine the difference between the handlebar end and the centre of the handlebar, one sensor was mounted centrally on the handlebar and a second sensor on the handlebar end.

Test procedure

The test lap was ridden by Max Holz SQlab Category Manager Performance and Marathon Winner 2018 in Riva, Willingen and Leogang. The course included root sections, downhill and uphill sections as well as drops of different heights.

Analysis 

The diagram shows the reduction of the load in percent. It can clearly be seen that the SQlab 311 FL-X has a constantly high damping capacity between 18% and 31%.

Result

At accelerations of up to 50 m/s² (which corresponds to approx. 5g, i.e. 5 times the force of gravity), the SQlab 311 FL-X reduces the loads on the hand arm system by 18% to 20%. The other handlebars tested can only "work" a little or not at all at these accelerations and thus reduce the load only insignificantly.

These accelerations/impacts occur frequently in mountain biking, e.g. in root passages or braking bumps. The mountain bike specific problem "arm pump" is evident. The result is a numbness of the fingers and early fatigue. At higher loads, the 3OX Carbon reaches the highest damping depending on the area of use.
