Innovation

We put numbers through sensations. Do you want to join us?

2013-08-21

In our Disusbi innovation project we are in a stage where we are subjecting to various models in the trail bike category to extensive testing to analyze the performance of their suspensions as well as their pedaling efficiency.

How are we carrying all this out? You can’t miss what’s coming next. We never stop innovating!

Suspension testing

Thanks to the coordinated efforts by CEIT (Centre for Studies and Technical Research of Gipuzkoa) responsible for months of the current phase of sensing of all bikes that we are currently testing, with the support and advice of the IBV (Institute of Biomechanics of Valencia), we have been testing five bikes from five leading brands to subject them to the same kind of tests and analysis.

In these tests, and following the guidelines set by the IBV, the five bicycle models have been adapted to be tested by the same user, so that in each and every one of them you’ll find the same position as you pedal, the same distance between saddle and handlebar and even the same handlebar and grips on every bike in order to achieve the best fit by the rider on each bike and perform these tests as objective, precise and methodical as possible.

Specific tests: Dropping steps and riding over bumps

Test 1: Dropping different 20 and 40 cms drops at a time at different speeds to check the absorption and performance of the bike in this kind of situation. Test 2: Riding over two sets of three fixed obstacles performed at different speeds (15 and 25 km/h) recording the performance of suspensions in each case.

Test on the treadmill

Hegalak sports center in San Sebastian has a treadmill where we could meet face to face and analyze the performance of various models of bikes together. The goal is to compare these different bikes in the same scenario to get the most objective and clear as possible pedaling efficiency in situations such as riding on a flat ground or uphill. The rider, once he is balanced and in control, has to follow a predetermined protocol test where variables such as speed, the slope of the treadmill, etc, are modified, pedaling at different speeds with different gears, faster or slower cadence, even changing the parameters for the compression adjustment on the rear shock.

The rider without stopping pedaling answers a series of questions about the perception of his effort at all times, while simultaneously all data that sensors transmit to us which are recorded in real time, are sent to a computer where we can check the performance of the bike and suspension at all times. These data from the different sensors, accelerometers and gyroscopes which are placed on key areas on every bicycle, are then analyzed to determine with the most precise accuracy and as objectively as possible the performance of each bike. A laborious job that takes several weeks of investigation putting numbers through sensations.
