The most recent style of mountain biking is a mixture of arduous uphill, downhill and cross country sections. These timed sections (stages) are linked by less strenuous intermediate sections. The winner of the race is the one with the lowest accumulated time. Set up the stages with your bike and backpack. Get live results. There is nothing easier then take your race time.

Using SPORTident AIR+

Based on the SPORTident ActiveCard the system AIR+ supports the special requirements of MTB Enduro. The contactless timekeeping allows a quick tracking and evaluation of the race. To stop at the beginning or the end of a stage is not required. SPORTident AIR+ additionally enables timekeeping and identification by passing SPORTident BS-11 stations configured in a gate mode. Gate mode configuration features higher time accuracy of up to 1/10 seconds.

Advantages for you as an organiser

Easy to set up

Easy and rapid installation even in areas where access is difficult, less personnel expenses due to fewer course marshals required.

Many features

The riders bring the data to the finish line. Many possibilities of evaluating and showing the data (e.g. live results at the course, Internet).


The stations will work without an external power source (rechargeable battery is integrated). Any time. Any location. Any weather.

Easy handling

The SIAC is compatible to the whole SPORTident system and can be used in any combination with the traditional SPORTident equipment.

To set up a station at the control point needs less then 30 seconds time and can be done by one person.


Each rider has to be equipped with a SPORTident ActiveCard (SIAC) for contactless timekeeping. With a specific mounting holder "bike" this card will be mounted at the bike (frame, handlebar or headset). Before starting, the SIAC has to be switched on. A successful timekeeping will not be possible if the SIAC is not activated. The activation of the SIAC is shown by a flashing green LED. SI-Stations in the AIR+ configuration have to be charged before application. SPORTident AIR+ is a real time system. SI-Stations should be synchronised by using a master clock shortly before application. To illustrate the application of the AIR+ configuration to the competitors it is recommended to set up a test course with some control points in the event centre. There, the athletes can test and monitor the feedback signals of the SIAC at different passing speeds.

This is the heading

SIAC supports fast registration of competitors to participate at a race. The standard SPORTident procedure CLEAR – CHECK – START – CONTROL(S) – FINISH remains when SPORTident AIR+ is used. During the race the SIAC stores the start and finish times of the stages. The successful registration of the checkpoints is indicated by an obvious optical and acoustic feedback signal. It is not necessary to collect the data at several points of the track. The deactivation of the SIAC is done with registering the finish time. Without a finish record the device deactivates itself 20 hours after having received last record.

Evaluation of the results

After the finish, race data stored in competitors SIAC have be read onto a computer for event evaluation. SIAC readout is possible at any time and not depending on SIAC's activation. Optionally, the data can be read out and transmitted by radio. Therefore to enable this, the checkpoints and the finish line can be equipped with a GSM modem. This allows to show the results data in real time and to present them on different media.
