Start number & Transponder attachment

How you mount it correctly

So we can tell you’re a Ring cyclist, all participants get seat post and helmet numbers. For detailed info on how to attach them, check out the video below and the info sheet from our timekeeper (in the starter kit). Participants without a start number should expect to be taken out of the race or at least get a penalty.

There is a small difference for the 24-hour teams: while for individual riders, public racers and gravel riders the transponder is part of the seat post number, the 24-hour teams receive it in a water bottle. This must be carried in the water bottle holder on the bike. Participants are responsible for alternative transport options. Tests have shown that transponder bottles also work when placed in the back pocket of your jersey. However, it is important that you do not put a jacket over them. This becomes particularly critical if, for example, a thick, wet jacket is placed over the transponder, as this significantly weakens the signal.
