How to attach a timing transponder

QCR races are chip timed. A wire laid across the road receives data from the transponder so be careful to attach it securely and correctly. 
You'll need to hand over some ID to receive a transponder at registration. Please return it promptly after racing and remember to collect your ID.

​Use zip ties to securely fasten the transponder ​at the bottom of either fork.

Cut off excess zip tie with cable cutters for neatness and to prevent interference with spokes.

Be careful not to loop the zip ties around a spoke

You may not get a time if the transponder ​is higher up the fork

You definitely won't get a time if it is attached to your bars
