During the Derby City and Legacy nationals we will be trialing a new version of Race Manager that will allow for amateur class scoring via transponder. In addition to the Men, Women and Vet pro classes, transponders will also be required in the following classes:

SX Open

10 Cruiser

15-16 Girls Expert

9 Expert

16 Expert

Riders are welcomed to use their own transponders, purchase transponders or use loaners for the weekend. If you plan on racing in one of the classes listed above and you or your rider owns a transponder that has never been used at a national event, please email us your transponder details at timing@usabmx.com.

In classes using transponder scoring, the rider is solely responsible for the operation and proper mounting of their transponder. All riders in transponder-scored classes must scan and confirm rider details to be correct for that day's racing. USA BMX will provide several transponder checking stations where riders must check the operation of their transponder before entering the track for the day. If a transponder is found by the rider to be non-functional or have incorrect rider details, they must immediately report to registration for correction. Any rider who starts a race in a transponder scored class that has a non-functional transponder and has not utilized a checking station prior to entering the track will receive a DNS (Did Not Start) finish for that lap. Any rider who starts a race without a transponder will also receive a DNS for that lap.

If the transponder results of two or more riders are within 0.01 seconds or a rider’s transponder becomes detached from their bike during a race lap, the Head Official shall verify and (if necessary) correct that result using high speed photo finish. This action on the part of the Head Official shall not provide grounds for a protest and their decision is final.

Transponders should be fitted:

• on the left or right fork leg

• as far down the fork leg as possible but not on the drop out

• Mounting on the outside or inside of the forks is OK
