Derby Worx Pro BSA Grooved Axles
These are official BSA Pinewood Derby axles that have been machined, grooved and polished to give you an extra fast car. The four grooves around the axle shaft serve two purposes: 1) They create less surface contact between the axle and wheel bore. 2) They create graphite reservoirs to store graphite for better lubrication.
Most tests confirm that properly prepared grooved axles are the fastest BSA axles available.
These axles are legal for most BSA pack rules. You can use these axles as is, or fine polish them with one of our axle polishing kits.
