Track Cycling Instrumented Aero Cranks
After previous success with supplying instrumented cranks in the run up to London 2012, bf1systems were approached to co-develop a set of highly aerodynamic, instrumented cranks for use in the velodrome for the 2016 Olympic Games.
Working very closely with a research organisation, bf1systems have taken the wind tunnel developed space envelope and turned these into a set of instrumented cranks, strong enough to be used by the world’s top cyclists, whilst also providing highly accurate and repeatable data on the torque and force being applied to each crank arm.
These force measurement cranks were designed from the ground-up as cranks which were to be instrumented, and had to survive the highest loads seen anywhere in cycling, during the standing start of a velodrome race.
Each crank is capable of measuring the torque and force applied to it, along with its position, and transmits this wirelessly at 192Hz to the receiver mounted on the bike.
An internally mounted battery powers each crank, providing approximately 7 hours of continual use.
Status LEDs on the cranks provide the user with information on the current status of each crank arm.
