Bicycle power meters

FSA's MTB PowerBox carbon cranks use the P2M convertible spider design for multiple derailleur options. The FSA crank arms and BB392EVO axle combine to create a stiff, reliable and extremely versatile power meter crank, available in dual or single derailleur configurations. Bluetooth (included) Thanks to this update, your FSA PowerBox can transmit data via Bluetooth Low Energy (BLE or Bluetooth Smart) to your cycling computer. Balance left/right (included) The left/right balance shows the percentage each leg contributes to your overall performance. (power on the left = pressure on the left pedal + pull on the right pedal; power on the right = pressure on the right pedal + pull on the left pedal). Innovation of pedal flow Pedal smoothness is an advanced metric for riders looking to optimize their pedaling. It shows you how evenly the power is applied throughout the entire 360 ​​degree rotation of the pedal. FSA PowerBox power meters collect data for both legs together. Please note that the transfer of this data to your cycle computer is only possible via ANT+.  Features Convertible spider design for different derailleur and chainring configurations Hollow carbon composite arms with UD treatment BB392EVO 30mm AL 7050 alloy spindle fits any MTB frame (BBs are purchased separately) AL7075 100% CNC converters Thin tooth design for maximum chain grip Optimized for 11 and 12 speed system Specifications Type: Powermeters Technology: BB392, Hollow Carbon, Megatooth, Modular, No  Disciplína: MTB  Series: POWERBOX Farba : Neutrálna  Compatibility: BB392 Drive compatibility: Shimano10/11S, Sram10/11S  Materiál: karbón
