Can Rally Conversion Kits be Used on Vector 3 / 3s Pedals?
Rally RK, RS and XC pedals use the same spindle design as the Vector 3 and 3s pedals. This similarity allows the pedal bodies of the Vector 3 series and the Rally series to be interchangeable with each other. The non-sensing pedal spindles of the single-sided power meters differ in that they do not contain any electronics required for power measurement. As a result, non-sensing spindles will have a slightly shorter threaded section that threads into the crankarm, but this does not affect the compatibility with a sensing body.
NOTE: If you have the single-sided Rally or Vector system, the right pedal has no battery carriage and additional parts will be required if converting to a dual-sided system.
