The 9th generation SRM power meter uses a combination of angle and torque measurement. So it is has now a higher accuracy at a low cadence, also the usage of oval chain rings (Q-rings) is possible. Finally the cadence magnet is not necessary any more and pedal smoothness and L/R data are shown. Another upgrade is that the Gen9 power meter of SRM now also has Bluetooth LE (Bluetooth Smart) and so the usage of additional bike computers and Smartphone Apps is possible. The Origin Road Carbon is available with two different sets of Carbon cranks. SRM offers the Origin in several versions and the modular foundation brings a "build your own" experience to customers. Start with your crank arm length. Then choose your chainrings; the original SRM chain rings or the Carbon TI chain rings. The Origin PowerMeter lid, with a rechargeable port option, is interchangeable to match your chainring model. Then select your spindle type and length, 30mm and 24mm options.
