SRM PM7 Origin Carbon Power Crank

SRM has taken power measurement to the next level with its SRM PM7 Origin Road Carbon power meter. Like all SRM power meters, the Origin features SRM’s 144 point calibration protocol, resulting in unmatched accuracy and consistency. However, for the first time, the SRM Origin power meter uses a LOOK carbon crank arm which offers superior stiffness to weight ratio. In fact, the SRM Origin weighs close to just 600 grams when ordered with the LOOK Carbon crank arms!

In addition, the LOOK crank arm features Trilobe Technology, which allows the crank arm to function in three lengths, 170 mm, 172.5 mm and 175 mm, simply by rotating the Trilobe pedal inserts. The Origin also offers near limitless compatibility with exchangeable 30 and 24 mm spindles, which means it can be used on virtually any frame on the market.
