SRM PM9 Origin Track Aluminum Power Meter

The SRM PM9 Origin Track Aluminum Power Meter adds another option for riders that want to take advantage of the best SRM has to offer. With the Origin Aluminum, you get the accuracy, consistency and durability SRM is known for, but at a price below that of the Track Carbon version.

In addition, if you’re looking to run shorter crank arm lengths, the Origin Aluminum has you covered! While the Carbon version has 170, 172.5 and 175 mm options, with the Aluminum you also have options of 160 and 165 mm. 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.

The SRM Track Aluminum Power Meter is available in either a standard or rechargeable battery and can be purchased as a power meter spider only, sans the LOOK crank arms.
