SRM Origin Road and MTB Power Meters are highly customizable. In addition to different SRM lids and spindle sizes, you can order your power meter with different SRM crank arms. They range from lightweight and more expensive to heavier and more affordable. Please see the options below:
SRM LOOK Carbon Crank Arms
The SRM LOOK Carbon Crank Arms are the lightest and stiffest crank arms you can buy for the SRM Origin. They feature Trilobe pedal inserts and function in three lengths (170, 172.5 and 175 mm) simply by rotating the pedal inserts.
- Price: $800
- Material: Carbon fiber
- Weight: 260 grams
- Sizes: 170 | 172.5 | 175 mm
SRM Composite Crank Arms
The SRM Composite Crank Arms are made from a blend of carbon fiber and aluminum. This makes them strong and lightweight, but they are a bit heavier than the all carbon LOOK arms above.
- Price: $500

- Weight: 328 grams (172.5 mm)
- Sizes: 150 mm | 155 mm | 160 mm | 165 mm | 170 mm | 172.5 mm | 175 mm
SRM Aluminum Crank Arms
The SRM Aluminum Crank Arms are the most affordable crank arms for your SRM Origin power meter. The crank arms weigh 436 grams (172.5 mm) for the set and are available in sizes ranging from 160 mm to 175 mm.
- Price: $300

Please note, SRM also offers a THM Carbon crank arm for the Origin power meters. Unfortunately, due to very long wait times (often in excess of 6 months), this is not a product we are currently stocking.
