SRM Origin Road Aluminum Power Meter

Precision Accuracy

SRM uses a 144 point calibration protocol against a known mass measured to the exact gram. With precise calibration and its Auto-Offset feature, the Origin is accurate to +/- 1.5%.

Compatibility and Convenience

The Origin offers near limitless compatibility with exchangeable 30 and 24 mm spindles, which means it can be used on virtually any frame on the market.

Battery Options

You can purchase the Origin with either SRM’s proprietary battery – which features 1,900 hours of battery life – or upgrade to a rechargeable battery for maximum convenience.

Options

Crank Arm Length:

• 160 mm | 165 mm | 170 mm | 172.5 mm | 175 mm

Chainrings:

If you would like to purchase this power meter without chainrings and use your own, please select one of the following options in the dropdown menu above:

• None – Shimano DA 9100 Lid. Select this option if you wish to use your own Shimano 110×4 asymmetric chainrings.
• None – Flat Lid. Select this option if you wish to use your own 110×4 asymmetric (non-Shimano chainrings).

If you would like to purchase the power meter with chainrings, available chainring options are:

• Miche Chainrings (50/34 | 52/36 | 53/39) – These are great chainrings at an affordable price. We highly recommend them.

Note – we also have Miche Campagnolo Chainrings available.

Spindle:

• 24 MM – For use with 24 mm Shimano bottom brackets.
• 30 MM – For use with 30 mm bottom brackets.

SRM PC8 Bundle:

• While not listed in the dropdown menus above, you can bundle the SRM Origin Power Meter with a SRM PC8 Bike Computer. When you do, you get $249 off the standard price of the PC8.

Compatibility

The SRM Origin comes with either a 30 mm or 24 mm spindle which means it is compatible with virtually any frame on the market. If you have any specific questions on compatibility, please contact us and we would be happy to help.
