One of the revolutionary things about the SRM Origin Carbon power meter is that it’s compatible with various spindle sizes. If you already own the Origin and want to move it to a different bike, the SRM Origin Replacement Spindle is the answer!
The Origin Replacement Spindle is available in both 24 mm and 30 mm diameters. In addition, the 30 mm Origin Spindle comes in both 134 mm or 138 mm lengths. The 134 mm fits most frames, while the 138 fits BB386 EVO frames. These different spindle sizes make the Origin compatible with virtually any frame on the market.
