One of the cool things about the SRM Origin Carbon power meter is that you have your choice of spindle sizes. With the Origin, you can run either a 24 mm or a 30 mm spindle. This makes the power meter compatible with virtually any frame on the market. Well if you currently have a 30 mm spindle and want to swap it out for a 24 mm (or vice versa), look no further then this SRM Origin Replacement Spindle. It is available in both 24 mm and 30 mm sizes.
Please note that the SRM Look Ring Tool (sold by us separately) is needed to change out your spindle.
