# Shaft & Blade Sizing ## Outrigger Canoe ### Shaft For Outrigger Canoe, the power meter spigot is designed to fit a shaft with a **26.8mm** Internal Diameter. One Giant Leap have carbon shafts available for purchase with a **26.8mm** Internal Diameter. ### Blade If the blade fits *inside* the shaft, then the blade needs to fit into either: * a **26.8mm** ID shaft or * a **26.0mm** ID shaft (requires a 'spacer' One Giant Leap can supply on request) For example, a 26.8mm/26.0mm spacer is needed to get a Kialoa Ekahi blade to fit a 26.8mm ID shaft. If the blade fits *over* the shaft, then the blade socket needs to accept: * a **29.2mm** OD shaft (should you opt to use a One Giant Leap shaft). This means the blade socket ID needs to be around 29mm. For example, a Quickblade Kanaha blade has a socket with a 29mm ID and can readily accept a 29.2mm OD shaft. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
