# 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.
