Remove Freehub Guidance

[Alan Farroll]

Hi,

I have a Giant Defy 5 (2013 Model) the weehels are Giant S-R2's (I think). I am servicing the rear hub and I want to remove the Freehub. I have tried a 10mm and 12mm Allen wrench but neither fits I am not sure an 11mm is available and don't want to buy one if it will not fit. How do i remove this please? I have attached a picture

Thank you Cyclops. 11mm is the only size allen key i do not have so will order one and use the 3/8th extension bar for now.
