My friend has a 26″ Saracen Myst DH bike. It was the last model prior to going 650b wheel size. It has a carbon rear triangle.

He has told me that there is ‘something missing’ from the rear axle. The rear axle pushes though from the NDS and is then secured by some sort of shaped nut to hold it in place. He seems to have lost this nut. Can anyone tell me the correct name for it and where i may be able to buy one from?

I’d contact Saracen either direct or through a dealer. They’ll know what part it needs.
