Internal diameter of Mongoose please

[Wobba]

Need to know as I'm modding mine and need sizes. Seems smaller than my huge Oreca 2.5" one.

iirc mongoose has a 65mm external diameter (2 1/2 inch) so i guess minus prob 5mm so 60mm int diameter?

Mongoose is 2 1/4 = 57mm OD
I would imagine the I'D would be around 54 or 55mm
