Rear wheel offset??
 

Evening all. Hope everyone is well. I have a dilemma. I�ve stripped the rear wheel to fit excel hubs and being the first time I�ve done this I haven�t noted down the offset of the wheel!! Wat a pilock!! I can replace the rim and measure then but it would save me a lot of time and the ball ache of somebody on here happens to know the offset? If there is one, I�m pretty such it will be central but not 100%. Any help greatly appreciated. Cheers all.
