Spoke Key Sizes

EKIMIKE

I need to buy a spoke key to true up my battered winter wheels. I don't know which spoke key sizing i need: 3.2mm; 3.3mm; or 3.5mm?

The wheels came on a Bianchi Via Nirone and are Ambrosio WS-23 rims on Miche hubs.

Can anyone help?

all three in one. very handy. dont economise on a spoke wrench if you dont want it to slip.

Yup, get a 3-way one like Park and use the tightest fitting for your spokes - I've found that not all nipples are the same size.
If using alloy nipples, get the Pedros ones which engage with 3 sides:
