I am planning to turn my old faithful do everything touring bike into a tracklocross. I am pretty confident I'll be able to fit 43mm tires into the frame but I'm not sure about the rims I've got.

The wheels I'll be using are the stock wheels off my cinelli Tipo pista so pretty standard 700c fixed/single speed deep aluminium rims. They obviously run 25-28mm normally (think they came with 28) and I've fitted 32mm to similar rims in th past.

So my question is can I achieve the big tires I want with my current rims or am I gonna have to buy different wheels?

TIA
