I have a Zullo Track bike which i used to race, but dont want to take it out on my regular commute. So I have converted my old Giant ATX 780. This is what I did:

> Built a new wheel: Velocity Track hub with Velocity Aeroheat rims and DT champion spokes (260mm)
> Replaced the LX cranks with some Sugino Super Mighty's to get the right chain line.
> Got a frame-builder nearby to:
- respace the dropouts from 135 to 120;
- reshape the right chainstay to get the clearance for larger chainrings; and
- replace the vert dropouts with horizontal dropouts.
> Cleaned, etched and primed, and the painted with a can.

The attached photos show it with a 51T chainring - and there is good clearance with the stay. I am running an old Galli 44T by 15T until I can find suitably priced other stuff - hopefully at the bicycle recycler.

All in all, I am really happy with the way it turned out. It rides OK and will give a few more years of fun to a bike that was in need of a heap of money to replace old components.
