It's not a good idea to use that DA2.
- The dropouts will be too short.
- You'll have to all but completely disassmeble it to make it ready for use on the track (remove derailleurs, brakes, shifters, etc...). Then you won't have a road TT bike.
- You cannot use a freewheel on the track as you will have no ability to brake with your legs.
You are better off buying a basic steel frame than spending the time, energy, and money converting that one.
