your bike looks like a wc racer as it is.
Allison rode azonics risers I think, and they acctually had SACHS twisters and some xtr rear mech at some times.
She was probarly the only one riding risers at that time, don't really know why they just didn't flip the stem?
and it's also a bit interesting looking at F-series bikes from 2000 and after who have the stems on the + side insteed of downwards. This makes a F-series bike look like a pollished turd.
My point is don't get caught up in the idea of making an identical replica because they had various of bikes, I've even seen Allison on a Killer V with maguras and that strange black fork. Probarly somekind of test bike, looked ace. You have a great foundation, your bike must be rather light to!
