Bikes: too many of all kinds
The forum here often says, stick to the same frame size as you use on the road. Not bad advice, but there is one thing missing here. Handlebars.
Road handlebars can be pretty tight, while track handlebars can be pretty open.
Just comparing a pair of Dieda road/track handlebars, the reach changes from 75mm to 110mm, and drop from 130mm to 173mm.
You may be fine on a 54cm road bike, but if you go to a 54cm track bike with track drops, you are going to be really stretched out. Of course you can always swap the bars out.
Food for thought….
