They are road cranks 7600 are completely different track cranks which are v nice
The chainline on the double road cranks (7400) will be too far outside for a normal track hub on the outer ring and too far inside on the front one ring
You can but surly fixed/free hubs with chain lines to match road cranks, but they are wider than track hubs and fit wider road dropouts, such as road frames & road frames converted to ss… not track frames
You can use a shorter bb to bring the cranks inwards to match a track hub chainline but you may find bits of the crank foul the frame
