Iam using some 165mm DuraAce cranks with a 130mm chainring right now. When I get a new track wheel and sealed BB I was thinking about switching to the 144mmBCD Sugino cranks I have. Whats the advantage? PRobably gonna get a Salsa track ring if I do switch.

Thanks

It's the standard track BCD, so ...Humma Hah

... you're certain to be able to get track chainrings (for 1/8" wide chain)in that size.

An earlier track BCD was even larger, about 150 mm. Most ders use smaller to allow small chainrings to be accomodated. For those, you're more likely to find the narrower chainrings used with der chain, which, the truth be known, will work fine.
Sounds logical...but.....Trevo

I have a pair of Sugino 144mm bcd cranks but they have two ridges for chainrings, cause when I got them they had two rings.

But if theres no advantage or disadvantage between 130mm and 144mm cranks, Ill stick with my old DuraAce 130mm cranks

Campy cranks of the Nuovo Record & Super Record era were 144 BCD as well. Track cranks -- maybe because there wasn't any point once road & track diverged into 3/32 & 1/8 standards -- never followed the shift to a smaller BCD.

Dunno...
