Had a wee further dig and the sector and nex-gen rims seem to be the exact same part so seems likely the Whytes are too. Though I think Whyte went 28/32 while the others are 28/28. But, the Sectors have reviewed pretty well in a couple of places.
(plus, frankly the Whytes are the only ones that don’t look orrible, the sector and nex-gen share that hideous faux-woven graphic and “graphic design by an engineer” logo, the nex-gen gets a shiny logo like the Whytes but it’s lost with all the background, the whytes in the flesh are absolutely lovely with the shiny logo on plain carbon. )
