These are Novatec without any branding in polished silver or glossy black. Novatec themselves have styled to look like the hub shell from older Campagnolo hubs so these suit older bikes too.
OLD for the front is 100mm and OLD for the rear is 130mm.
The front hub is the A171. The Shimano rear is F172 and the Campagnolo rear is F272.
The 24H front can be laced radially.
24H, 28H, 32H, 36H front hubs and 24H, 28H, 32H, 36H hubs are available.
The front hub weighs 116g, the Shimano rear 271g and the Campagnolo rear 263g. Skewers are included. Light weight and durable hubs with cartridge bearings.
The bearings seem well sealed and big 4 bearing in the rear hub and 2 in the front. There are two freehub body options. Shimano 184.108.40.206 speed (F172) or Campagnolo 9.10.11 speed (F272)
Hub dimenions are
Front Left PCD=38mm
Front right PCD =38mm
Flange to centre = 34mm
Rear left PCD =49mm
Rear right PCD =49mm
Rear left flange to centre =37mm
rear right flange to centre =18 mm
There is a small difference in flange to centre distance for the Campag and Shimano variants but it make little to no difference to the spoke lengths so I am not quoting it.
