Front 20mm I weighed at 178g, rear I can't actually remember, but it was marketed as the lightest 150mm rear hub available. I do recall it being lighter than a Hope Pro 2 that I weighed, which is significantly lighter than the likes of King, Hadley, DT etc etc.
The only hubs I can think of that are lighter are the Tune King/Kong combo, but they are over $1000 for the hubs alone (using current exchange rates).
The Burg's arn't silly money thankfully. 48pt engagament so pickup is good & they are nice & quiet too.
Both of ours have been brilliant - can't recommend them enough. Disco Camo went down well with my girlfriend too
I had a pair of Tune XC hubs. They were great until the flanges cracked and the spokes started ripping out. When the rear went I had a long and anxious ride home on a progrssively disintegrating wheel.
