Review of Vello Sub Titan powered by the Slant community.
"the Vello Sub Titan uses particularly light, yet very robust titanium as the frame material. As a result, the minimum weight is only 24 kg (53 lb) and the maximum load capacity is stated as 210 kg (463 lb). The permanently installed luggage rack can accommodate two child seats and carry loads of up to 100 kg (220 lb)." according to NotebookCheck.
