Just out of interest how does it differ from the DB, is the angles or tubing used?
Roberts produced three MTB frames that I know of - the Genesis, White Spider and the DOGS BOLX. Only the DB had a mono-stay and was very stiff as a result (on mine, you can see the rear stays flex slightly with V-brakes - not something I saw with the original cantis). I think the WS and DB shared Columbus Max downtubes - ovalized at each end but at 90 degrees to each other. The Genesis was cheaper but all were fillet brazed, and I remember being measured for my frame, so it's not a 16"or 18" etc, it's a 'mine'. Angles could be tweaked a bit for comfort, stability, etc according to the customer's choice. All I know is I find my limits well before the bike's!
Tubing mixes varied with vintage - some may have had some Tange, others Reynolds, some Columbus - as the various new tubesets became available. But this is only what I can remember from my morning in the shop all those years ago - you'd have to ask a real expert - or the Man Himself!
