My understanding is that that was the intention; if your favourite bike happens to have a long effective top tube/aggressive rider position, but you no longer have the flexibility/back health to maintain that position anymore, the Ortho Bars would help you convert it to a much more comfortable bike. However, on this particular bike that the Blue Lug guys are using, it doesn't work as well because the intended rider position is already very upright. Crust Bikes has a couple of videos on their channel where one rider is using them on a Rivendell Susie Longbolts, and the rider has *_much,_* much more room, as the Susie is much longer in the "top tube" and bars like the Ortho Bars are needed to correctly reach the front.
