ELOS uses what's termed "oversize tubes". This means a 28.6mm top tube and seat tube, and a 31.75mm down tube. The chain stays were also ovalized 24mm. Because the tubes were larger diameter than "standard" sized tubes, which were 25.4mm top and 28.6mm down and seat tubes, along with 22.2mm chain stays, the ELOS tubes could be made thinner to save a little weight while not giving up any stiffness as compared to a "standard" set like SL.

Max on the other hand uses what would be termed XL OS tubes: 31.75 top and seat, and 35mm down tube. The chain stays are larger too. Basically, the Max tubes were both larger and as noted earlier, shaped more to resist deflection. Top of the heap for strong riders, but the larger tubes were heavier so only the strongest of riders typically chose it for their frames.
