I agree with Eric and guy about alternatives. If one reason to have the square tube ends is for chainring clearance I might suggest extending the rocker's contact point "up" the tube, so the tube could remain round and the structure that passes by the chain ring can still be flat.

Not asked about but- The rocker's pinch bolt might be relocated to the 3 or 4 o'clock position to avoid the brazed/welded tube area. This change would free up the rocker's 9-12 o'clock section for an alternative tube contact. I find it easier to try to keep different aspects separate if I am still "prototyping". Andy
