Thanks for the reply. I am back on it now after the excitement of the Lotus. So watch out for updates. Would be good to see your pics, particularly the Superlite. Is it still in original paint, as I stripped mine years ago but may try and recreate the original paint
That looks like a 1991 Super America as 92's had the square box section chain and seat stays. The Superlite was the same frame as the Super America but with a DX and XT mixed groupset whereas the Super America had all XT. The Super Evolution was the elevating chainstay version of the Super America but came with Scott-Pederson self energising brakes.
