It looks great, especially with those Collegiate/Suburban bars, Suntour shifters and new RD. Are they BMX or MTB brake levers?

Recently I used a similar set of bars on my 2003 C-Dale comfort bike (I hated the MTB type (nearly) straight bar). And at the same time I tossed the fat gel saddle and added a spare Brooks B-15 to see how it felt. With C-Dales smooth, fillet brazed look alike, tube joints, it sort of gives the same appearance of your SS.

Thanks for posting your conversion.
