SB5422
SB5422 is a very similar build to SB6398 (also within my Featured Frames). It is actually mistakenly stamped as SB4522, a mistake I investigated and proved in one of my blog posts. I’ve tweaked this build slightly with a Campagnolo freewheel, Regina SL chain, 2nd Gen Super Record Titanium BB and an SLG Turbo saddle.
