I’ve been researching. A Nitto stem won't accept the 26.4 Cinelli bars so I’d need bars and stem. The old Cinellis are so beautiful.... I got barcons etc but haven’t put them on. Campagnolo down tube shifters. Nice until I crash reaching for them. I’m torn between keeping the Holdsworthy original or ridable. Its a hand built 531 frame. Hard to improve on that at some level. I guess the frame is the soul of the bike so even with new bars and shifters it’s still the same. Sort of. Still a new something is tempting. I really appreciate all your input. The simple obvious expensive solution is to buy another bike and ride twice as much. Thanks. Dave
