Inaugural ride
The inaugural ride of the De Bernardi! Thanks everybody for walking me through this project. I hope it's not too much of an abomination that I put mustache bars instead of drop bars on it (or the mish-mash of new and vintage parts). The wackiest is the mismatched Veloce/Potenza brakes. I'm really digging it though! It rides so smooth and fast. The coolest part is indexing actually works, which totally proves what Doc/ rccardr and others have said about Shimano's ratios being unchanged, aside from the Dura Ace 740x and I think a couple others. I was planning to just do friction, but I got a Shimano Sora 8-speed indexed lever on a whim, so it's got the new lever, a new Shimano HyperGlide 8-speed cassette, and the '86 RD-6208 derailleur, and it's as crisp as potato chips. I never would've expected that.
The Paul Component brakes were a last-minute splurge to deal with brake sponginess. Not sure if it was those, or the Jagwire compressionless brake housing, or maybe both together, but the braking is rock-solid now.
What a delight overall. Very happy with it. Thanks again to rccardr for the really beautiful frame and all the help.

It's a good question about the handlebars with the long stem. I rather blindly chose the longest stem just because I figured I would need the length to offset the sweep back of the mustache bars.
I haven't ridden drop bars since my teen years. That was all I rode on my first Schwinn "ten speed" back in the 80s, then rode a mountain bike flatbar for about 12 years on my commuter bike until I started experiencing wrist pain. A web search in the early 2000s suggested I try mustache bars and it truly eliminated the pain, so it's been my default bar since then. I'm definitely not wedded to them, though, and I'm tempted to try putting a dropbar on here try see how it feels. It would be neat to ride one again after all this time. That will probably be my next project in a year or two on this.
As far as turning, I haven't used it on any windy downhills so it's hard to say. So far it's just been beach bike path, which is fairly straight. It would be interesting to do a side-by-side comparison. It does make me wonder if it would feel different/better--maybe a frame like this is optimized for narrower bars?
