Help me build my "Bertoni Crono"

Hello to all,
I was fortunate enough to be the recipient of a "Bertoni Crono" from member "Straightblock".
It will not undergo a full but a partial restoration.
In my opinion, a touch up of the paint will make it very presentable/rideable and more enjoyable for me to use. After I received it I checked on the web for Bertoni Crono and found one that was owned by member Bianchi Girl....unfortuantly she has passed it on to someone else and is no longer the owner.
In the next few months, I will address the paint and start my search for components that are appropriate for the build, and wanted to bring those interested along for the "ride".
I know that I will need the help and knowledge of members here for pointers and advice....I am looking forward to doing justice to the Marque.
Thanks again to member "straightblock".
Best, Ben

At home in Los Angeles...as received

Decals and a few areas of weak paint

Sorry, can't help you with the wheels.
But I do have a corncob freewheel (though not Campy)
Never seen that chainring in the flesh, either.

I had no idea anyone would rebuild and ride such a bike, it seems so ridiculously impractical! Like a 6-wheeled Tyrrell in bicycle form.

Hats off to you, seriously. I'm curious to see how it turns out.

Most likely Campagnolo, either SR or a newer style groupset that is possibly more AERO. I will post options after some deep cleaning and decision about which color of the repop decals.
They are currently black or dark blue but I have a nice red saddle so I might not go the original route but apply some red decals or Gold ones.
Best, Ben

I may have a 650c rim gathering dust. I'm also on the left coast but still shipping rims is a pain.

The way the bars are setup in the promo, this geo would actually work for me. Though, with that huge gearing, not sure where I could ride it. Might have to push it up a couple hills so I could get to the trail.

I'm one huge, short hill away from a fairly flat and long trail (the Interurban) where I could ride for several miles. That bike would be the lightest I've ever ridden, so I might surprise myself. It would be serious fun.

I have some used Specialized 21c, 115psi gumwall clinchers if interested.

Be sure to add to the Gotta Bertoni thread at some point. Cheers.

Cleaning and repacking the BB and HS tomorrow.. a little wax because the paint is crazing a bit.
Fun times and a good diversion given the circumstances we are now going through.

Nifty the way the chainring fits around the spider on these.

They were not impractical. (Aside from the disc on front which would make steering hazardous, except in very calm air.) Nor were they even particularly uncomfortable. It was the UCI's banning them from competition that ended their production. Take a look at the Vintage TT thread for others..

Nice project. ,Eric

Hi Miguel,
Thanks for the offer but I have some bars already, and using those would strain my already old back even more .
In good faith the next time I see you I will contribute to your calorie count by buying you a cheeseburger....DBL DBL with cheese right?
Best, Ben

Yes, the paint seems alright but the rear stays are the worst...there is crazing of the clear but I think a good polish and wax will make the surface more than acceptable...at least to me.
I'll Know more later and post the outcome.
Best, Ben

I love those curved tubes. What year was this frame from approximately? Are you going to modernize the drivetrain or keep it old school with downtube shifters and the like?

ICM,
I like the simplicity of the design too.
I think it was built in the '90s, at one time it was set up with bar ends as can be seen....my plan is to go old school as much as possible but I also like the newer campy stuff (more AERO), realizing that I can't afford to go full restoration and source all of the almost unobtainium parts necessary for that.
I want it as period-correct as possible and like the fact that it will have "some" patina so if it gets a little more I will not go nuts about it.
Soaking a decal with Googone as we speak...hope it works.
Ben

Built in the 90's is good! That means 130mm spacing and most likely Ergo STI shifting to begin with. So that opens up all kinds of possibilities to mix and match in modern components.

Well, I got this far and it appears they were clear coated.

not too much paint loss, I di duse a hairdryer to help remove the adhesive.

Still soaking the decals with GG and decided to move on to the seatpost.
I wanted to do a "light" polish and paint and then try a seat on the frame to check for color....red, black?

the before A little rough and I want a little more shine but not too much

The after with the paint applied...it is a bit shinier than in the photo. The flutes still require a touch-up!

Well, I could not resist trying out a saddle on the seat post.
I am still trying to find my other option but things around here are making me quite busy.

resisting the need to put it on the bike...maybe tomorrow!
