Santangelo Borga tandem road bike Columbus MAX

[Stempie]

Here is my latest project. On my way from the Ukraine as we speak.

I wasn't necessary in the market for a replacement for my current Koga tandem, but after coming across this on Ebay I decided it was time for a change

It comes with all kinds of cool bits and pieces.

The brake assembly appears to be some of the first Formula have ever built, with carbon 4 bolt hubs and matching 2 piece discs. It has some sort of cable actuator that I have so far only been able to find on a Bianchi time trial bike.

The cranks are pantographed with B-space, but I am sure they are just relabeled. Can anyone ID these?

Here is a picture of the disc brake actuator on the Bianchi. Looks identical, the only difference being it is fitted directly to the caliper.

Very exciting looking machine. Will be following with interest.

Now that is cool, and tandem isn't bad either

Finally got some work done on the tandem. The most exciting thing was connecting the brake lever cable to the hydraulic converter. I wasn't sure what to expect seeing as it is 20+ years old and I am still not sure if I did it right, but it moves surprisingly smooth. Unfortunately no movement at the brake caliper though, so I will need to figure out how to bleed the brakes.

Here you can find a short movie of how the converter works: https://lfgss.microco.sm/api/v1/files/a ... 13f69f.mp4
