Your bars and stem look quite a bit lower on the Cinelli.
Just a guess but at least a couple inches, which is a big change. Drops also bring you down, as you mentioned.

In turn, that is moving more weight on your shoulders and neck. This will amplify all the bumps and jolts.
It also rotates your hips and that could be the reason, or one of the reasons, for your saddle discomfort.

In my experience, moving the saddle fore/aft/tilt even a few mm or a cm is the difference between pain and all-day comfort.

A suggestion:
Drop your saddle slightly to closer mimic the saddle/stem relationship you had on the Bianchi.
My guess is that you will feel a lot more comfortable, even in the drops.
If it works, get a stem with higher rise (like your Bianchi).

Without seeing, it's all a guess but that's the obvious difference between your two setups.

As for breaking your wrists, practice tuck n roll! Get your body used to falling a different way.
It's instinct and people often repeat the same fall and same injury on a bike. Get on the grass, start without your bike and tumble safely.
Get your body used to falling safely without your wrists taking the brunt!


The Cinelli looks fantastic, I like the half-taped bars too!
