I was looking at DeDa Elementi Crononero Low Rider Tri Bar and cinelli dinamo drop bar, knowing the different between these 2 bars is one is easier for climbing and the number of positions I can hold the bar. Is there any way to make an easier choice between them? or this there an explanation to help me understand these 2 handlebars and make a firm choice? Apologise to everyone if you think you have wasted your time reading this

Those Deda bars are for time trialing. They're good for making your bike look cool and pretty much nothing else.

The Deda's (if they are the down sloping ones) really only offer one good hand position - bar ends or hoods (however you want to think of it) and only one brake access position. The flats position is compromised due to their downward slope. Yes, you can use that position sure but it is sub optimal and not designed for it. They also would suck for hill climbing as the hood position is too low. They are made for Tri athletes or TT's who get into an areo position and ride long distances that one way. Usually for Tri's they would be partnered with aero bars. If the bars did not slope like that they would be what are commonly referred to as bull horns. Ok as a bar, but more of an urban thing due to lack of hand positions for alternating over long distances.

The Cinelli's are a basic classic drop bar offering three clear hand positions (flats, hoods, drops) and two brake access options (hoods and drops). You go aero in the drops, climb on the hoods and rest on the flats or switch them all up when going long distance. People will of course have their own opinion as to which position they prefer for what and add more marginal hand position options as well but those are the basics.

If you are looking for a comfortable TT/bullhorn style bar: Zipp Vuka Alumina was my favorite but if you like the upsweep the Cinelli bars are great (formerly done with MASH SF but now on their own) I think also 3T did a nice looking one but I never was able to get my hands on it.

If you are looking for a drop bar: Zipp Service Course SL-70 Ergo would be my top choice as I have them on three bikes currently and probably will end up with them on four of them in the near future. Super comfortable flat top section with a nice transition to the hoods and a good compact drop. They also make a heavier version which is cheaper and one out of carbon which is not but not super duper light both are listed as 70-ergos. I am using a Cinelli bar which was slightly similar (flattened top section) but honestly I wish I had just gone for the Zipp bars to start but I thought "try something new, it looks similar enough, you want to save money right?".The only other bar I really want to try right now is the 3T Superghiaia when it comes out in aluminum but I may get the carbon version at some point if they don't. However I don't have a bike for them yet.

For Flat bars: Ergon grips, Ergon grips, Ergon grips! The bars don't so much matter to me as long as they have Ergon grips. However I do have an old set of Ritchey ForceLite bars, Thomson Ti bars and a Spank Oozy Vibrocore bar but the Thomson and Spank aren't on bikes yet as I am still gathering parts or just trying to make time for the build but I have Ergons for all.
