I regularly swap from the 10mm rise to the 20mm rise Renthal Carbon bars. One is the Carbon Light 740 10mm and the other the Carbon DH model 780 20mm. The bike with the 780 has a 65HA vs 67HA on the 740 bar.
It takes seconds to adjust from bike to bike. I can’t say I can tell the 10mm bar rise difference between the bikes. The head angle makes more difference but the feeling of the change only lasts seconds.
The body adapts very quickly as soon as you get moving.
I think the new 35mm bars are 20mm wider in both versions for the same weight as the older models I have.
Is it an “upgrade” to go from the Alu versions to the Carbon versions? I did and I think the feel through the bars is just nicer on the Carbon versions.
