As indicated earlier in the build log, I was intending to try out the VumaChrono crank after the PowerArm SL-Rotor Qrings. I now have two medium distance rides on the latter, with rotor setting on #2 position which caters better for a higher cadence style and I do like the feel of the PowerArm-Qring #2 setting combo both on the climbs and flat.
The VumaChrono will certainly have a high benchmark to beat when I try it out this weekend! It could well be a battle between round vs oval chain rings rather than mere aerodynamics.

As an initial feedback, the KMC 10XL chain shifts quite smoothly with the VumaChrono-Di2 setup.
