I don't quite understand that. Surely all wheels are centred to the same centreline, that's what centred means. Some are wider for sure, but I'm not aware of any asymmetric wheels, or are there some?

I have 2 handmade wheels (1 Kinlin/1Reynolds) and I can say that there is about 0.5/1mm of difference in terms of centering. I know that on DA brakes I would probably not change the centering, but on Gravitas very close to the rim, I adjust the springnut each time I change the wheels, but yes, it's working without this operation.

I have bikes with DA 7900 brakes, KCNC C7, cantilever, SL Gravitas, Zero-G's and SL Negative G's. Swapping out wheelsets not being centered can indicate a dishing issue and I'd have that fixed regardless of the brakes being used so the wheel/tires track on the road correctly. In my experience, the single pivot Ciamillo brakes are less forgiving of dishing issues and rim widths and require a few minutes of tweaking when swapping rims out. But if you notice, even the dbl pivot brakes adjusted perfectly so the pads make contact to the rims evenly on one wheelset don't on another. If you are not overly fussy about your bikes setup (unlike me), dbl pivot brakesets typically have greater tolerances to rim width/dishing issues.

That's a lot of off-centering. You should just get your wheels re-dished and recentered proper.

Well, the green points are locking the junction between aluminum and carbon tubes. I trust Ted on the forces that are applying on a such part.
The prototype will be finally a BB30 in order to fit the bikes that Ted and me are currently riding. So it's compatible with all frames on the market except Trek Madone. But there will be shortly a BB24 available.
Ted has just told me that there was only the spider to machine and the to assemble to the rest of the crank. Then the prototype will be ready.... I hope this week !
The spider is easy to machine as it's just a double sided aluminum part and he has already machined one for the V1.

So it's been more than 9 weeks since pre-orders opened and the crank was to begin shipping in 6 weeks, and a prototype is not yet available. Does something not seem quite right here?
Maybe the ZeroG/Ciamillo crank should be called the
Godot?

What century are you living in? Your customers ARE your beta testers.

Got an idea, Everyone who wants the lightest, stiffest, best shifting crank out there send me $800 then when Ive got enough money I'll contact some guys i know who can design and make it. It may take them a few months but hey we dont mind a bit of a wait.
