Also does that work with the new Race cups? I am also running an extreme configuration and I switched from the F40 (way too wide for me) to the Race, and as far as I remember the F40 cup is aluminum vs the Race being plastic.
My engineers made a video of driving over the Race cup with a 4x4 to prove the toughness of the material. That was just for fun - the real testing is a bit more involved and structured. Yes, the Race cup is fine in the extreme positions.
Another question, is there any way to reverse the aerobar bracket attachement? That way instead of relying on just one set of bolts it would overlap on two sets. From what I see it would theoretically work, but then the tilting would be limited and it might not be recommended.
The tilt wouldn't work at all unless you modified the spacers. Which is, of course, not recommended and would void the warranty
Lastly, do you have a readable chart of all the possible configurations with both the 70 and 100mm Aeria Ultimate stems? I find Profile Design website documentation pretty poor, especially when comparing with TriRig Alpha X awesome configurator...
The site is pretty poor for fit info, slowly improving that. You'll learn more from the fit guide I wrote for Wilier
although it's not that helpful for other bikes. If you read the instructions in that document you will be able to use the tables below. With the exception that the AU tables are based on cockpit XY - the metrics from frame XY to pad XY (rear, incl cushion). So if you have a target Pad XY and and known Frame XY you can work out the Cockpit XY.
Static XY charts are pretty limiting for dealing with tilt. Tririg calculator is really good but the Y gets thrown out as soon as you tilt.
