To add onto this, FSA has an acr cone spacer for the R5 which should fit the Soloist. Haven't had any luck finding it in stock however.spib wrote: ↑Fri Mar 24, 2023 8:17 pmOkay, I heard back from FSA and cervelo about a couple things.
Cervelo on whether the 14mm spacer is included in the stack measurement:Cervelo on using ACR internal routing:Neither bearing cap is included in the calculation of the stack height -- that top of the measurement is the top center of the head-tube.FSA on internal routing on the soloist:Hi again Spencer, unfortunately I really can't comment on Visions products, but you're right, you would need everything to be compatible with the 1-1/4" upper bearing on the Soloist.
With that said, if you are interested in converting your Soloist to internal cable routing, you can do that with a set of our bearing caps and spacers along with a new stem that are all designed for internal cable routing.
If you go to a certified Cervelo dealer, you can reference these parts that you'd need for the conversion:
BC-ST32 (Internal routing bearing top cap)
SK-032 (Internal routing spacers)
ST31/32 Stem (ST31[carbon], ST32[alloy]; stems for D-shaped steerer for internal routing)
Using those parts above you can achieve internally routed cabling with your Soloist, but this wouldn't be an integrated stem/bar set-up.So that means that the jumbo bikes are either using some kind of 3D printed or pre production option. I'm still curious as to whether the 1.5" spacer would work just as well, but definitely interested in a 3D printed version too. Just looking at the headset diagram it doesn't seem like you would need to change the headset itself out to run ACR.Thanks for contacting us! The first step would be to purchase one of our ACR headsets. You can use this tool to find ACR headsets compatible with the frame:

Atop the headset you’ll need an ACR cone spacer like this one:

but for the Soloist model. Those are in production now and we should see them in the next few months.
Hope this helps someone!
