TriRig is finalizing a universal cover currently. That along with…Alpha One, Omegas, Styx, Flo 60/disc, and GP5000s/latex and whatever newer frame should be pretty competitive (I scooped up a new QR PR3 frame for $700).
Got a used scott plasma 5 with 11S sram red for 2500$, if you want a superbike for a low price just buy one used

The main reason of thinking about Cervelo is I know my fit exactly due to riding one for 4 years and every year getting a retul fit to continue to refine my position. I know frame size and etc. some measurements will change a hair due to going towards a high hand position I’m sure but there will be little guessing on my limits on reach/stack and etc. I know there may be better bikes and etc. I guess it’s tunnel vision, I’ve road Cervelo for years and never had any issues and I know my fit measurements
