I completed my build Thursday (the same day my frameset arrived).
I had all of my build components on hand and was ready. No issues at all, I purchased this frame from another vendor on Ali, but its identical to the Airwolf YFR068/Cervelo Aspero 5. Ordered mid-June, shipped on 7/15, rec'd 7/18.
A few notes, just like everyone else -
The headset bearings and compression ring are different than Cervelo, but I found the quality of my bearings to be good. I chose to go with the SL7 split ring.
The through axle thread on frame is different than Cervelo, since the thread is an insert on the frame vs an independent nut.
The Rear derailleur hanger is different.
This frame lacks bottle cage threads on the downside of downtube.
This frame lacks frame protection on the downtube, though I had OE Cervelo pieces ready and they are self-adhesive.
The remainder of the frame is a 1:1 clone with Cervelo Aspero 5, all the way down to the paint.
I used full Sram Red AXS 1x XPLR and Zipp 303 firecrest wheels, so I can't comment on the FD. I removed the FD Hanger and replaced it with the Cervelo blanking plate. The routing of the two brake hoses was remarkably easy. I thought the idea of wide BB might be an issue for me, since Red does not come aftermarket with the wide spindle. I live in flat, flat Florida, so the idea of a larger chainring was kind of appealing...but I am a spinner, not a grinder. I went with a 42T ring on the standard width spindle. There ARE some OE SRAM Red Wide offerings but they are very rare and hard to come by, I even confirmed this with SRAM Support. My setup is NOT wide, and I have zero issues. I am running a 42T 1X ring and the 3.5mm spacer on the drive side of the BB. I'd be reluctant to go larger and for me, personally, its not needed.
So far, two rides logged (30 and 25 miles) - nothing significant to report, other than the standard re-tightening of things after the first ride.
Are you sure that you don´t have any play on the headset?
As far as I remember, original bearings have a 0,5mm bigger ID than the SL7 compression ring.
I think that you should have installed SL7 bearings together with the SL7 compression ring, which have a ID that matches compression ring.
As I noted before on this thread, mech hanger is also the same as the SL7.
About crank axle lenght. I have a RED-QUARQ crankset, normal road widht. With double ring 34-50, the gap from inner ring to the chaninstay is minimal, but I didn´t have any rubbing problem during more than 4.000 kms.
