The reason I went with peter/ carbonspeed, is the rim width is a more modern with 33+ outer width fit for tires of 30-32c (as long as your bike has plenty of tire clearance) These elite ones are 28mm outer width so typically optimized to use 25 or 26c tires. I wouldnt buy a new aero wheelset optimized for less than a 28c tire. Wider tire is supposedly faster up to 32c, and 32c feels like an all road bike to me. I am waiting on shipping so no experience riding them yet

i can recommend airwolf's T1000 (allegedly) cockpit for about 100 eur, on AliX. I bought 6, very happy. afaik they only one 1 such model on alix, you cant miss it.
dont buy airwolf frames though.

for wheels, agree w Ludo. you can message Peter from Xiamen carbon speed on whatsapp and ask him what he can do with your budget, it's enough for a really nice set of wheels with T800, good steel spokes (you can ask for pillar wing 20 if budget allows) and house hubs. Dont get the 100% T700 option, wont be as nice, it's worth spending a little bit extra (really not much).

I've been back through my Ali and I bought my Toseek integrated bars  in Dec 2020 so an older version that came in at about 350g.   So they were a previous version to the one being referenced but I can only speak for my experience with the brand, which on my sample of 2 has been good.

No experience with them, but I've bought 6 airworlf cockpits, they cost the same, they look similar, they allegedly include T1000, they are lighter so that gives credibility to the T1000 claim, and we all find them very stiff. I wouldn't buy a frame from them, but I really like their cockpits.
