Hi here to share my ecperience with a complete bike from tantan/seraph as I havent found any on this platform so far.
I bought this one:
https://www.seraphbikes.com/Carbon-Fiber-24-Speed-Aero-Road-Bike-TT-X71-Wheeltop-Di2-groupset-Carbon-Spoke-wheelset-With-700X30C-Tire-p6829310.htmldirectly from seraph site with paypal.
Communication was over whatsapp, quite good sometimes i had to ask multiple times when i asked multiple questions just one was answered but overall good.
First contact was 20.3. I wanted it with ltwoo but just went with regular wheeltop
order placet 26.3. The bike was in stock on the website but the wheelset still neded to be made (he said shipping in 15-25 days)
I got the QC Photos/shpping number on 28.4.
arrived at local carrier in germany on the 15.5. and at my door at 16.5.
So longer than expextet but still okish i guess.
Product came packed really nice no worries there, Casette not installed, handlebar dangling on the lines. (see pictures)
I build the bike up today so far really really impressed. I mean this bike is like 1000€ cheaper than when you build your bike up on your own out of china and the quality really blew me away. The only thing is that one bolt for the seatclamp was missing but i reacon i can find a replacement.
The only thing that worries me a bit are the weels. they are really true yes, but the spoke tension is quite uneven from my first check. I guess time will tell. the supplied Conti(probably fake idk) didnt seat right but i put on my STRs everything fine.
crankset/BB was pre greased.
I have some random parts that i cant identify really, i made a picture probably some of you know.
I got 2 nice carbon bottle cages and a plastic out front mount so that is fixed ig, but not carbon unfortunatly. (it was a problem the the carbon computer mount was to flexi, the plastic one definitly isnt.)
Gonna do a follow up post.
Ask you questions or what pictures you want.
Best regards from berlin
