A bit more of ride reviews. I rode about 200 km with the frame now. It feels really excellent and as I said I still have a Tarmac SL7 and they feel the same. I would even say the Seraph feels more planted on the road and is a bit stiffer but yes still comfortable.

Aerowise I cant tell the differences between the two, the speeds are the same. Until now I dont have anything negative to say.

ah maybe the only thing is that I cant see how the frame should be compatible with 140mm front discs. It is the same system as the SL8 has so without another adapter, which is not included, I cant see how 140mm discs should fit. For me that I was using 140mm rotors on my 4 (!) wheelsets it is a bit of a hassle but in the end only 2 minutes of work.

Ah and yes the bottom spacer of the steering tube needs to be sanded down or cut in order to not make it rub on the frame. Seraph could have payed a bit more attention to that but its also no big deal. Some could even buy the geniuine SL8 spacers I think.

I just finished building up my bike, and overall, everything came together smoothly.

The build is full Ultegra Di2 11-speed, with a Dura-Ace 11-28 cassette and 53/36 chainrings. I'm running a C-Bear bottom bracket, XTR rotor up front, and a Galfer rotor in the rear. The cockpit features a 100x380mm integrated handlebar paired with a MagCAD 3D-printed Garmin mount. Out back, I’ve got some budget-friendly Chinese oversized pulley wheels, and the wheelset is a Fastop Wave 45/50mm — wrapped in 25mm Continental GP5000 tires with latex tubes. Saddle is a very light (75 gr as far as I remember) Aliexpress saddle which I used hassle free already on my other bikes for years.

Power is tracked with Favero Assioma pedals. As it stands, the total weight is 6.65 kg. Swapping to my climbing wheels and a SRAM Red cassette should bring it right down to 6.5 kg flat.

The build process was straightforward — everything lined up nicely, with properly faced surfaces and a smoothly spinning bottom bracket. The only small issue was the lowest headset spacer slightly contacting the frame, but a bit of sanding sorted that out easily.

I just got back from a 30 km shakedown ride, and honestly, it feels nearly identical to my Tarmac SL7 — which is a compliment in itself. It’s responsive, solid, and confidence-inspiring, with no noticeable difference in ride quality.

I will put S-Works stickers on it.

I would like to try 165mm cranks and was wondering what the go to chinese crankset is for a 24mm spindle and BSA bb bike.

Shouldn weight a ton, shouldnt cost to much and doesnt need to be carbon at all.

I would prefer compatibility with shimano chainrings but it is no must.

Can you give me some suggestions.

I ordered the same day as you (13.03.25), and also was notified today that my frame was shipped out. Did they send you a photo of your order as well? In the photo they sent me, the seatpost looks a bit short. I hope they didn't send the short version (I ordered frame size 56). Also the frame looks rather black matte, although I ordered "UD matte", however that wouldn't be a dealbreaker...

No foto, they just asked me if the shipping adress was correct.

Very good news from my side. The frame was send out today. I excpect 3 weeks to get it.

I also asked that if the limiting part is the painting if they could send me the raw frame in the case its ok to ride. I dont care at all about the colour.

I mean yes. As I said I paye on march 13th and a few days ago she told me frame will be send between 12th to 18th April. Lets hope.

Was the surface preparation from the factory good? Bottom bracket and brake mounts?

yes it was literally perfect and on par if not better than on my geniune s works sl7
