Re: Seraph Bikes Superlight 836g X68 - Alternative to SL8 Fakes? My bike is out of paint as of today, so figure around a little over a month allowing for the holiday break.
From the video the paint looks great and bb and disc mounts seem nicely faced.

My Seraph/ TanTan TT X 68 Build - Size 54 - Matte Black

6.94kg - $2900ish all in. Weight is plus or minus 50gwith grease, and misc hardware not accounted for.
I acquired most of these parts used over the course of 4-5 months, via ebay and facebook. I learned about most of the build options, not named shimano, from this site or via youtube (GC Performance, Pat Lino, China Cycling, etc...). I also built this bike by myself, first time ever doing a frame-up build, and used GC's SL8 bike build and his other videos.

Hey y'all, long term review here. I built the bike in January 2025, rode it on the trainer for about a month, and have ridden it outside 3-4 times a week since mid February. I have raced it once. I've got somewhere close to 500 miles on it at this point, maybe more.

Frame: it works, but cant speak to how it compares to other disc brake bikes. I do feel as though it is responsive to putting power down, but maybe not super snappy and that could be several other factors. My previous cervelo r3 rim brake was extremely snappy, but I was also very aggressive when riding that thing. The only "issue" I've had is with the headset cover deal rubbing on the frame itself, instead of floating a .5mm over it. Could be my fault when I built the bike, but going to chalk it up to the part being slightly off. For my first disc brake bike, I have really enjoyed riding it and I'm looking forward to going full weight weenie with it over the next year. I would highly recommend this frame for anyone going the china frame route.

Bars: I went with the 120/38 bars. The bars appear to be exact copies of the specialized bars. They are quite comfortable and have a large aero foil shape to them. I'm not entirely sure where they measure the stem, but this "120" stem has the same length as a 110 stem on another set of bars. I haven't noticed any serious deflection when sprinting, but I'm around 67kg and doing 1200 watt sprints. I don't like the computer mount that's included because it doesn't lock into the handle bar like a traditional 2 bolt under stem mount does. It gets the job done, but I'll be upgrading in the future.

Wheels: The CRW's are fantastic. Aero and lightweight. Seating tires is no issue.

Groupset: its ultegra di2, it works, nothing more to say. the aliexpress cassette works fine, and is only slightly less smooth than a shimano cassette.
