Thanks but this is the original manual instruction! 

Hi
3rd ride with Taiwanesen frame, 260km overall.
The frame simply “sails”, from 30km/h you can check this very easily.
I have set the presure at 3.8psi front and 3.9 rear (internal rim width 23mm) and this makes the bike very comfortable.
I do not know how to objectively assess the fork and bottom bracket stiffness, apart from during some sprints. Any ideas ?

I recommend putting this somewhere else, like I said before. This is not the same bike or frame.

Instead of acting as a moderator, please, buy a frame, mount components, ride and test it, post some photos and share your feedback.
The frame are the same, TanTan has just changed the headset, is it so difficult to understand ?

First decent workout with the fake SL8 from Taiwaneisen.
My weight is 65kg and FTP at 220watt. Wheels Yoeleo 50mm, tubeless 28mm, 4bar.
- the riding is “smooth”: after 35km/h you can easily observe the bike “sailing”, it keeps the speed with minimum power.
This is even more visible when you ride into a group of cyclists at 35km/h or more or when you follow the draft of a car passing you
- the frame is quite stiff expecially in the seatpost area: you can clearly feel in the back while the fork and the front part of the frame is quite comfortable
- I was worried about the stiffness of the fork as it weights even less than the original. I tested in a 3km discend and it is good

So far so good

Hi all,
How the hell do you adjust the saddle inclination on this seat tube when the saddle does not have the hole ?
I cannot strenghthen the anterior bolt.
This kind of seatpost is the same on TanTan and Taiwaneisen and identical to SL8.
Thanks!

For the sake of clarity and for the benefit of our discussions, let me share the reasons that lead me to buy a counterfeit - despite I was not and I am not in favor of this - are:

- weight: the frame weights only 835gr size56, seat post (long) is 173gr and fork is 312gr (uncut).
To be honest, the weight of the fork does not make me so confident (even lighter than the original) but I will try step by step, testing on gravel roads at low speed at the beginning and then on faster descends.
There are very few chinese frames with these weights at 600/700usd.

- the frame/fork shape: it is extremely similar to the original one and this grants that the great aerodynamic features - on the chart and so well advertised from Specialized - are "scientifically" proven or at least comparable to the original frame.
Chinese frames "no counterfeit" do not have this kind of studies/test behind.

Hi,
Almost completed my SL8 from Taian Eisen.
Size 56, 6.8Kg without chain, handlebar tape and pedals.
I have not ridden it so far.
It’s not Seraph/TanTan, do you want to open a separate topic ?
Ciao
