In my opinion, the real S-works tarmac SL7 is one of the most incredible and prettiest bike frames there is.
While searching for something similar I have realized that there are a dozen different copies with the same geometry but under different names and specifications.
The BXT 115 with a round seatpost, Velobuild 168, Trifox X18, TFSA JH-033 and probably a few more that I missed.
Most of them are marketed as T1000 carbon which I doubt and they are all quite heavy, some are on par with the original Specialized Tarmac SL7 Fact 10R.
But please post pictures of yours, weight (and spec) and please share your experience
Cheers!
