The seat post fit perfectly only the clamp is weak , otherwise the deal with Velobuil and Miracle was really good.
Season of Miacle is having great comunication i received the frame 7 days after buyng it, Season contacted me to tell me they have no more clear coat in 58 and he could send me a matt one without payng 40$ extra.
The build went really well i allready did 1000km with the bike and it ride beautifully .
The only problem i had was the carbon seat clamp to weak , the front derailler hanger got unglued from the frame when i adjusted the derailleur by hand without undoing eneugh the screw but the rivet are holding it .
And a clanking noise coming from the steering when i climbed out off the saddle, coming from the top bearing mooving a little bit Under pressure , i did the soda aluminium can trik to add a layer and supress the space , worked perfectly since no more noise.
I thing that s the only 3 thing you have to look at .
That really Worth it now i have a really reactive and fast 6.3kg bike , i m coming from canyon CF10 and Giant tcr composite , probably a little stiffer but less reactive and lively than the FM066SL a real winner at that price , here in France you can find it for retail Under brand name for 1490 Euros so 3 time the price i paid for it!!!
