The X68 IS a COUNTERFEIT frame. They don't put S-Works logos on which puts them in the darker shades of grey instead of dark counterfeit. Their frames/forks aren't manufactured by TanTan I think. At least I've got two X68 frames which are quite different in terms of quality.

Sorry but...You really don't know anything about law!
 ::)There is an important difference between:

a counterfeit → a copy intended to pass off as the genuine brand; Misuse of a trademark
For example, a frame bearing the Trek or Specialized logo when it was never manufactured by that brand.

A near-identical copy of a protected design
This can involve:
the frame design,
certain specific shapes,
patented elements,
characteristic decorations or colors.

an “open mold” → a generic frame legally manufactured without a copied brand. An open mold frame is not necessarily illegal as long as it does not reproduce

in this case, Specialized does not register the frame shape or even its name (SL8). only the logos specialized, S...and trademarks "sworks" "sworks tarmac sl8, roubaix, and so on are registered and can only be used and reproduced with the brand's permission. Therefore, the frame Tantan is not a counterfeit, simply because it only reproduces a form of frame that is not registered.

There were sl8 clone forks that exploded under riders a few months ago. There was someone on this thread with a rear triangle that made the bike unrideable.
And more performance, really? The new fake colnago weighs like 400g more than the original: how is that going to ride other than like dog $hit?

Please, read again. I never tell bike are more performant !
Bikes will always break, whether they're counterfeit, generic, or premium brands. I've owned loads of bikes and none of them had a problem... well, almost. I did have a Trek Fuel EX mountain bike whose seat stays cracked, even though the frame cost over €3,000 at the time. My personal conclusion is that these bikes aren't any less bad than others. Everyone is free to do as they please.

wow 53 pages on chinertown for a fake frame!

there is nothing chiner about this frame gentlemen! this is piracy. wonder why the mods aren't doing anything

Ce n'est pas un faux cadre, c'est un vrai cadre...
L'illégalité ne réside pas dans le cadre mais dans l'usage de la marque factor, qui est déposée.
Tu pourrais bien appliquer le logo Factor sur n'importe quel cadre que le résultat serait le même, usage d'un logo, ou d'une marque déposée sans autorisation de la dite marque.
C'est comme une paire de logo Enve sur une paire de roues qui n'est pas de la marque, c'est illégal.

Il est même possible d'acheter ce cadre sans logo...ce qui n'en fait pas une copie illégale !

This isn't a fake frame, it's a real one... The illegality lies not in the frame itself, but in the use of the Factor trademark, which is registered.

You could put the Factor logo on any frame and the result would be the same: unauthorized use of a logo or trademark.

It's like putting Enve logos on wheels that aren't from that brand; it's illegal.

It's even possible to buy this frame without the logo... which doesn't make it an illegal copy!

Personally, I only had minor issues: the stem cap was poorly finished, and the screw that holds the insert at the rear of the frame for the thru-axle was a bit of a problem.

With those two small issues fixed, the bike is perfect. Another 150km and 2500m of elevation gain this Sunday!

2500km since I've got it !

Il faut poncer l'intérieur du pivot pour qu'il soit rugueux. Tu peux en plus mettre un bout de papier de verre enroulé sur l'expandeur , ce qui renforcera l'adhérence.

ok but...no replica aren't lighter than original
V2 original weight about 820gr in 54, mine goes overs 1050 ! (and other goes same)
Original Fork about 350, mine about 400

J'ai rencontré le même problème (je l'avais d'ailleurs écrit un peu avant dans les pages du forum). Il faut effectivement soit un guide, soit beaucoup de chance pour réussir (une lampe aidera ! ). Donc rien d'impossible mais patience requise.
