it sounds like these frames are flying off the shelves. I spoke with a chinese seller saying that chinese factories aren't focused on bikes like the pinarello X or BMC roadmachines because the chinese population is young and wants to ride the bikes from the TDF.
Point being, pretty sure that for those buying these SL8 clones, your money is competing with chinese money, so the whole planet wants that frame. Well done specialized 
One of the sellers I spoke to yesterday, as I mentioned, said the wait time for an SL8 is around 3–4 months—but he could get me a Dogma F in just 1–2 months.
I also asked about the Scott Addict RC Pro, and he mentioned that the wait would be even longer, since it's not a particularly popular model and isn’t held in stock. It would have to be made and added to the production queue along with the SL8s.
So yes, it seems like everyone is going crazy for the SL8s right now!
I also spoke with another seller—Cherry, I think, from Champion Bicycle or something similar—who said they aren't affected by the long wait times and claimed their frames are high quality. But let’s be honest, they all claim that!
I'm just happy to be back on track with Tan Tan, but I’m taking their timeline with a pinch of salt. Some buyers are still waiting for delivery, but these delays will be out of Tan Tan’s control. Hopefully, they can stick to the 20–25 day production time they’re quoting. It’s also great to hear about other people’s experiences with Tan Tan.
And yes, I am putting Spec decals on the frame—some may not agree, but I’ve got a real SL8, so that’s my excuse! I'm going for matte black decals over a gloss UD carbon frame. These are from Speedy Decals, although I recently found out I can get decals from a Specialized-approved painter in the UK for half the price—so I’ve ordered a set to compare quality.
