So I pulled the trigger on this frame yesterday - with a couple of unknowns. After coupons and discounts, I pair $604 US all in. The deal seemed too good not to bite.
https://www.dhgate.com/product/2020-new-seraph-per-sell-carbon-fiber-t700/507611131.htmlThe frame looks to be an update to the FM8 frame, with slightly smaller shock mounting (190-200), and asymmetrical chainstays.
The frame geometry charts dont make much sense to me. The geo table claims a 65.5 HTA, yet one of the diagrams shows 66.5 HTA. The wheelbase seems a bit short as well.
Looking at the TanTan website, they show the following frame, but dont have a model number. This frame looks identical to the new FM10 in pictures, however it claims to use a smaller still shock (185x55). Its geometry seems a bit more believable.

With the current situation in china, theyre not answering emails, nor do I expect the frame to ship any time soon. Thats fine, because my current bike (FS27) is doing just fine. I've amassed enough spare parts to build N+1, so Ill be keep the FS27 set up an as xc oriented 29er, and the FM10 will become my new 27.5+ trail bike.
I ordered up a new Manitou Mcleod shock in 200x56 size. If the DH Gate listing geo is correct, thats fine. If the TanTan website geo is more accurate, even better due to the longer TT and wheelbase, so long as I can fit the shock in there. It appears they kept the shock flip chip, so that should take up 10mm of shock, and hopefully I can just hyper extend the additional 5mm. The extra height would be somewhat welcome with the 27.5+ tires. If not, then Ill just add travel spacers to reduce the shock to 195x51, and hope for 140mm travel. I plan to stretch my manitou magnum fork to 150mm by doing an internal mod to reduce the top out spacer (as per a famous manitou tech from new zealand).
Now I ordered the frame in matte black. My current FS27 looks flawless in matte black, but a buddy ordered the same frame from an ebay seller, and his shows all sorts of casting flash and layup imperfections. Since this was purchased from DH gate, I'm worried about the same visual imperfections. If that's the case, I may paint the frame myself. I have an automotive HVLP spray setup and a reasonable amount of DIY experience. But ideally Ill just leave it matte black.
So anyway, this is the start of a new build on an unknown frame. Cool.
