Haha. I think all dual crown forks looks crap but that is just personal opinion.
Gordan, I am also building up an FM10 and, to me at least, that fork has no place on an FM10 or any other bike I own.  That is trying to be a full on downhill fork, it may even have succeeded, I don't know. That fork is heavy, has too much travel for an FM10 and is more than likely over engineered for the type of riding someone owning an FM10 is likely to be doing.
The term horses for courses refers to using the right equipment for the right job. You wouldn't put a draft horse into a sprint race and nor would you try to haul a beer lorry with a young sprint horse.
I have picked up a second hand Rhythm 150mm 27.5 fork to use on my build.  I am confident it will fit the +tyres but I do think my axle to crown height will be lower than optimal. IE, I will have steepened both seat and head angle and dropped the BB height marginally.  If it doesn't work then I will possibly get a crown race spacer thanks to Guitsboys suggestion, until I can find a 29er in my price range.  You could look at picking up a second hand fork or something along the lines of a new RS Yaris that are getting good reviews as a budget fork. Hope all that makes sense, feel free to ask if not. As I said, if Himalo made a 150mm travel 29er or a 160mm travel 27.5 that had thicker than 32mm uppers, was boost spaced and had a 15mm thru axle then I would have tried one, but they don't and the fork linked above isn't a substitute for one.

Excellent, well explained advice. Thank you.

horses for course and a dual crown at well over 3kg, 170mm travel, straight 1 1/8 steerer and 20mm thru axle, that horse doesn't have a course in this house.

Can you explain what you mean by this? I don't understand.

Don't you think Chinese components improve?
There are some brands that start to become something.
And such build could be seen as a starting point, that can then be upgraded if necessary later.

Yeah this was my thoughts exactly. I'm just going to replace stuff as it breaks and see how it goes.

Hello, everyone. I'm looking to build a TanTan FM10 Frame. (Unless anyone has any suggestions for a better frame for 2020?). Here's my current build list so far.
I know the fork is pretty questionable but its only temporary at the moment and I saw it got some rave reviews for how cheap it was. I also will be buying brake rotors, bar, stem, seat, grips, tires, etc on amazon. Does anyone have any suggestions for the rear shock? What's the best for the geometry with 160mm travel fork? 200x57? Would this DNM 200mm 52mm travel shock work?
Was also going to just get some cheap 29er aluminum wheels on amazon unless anyone has any suggestions on good carbon wheels.

Other than that does this build look alright? Anything I'm missing? Thank you guys in advance, awesome to find a community like this.

EDIT: New buildlist after some advice, SX groupset to GX, 4 piston breaks, thru axle fork. Probably wont end up getting that fork but its a placeholder for now.
Still need some advice on 29er wheels for this.
