Carbon fiber $350 hardtail 27.5 MTB frame

[spinningmagnets]

The size listed as 15.5 inches (center of bottom bracket to top of seat-tube?).

Lixada brand. Most certainly Chinese made. Absolutely no details provided on BB width, seat-post diameter, or head tube style (1-1/8th preferred). would like to know what is the widest tire that can be fitted...

You should check on amazon for MTB carbon fiber frames. You will find better than Wallmart for about the same price, much better for little more. Most of those are old new stock, going for a fraction of the listed price.

I don't know what "better" would look like, and I have been keeping my eye out for Chinese CF frames for a while. Some will be crap, but some might be good performance per cost...What (in your opinion) are the best three 27.5 CF frames for under $400?

27.5 a must ? 15.5 size too ? The frame you link is too lightweight for a good MTB, it is closer to a street racing frame IMO.
New old stock, are mostly 26 or 29
Size 15 to 16 is small, size 17 to 18 med, 19 to 20 large

Good CF frames are made in Taiwan, or western world. Very few good CF jobs out of China, so better check feedback and reviews with those. One example of good spec Chinese frame:

Hi
If I have the onor of giving some advice at the veterans here if you want a huge tyre why you do not consider a transition transam 29" it is made from real steel it will last for ever you could find it used at very low prices and you could use it also with 26" 2.7 tyres like maxxis minion dhf dual ply.

 

[spinningmagnets]

Thank you, spiros. I will look into those.

there is also another company that i love for hardtails the ONONE BIKES
check them they are a good company and you find frequently great discounts they use all materials carbon steel alluminium and TITANIUM!!!!!!!

I’m hesitant to get off brand carbon fiber. From everything I have read, there is an art to the design and lay up – and there is no good way to measure that quality. Seems like steel or aluminum is a lot more basic and harder to mess up.

A casually made carbon fiber frame is going to be no better than a good frame of a more traditional quality. Similarly with titanium – they tend to crack too easily if not welded well. Don’t need that!

I did get an off brand carbon fork (nashbar, but it has no redeeming qualities that I can think of. Stiff as a brick.

But hey, if you find something different, let me know!
