Carbon detail

[MTBc]

So after reading through some of the topics on China carbon frames, I decided to do a bit of investigating, and found 2 relatively well-priced suppliers. Still new to biking though, and wondering if someone could explain specs that were sent back by the suppliers on details of the frames and what it means. All feedback on the topic welcome:

 

the weave 3k/12k/UD - assuming this is the quality of the carbon. I read up that UD is "uni directional" and assuming that this would affect the durability of the frame? cross weave sounds more stable to me... 3k is a little flexible, while 12k is stiff. how would this affect riding in different conditions?

 

BB: BSA/BB30 - different options on the bearing, what's the difference?

 

I'm considering the frame as a replacement for a Silverback Vida build up, and wondering what I need to look out for other than the BB and carbon weave (or rather just stick to an established brand?).

 

Looks like the warranty on it is 2 years, don't most locally frame suppliers offer a lifetime warranty?

the carbon underneath is the same - the finish (how it looks in the sun) is either 3K (big squares) 12K (small squares) or UD - no squares.

 

Choose your BB on the crank you have now.. or you will either need an adapter or another crank or BB...
