Always want to assemble a bicycle.

I want to buy a carbon frame. But different frame has different price.

For the carbon mountainbike(cross country), I want to know the difference between a$1000 frame and a$2000 frame.

Depends on how the manufacturer constructed it, and their overhead, and their desired profit margin.

like Lady's of the Evening, it's a safe bet the 2000 one weighs less than the 1000 one. most likely, more attractive too.

Mostly it will be weight. Santa Cruz has a low-end carbon frame and a high-end carbon frame that they sell on their 5010. The geometry is the same, Santa Cruz states the difference is in the carbon to make the high-end lighter thus making it more expensive.

If you are asking this question the answer won't matter to you.

I want to know this question. Friend around me want to know why some frame more expensive, the only reason I know is weight.

I want to know more about it. If you know that ,please tell me .

Have you seen other bicycle like Santa Cruz 5010, have same geometry but different carbon?

A wonderful metaphor.

Bit confused here with what you are asking for, the 5010 is a nice bike/frame, but it's Aluminum, the 5010C & 5010CC are the carbon models. Also, the 5010C/CC is an AM bike, defiantly not a XC bike as you asked about in your first post.

If you were looking at the 5010C/CC here's a link to a review about them BikeRadar Battle: Santa Cruz 5010 CC vs Yeti SB5c - BikeRadar

do you have find the frame ? i also want to buy a set

Thanks a lot, your answer is so helpful for me .

I didn't find a frame yet.

$1000
