what makes road bike SO MUCH lighter than a mtb?
difference in weight for frame isnt that much comparing a hardtail with a road bike. wheels, 29inches on road bike isnt that light too. the crank is also not so light with the huge chain ring. handle bar is heavier than mtb. what makes a road bike a few kg lighter?
Here is the fundamental difference. A mountain bike is optimized for ruggedness. A road bike is optimized for weight and speed.
There is nothing to say that a mountain bike could not be much lighter. In fact, expensive, XC racing bikes are usually quite lightweight. Racers buy them for the best speed in full knowledge they are not buying a real robust bike. Should you take one of these bikes off some decent drops you would be likely to tear it up.
Designed for tame, paved roads, a road bike doesn't need to be at all robust. They can be optimized for the lightest possible weight and highest speed.
You might want to take a look at the following web site to see how light some people can build a mountain (or road) bike:

Hope this helps.
