Question about cannondale six13

Question

hi guys, i would like to know whether is it worth to get a cannondale six13 and i would like to know whether the area of the carbon and aluminum will flex overtime?

Answer 1

Cannondale makes fine products (or at least it did until it was recently bought out by Pacific, the largest seller of cheap bikes in the world).  However, I've long been skeptical of bicycle frames made of dissimilar materials.  

I know that aluminum frames with carbon seat stays are very popular, because they are cheap to manufacture, but joining dissimilar materials introduces joints that are more likely to fail.

Long ago I purchased the first carbon frame that Look ever made and it consisted of carbon tubes bonded to aluminum lugs.  It was awful.  Trek and Specialized both sold a lot of bikes made the same way, with mixed results.

Seven has had some success with this approach, but only in very high-priced custom frames like the Odonata mixing titanium and carbon, not aluminum and carbon.

Final answer: I'd stay away from it.  If you go carbon, go carbon all the way.  I've owned many carbon bikes and the modern monocoque ones are terrific.
