Carbon stays on a steel or ti bike(6 posts)

Do carbon stays really serve any useful purpose on a well built steel or titanium frame bike? Would they be used for vibration damping purposes, added stiffness, or increased compliance. Seems like they would make sense on an alumiunum frame but why a titanium or steel frame? What possible purpose would carbon chainstays serve on any bike?

As designers continue to tinker with mixing material in frame building, adding carbon into a metal frame is a natural evolution of the industry. For a steel frame, carbon stays will help reduce the overall weight of the frame, which is often the reason cyclists choose Ti or Alu frames. Carbon fibre is a unique material, in that it can be fabricated to have specific characteristics much more easily that steel, Ti, or alu. Simply by changing the angle in which the fibres cross each other can soften of stiffen the final product.

There is no doubt CF has some dampening effects for ride quality. We need not look any further than CF forks to show how it helps.

Perhaps the one greatest concern with mixing CF stays on any steel, Ti, or alu frame is the longevity of the bond between the two materials. I believe this used to be an issue with the original Look CF frames that used Alu lugs.

Only time will tell if this technology will survive. So far it is looking pretty good.

Cycling plus evaluated this recently. The verdict was they functionaly don't add any thing. They certainly don't make the bike worse really more neutral. So what the heck it looks cool. One interesting thing they noted is that it probably makes the frame set easier and cheaper to fabricate particularly the designs that have the one big tube that attaches to the seat tube. So why do they geat a premium for these farmes?
