Carbon seatstays

[daggavis]

Can anyone tell me if carbon rear stays really makes a difference and how durable they are...curious about silverback monterey..

They look good, and should take some of the road vibration away, but they also add quite a bit of weight to the frame.

 

In my opinion you are better off going for something like the hourglass seat stays on the Cannondales, that also eliminate vibration, but dont add the weight.

I agree, carbon seatstays are a waste of time. You are better of going for the new CAAD9 frame from cannondale. Very comfy bike according to reviews, light and no issues with glue joints pulling apart.

The Montery is a damn side cheaper than the CAAD9 and it must be remembered that the Montery has a full carbon triangle (not just the seat stay)

I've often wondered about the benefits of carbon stays too. Would a full carbon triangle have a better benefit than the plain seat stay one?

I really like the all alu CAAD9 5, but the price tag of R14k is steep..

Full carbon rear ends just add weight to a bike. They still need a large plug to be inserted in to the frame to bond the carbon to aluminium. Plus the small section of carbon means they have to use quite a bit of it to make the rear stif enough to compete with a well design aluminium frame.

I'd say either go full Carbon , or full aluminium.

They're purely aesthetic and thus makes a difference in looks. If you have two of the same bikes, one with alu and one with carbon stays, you won't notice the difference. Further, no fancy shape in the stays (such as hourglass shapes) provide any form of suspension. Seatstays are for all intents and purposes perfectly stiff in the lateral plane.

 

As for durability, they're not very durable. Carbon doesn't like impacts from sharp objects. The resin cracks and then you have a mushy wound that ruins the frame.

 

I recently toppled my alu bike on a stair and the stay was dented. The bike is still perfectly rideable. Had this been a carbon stay the frame would have been ruined.

I have a Specialized Allez Pro frame with Carbon stays and Zerts gel inserts that damp vibrations from the road. This does seem to have an effect on the ride comfort as it rides smoother on rough roads.

 

This was developed for the Paris - Roubaix Pave roads so I am sure there is merit in the logic.

Specialized = excellent BS marketing.

 

any change in section in the tube will act as a vibration damper, or rather change the frequency and amplitude of the vibration.

 

CAAD9 vibration damping is a result of the design of the frame and the sections used. The Hourglass stays just make it easier for them to tell you that they did somethimng to damp the vibes, same with "Zits" or whatever they are.

Buy this baby, light, stiff and beautiful. Just add Campy and you are ready to roll. Its been on Bikebay for ages now, surprised no one has picked it up.

So you actually rode and compared with the Specialized to come to your conclusion or is this based on an emotional bias to your brand of choice?
