rim life

Team Banana Spokesman

1) When metal/carbon braking sufrfaces are 'dead' is there a way to 'repair' them?

2) are carbon surfaces better or worse for braking?

3) I would think that the carbon surfaces last longer. true?

magliaceleste

1. No idea
2. Worse from what I hear, especially in the wet
3. False, I think (although since you'd not ride them in the wet maybe true!).

I would have thought if carbon was more durable then Look wouldn't have put metal plates on their carbon Keo Max pedals recently to stop wear.

Must add these are opinions/research rather than first hand experience.

John.T

1/ No.

2/ Worse in the wet and can be less predictable in the dry.

3/ Given the same riding conditions I would say false.

Agree with John T:
1. When rims are worn you bin them
2. Braking on carbon rims is less efficient and grabby - you cannot mould / machine the surface as flat as an aluminium rim and the thermal properties of the material makes it harder to work with a rubber blocks.
3. Carbon is softer than metal and so will wear quicker.

Carbon rims are nothing like as resistant to impact damage - a pothole can finish-off a rim.

The 'carbon' is your pedal cleats is in fact a filled thermoplastic whereas true 'carbon' is typically a matrix or carbon/ compsite fibres witinh a thermoset resin.
