Question: What are the negatives of a carbon fibre bike frame? Scratches? Weight limits?Hi Joan, This is a nice topical question, if you look at the Pro peloton at the moment most riders are on a carbon fibre frame, there are still one or two on alloy, but, I bet they have carbon fibre forks and probably carbon fibre rear chain stays and seat stays.OK so you want to know the problems with Carbon Fibre, right first if you fall off and damage the frame, you will probably have to throw it away as it is more than likely impossibly to fix.
If the carbon is damaged that’s it, if one of the wheel ends or the gear hanger is bent they might be able to be straightened, but otherwise forget it.Scratches don’t seem to be a problem, but I have not put it to the test on my frame, I don’t think there are any weight limits, not as with some alloy frames they have a 70 or 80 Kg.
All this said I wouldn’t ride anything else, Carbon is King!
