I ride my carbon frame all year round. The guys in the club often comment on it in the dead of winter. The one thing I will say is that if dirt and water gets into frames /bearings / nuts&bolts etc.. because its carbon, any knock/squeak/ping etc.. tends to get multiplied and sound worse than it is. So ride away and clean afterwards is my advice.

I left mine in the sun after cleaning and polishing it. Went off to have a bath, and when i came back, all that was left was sticky pool of black stuff and a pile of bike parts.

You were lucky it didn't burst into flames.

he reckoned it was because the mud had got into the gaps between the strands of the carbon

I suspect the mud got in the gap between his ears.

Best leave it at home: someone might nick and make pencils out of it.

Indeed. With all of the carbon parts used on cars (not many of the F1 cars disintegrated last weekend in Melbourne, for instance), you'd think that this myth would have started to dissolve.

Carbon fibre boats like this $2m beauty or, at the other end of the scale, this would be in trouble too.

Unfortunately the rain DOES effect some carbon bikes - Honestly!

The carbon doesn't normally get damaged directly, it gets damaged by the metal parts that are bonded / fastened to it.

Cheaper carbon frames often have aluminium lugs and even the more expensive frames often use aluminium seatposts, bottom brackets and dropouts.

What happens to the water that gets into the BB area? I have had quite surprising amounts of water pouring out when I have upended the bike. Maybe the drain hole is blocked.

The front derailleur cable goes right through the middle of this area but I guess it's stainless so damp shouldn't affect it.

Are you talking about cathodic corrosion?

Q: On your web site you have indicated that aluminum and carbon fibre react so as to cause cathodic corrosion. Is this also the case with steel or cromoly steel and carbon fibre?
A: Yes, it is a problem with steels as well as with aluminum alloys. The easy solution is to prevent contact. One way to do this is to include a single light ply of fiberglass in the layup as an electrical insulator between the metal and carbon. Trek did this with their bonded aluminum lug carbon tube bikes. Specialized did too, and Kestrel uses small patches of fiberglass in the fork and frame where metal parts attach. Aerospace structures do the same. See NASA's document TM-584C, CORROSION CONTROL AND TREATMENT MANUAL.

That's because you live in a hard water area, you need to fit a filter.

Um....the carbon frame doesn't look so bad!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
