Bicycle Mechanics - Carbon fibre chainguards?

Anyone know anyone who supplies lightweight carbon fibre chainguards?

By saying chain guard protector are you saying chain stay protector that prevents the chain from scatching or gouging the stay, or chain guard protector to prevent your pants from getting into the chainrings while cycling?

see the following for chain stay protectors: http://www.cambriabicycleoutfitters.com/chain&guide/chains.htm

As far as chain guard protectors that could be difficult to find since they are generally found only on children bikes. Try a pant leg band works just as good.

Or do you mean for downhilling and cyclocross? If so, I would imagine CF would be the worst kind of material for that purpose. It might simply shatter. Or maybe I'm talking nonsense....

Bash rings perhaps?

FSA makes them, 130mm Bolt circle, sized to work with either a 42 or 44t chainring.

Hi.

Thanks for your repsonses. I definitely mean chainguard. (I didn't say chainguard protector). A cover for the chain which I would expect would come in two halves - upper and lower.
This is to fit a Rohloff equipped touring bike and is intended to protect the chain - and in my case, to help to hide the Rohloff and also to make the bike look a bit more ordinary and to discourage some thieves.
I'm sure that some poeple will want to discuss the usefulness of this idea, but regardless of that, I'd still be grateful for any info as to anyone who makes such a thing.

Thanks

wait a second.

you want to make a bike look less desirable to thieves by bolting on a bunch of carbon fiber?

something doesn't compute.

It's nice to receive everyone's concern. However, I don't understand why people tend to think that the only quality of carbon fibre is that it is used in order to look more sexy.
Its other qualities include at least that it it light, it is strong, and it can be painted over.

Sounds like a perfectly good idea to me, and something you can fabricate yourself. There is some advice on carbon stuff at Sheldon Brown website. You make a inner mould from polystyrene, wrap it in clingfilm, and coat it in carbon weave, then paint with resin. Its not as snazzy as pressure/heat treated stuff, but very serviceable and will look rough enough not to require paint. You can also mould in some decent mounts.
Have you considered running the chain in an oil bath within the sealed chaincase?

Have you considered running the chain in an oil bath within the sealed chaincase?

Bicycle chains do not need that much lubrication. It would make quite a mess of the chainring and cog.

What mess? They would be covered in oil, and sealed within a chaincase, away from dirt and water. This was how the Sunbeam bike worked. You can get about 50k miles from one chain.
UK designer Mike Burrows has produced some prototype bikes using enclosed carbon chaincases. It really helps, though, to use a mono-stay design, so you dont have to remove the wheel for puncture repairs.

So there is going to be a sealed cover all the way around the chainring? Sure, it could be done. You would have some effeciency loss due dragging the oil around, ie. windage. That is why race cars use a dry sump oiling system.
