1. The most important thing about buying a new bike is to make sure it fits. The only way you'll know if the bike is right for you is to size up the bike and make sure that the bike's geometry matches your body's geometry. Ask questions and do some research.

2. If possible, try to find a shop that will let you demo the bike on real dirt. Five minutes in a parking lot won't cut it. You wouldn't buy a car without a real world test drive, and a bike should be no different.
3. Don't belive the hype. Just because your favorite rider or best friend rides a certain bike, that doesn't mean that's the best one for you. Have an open mind and be realistic about your needs and ability.

    Used that green shimano grease on my BB & the excess has stained my frame!

    How do I get it off? It's like a really thin film.

    Has it permanently stained the carbon?

    Hard to believe the stain is permanent. Have you tried to just wipe the grease off with a clean rag?

    I'm not sure which chemicals are safe on carbon. Perhaps a bit of rubbing alcohol? Dampen a rag w/it maybe?

    Maybe just try a bit of soap and water first. See what happens.

    Give me your address and I'll send you some tissues.

    I don't have any personal experience with stains on carbon but try some car wax and a microfiber cloth. I have a feeling that would work (if it doesn't remove the car wax with rubbing alcohol so it doesn't coat over it making it harder to remove). Another thing to try could be WD40... and if all else fails try Mr. Clean eraser cleaning pads (basically a 2200+ grit wet sponge).
    Killing it with close inspection.

    Carbon is black. A green grease stain would be nearly invisible.

    You can remove grease with a degreaser.

    The trouble with common sense is it is no longer common

    I have a feeling that some degreasers will dull the polished finish of carbon. I would try the least aggresive methods first. Use polymer safe degreaser if you go that route.

    Sure, some, but far from all. Dawn dish soap is a degreaser. And you are cleaning the finish coating the carbon, not the carbon itself.

    Dawn dish soap. Scientifically shown to be the most gentle soap. It's what they use to clean oiled seabirds. Really.

    seriously, carbon is pretty tough. Even the resin is not easily broken down. Remember this is a space age material. In fact, its so tough to break down that there is no real way to recycle it. Most of it just gets landfilled. So most solvents won't really hurt the carbon at all. Now the paint is another story.
