Thanks, mtnwing, for actually knowing what you're talking about and saving me the trouble of writing the exact same things. No one else, not even BMXTRIX (and I respect his opinion, but it's not very up to date on composite technology, and why would it be?) had anything current or remotely accurate to say on the matter.

The #1 reason (I believe) carbon is not popular in BMX is price. BMXers don't have deep pockets, roadies *do*. The other major factor involved is a general lack of interest in R&D from companies with the means to develop and produce strong, lightweight, reliable and perfectly safe carbon components. Big companies know BMX isn't a moneymaker and don't throw a lot of money *into* it. And the top-shelf BMX equipment is primarily produced by small, grassroots comanies with little to no actual R&D capability beyond a few pro riders who say, "This broke, let's make it beefier," or "This is too beefy, let's make it lighter." That is NOT engineering.
