In this episode Alex is thinking about getting a high end aluminum bike with high end parts as opposed to a carbon frame with mid range parts. Alex is afraid to buy a nice carbon frame because he's still finishing growing. Alex reasons that he could just buy a nice carbon frame after he's done growing and then just transplant the parts. However Alex does love carbon fiber. What will happen? Will he end up with carbon or aluminum? Who knows! Find out in the next episode of "Alex's Bike Delima!"
