The FSA Gossamer Compact Crankset is a pretty standard budget oriented, aluminum compact crankset designed to work with the FSA MegaExo bottom bracket. The crank arms are not hollow or carbon, but cold forged aluminum. This makes them relatively strong and stiff, but a little heavier with more flex than higher end offerings. The 50/34 chainring group is 7075 aluminum and has been custom machined to ensure clean and accurate shifting. The FSA Gossmer is designed to work with Shimano 9 and 10 speed drivetrains. If you're going from a triple to a compact double, check with the mechanic at your local bike shop because you may need a double specific front derailleur.
The MegaExo bottom bracket has gotten mixed reviews from riders. Some complain that it lacks durability and tends to wear out after 1000 miles, others have complained about the cranks arms coming loose, causing the bb to make clicking sounds. It's probably a good idea to have this compact crankset professionally installed and inspected on a regular basis.

The FSA Gossamer compact crankset is a good choice if you want to experiment with a compact double and don't want to spend too much money. If you look around you can probably find one of these on Ebay for around $100. Worse come to worse, you'll probably get one or two seasons out of it before you need to replace it with something lighter and better quality. The crankset has a Q-Factor of 147mm and is offered in 170, 172.5, or 175mm crank-arm lengths.
