Review by Rosey
I used these chainrings to replace older Dura-Ace set. I wanted to lower the front gear ratio and these worked perfect. Shifts better because they are ramped and pinned plus I also liked the fact that they had a steel pin on the outer ring. Outer pins help keep your chain from falling into the cranks. Good quality and worth the price.

I switch the original chainrings on my BB30 FSA SLK crankset from 5339 to a 5039 they work fine and also look great. The sale price was a perfect deal for me.

Use it for training and racing, Strong and light, Chain rests well as like in a fitted glove. No problem recieving the chain or giving it up as I switch my gears often from my 38 to my new 50. Nice compact gearing without the cost of having to buy a new crank.

Performs well.....went on easily. Have put several hundred miles on the ring and have no reason to believe we will have any trouble with it.
