No one studies the design and manufacturing of each system, and each tooth, as carefully as FSA does. This dedication has helped Full Speed Ahead to become a world leader for high-end chainrings. FSA uses the best materials available to meet or exceed the needs of any drivetrain, and to guarantee the durability, performance, and appearance will out perform, and outlast the competition. These rings are an ideal upgrade for those looking to improve shifting performance or save some weight over their current set up.
Made of 7075-T6 aluminum these rings are both light weight and strong
Ramped and pinned for smooth and precise shifts
Five bolt pattern is compatible with Shimano and SRAM cranks
Used this FSA 42t to replace the stock 39T on a Shimano Ultegra 6700 (130mm BCD)that came on my Colnago CLX-2. Works great and now I have the same chainring gears as my 35yr old Colnago Super (42-52). I love it!
PROS: Lightweight, Easy To Install, Precise Shifting
