Chainrings

- CNC machined 7075-T6 aluminum with modified shift gates and special profiles to allow flawless shifting with 9sp and 10sp drivetrains - Middle and outer chainrings have strategically-placed stainless steel pins to further enhance shifting - 5mm thick middle ring, 4mm thick outer ring - Anodized black with laser-etched graphics

Original equipment on SRAM and Truvativ cranks, these chainrings also work well with other drivetrains. - 104mm BCD - Material: Aluminum

- The oversized chainrings are CNC machined 7075 Aluminium blanks—2mm thicker than the competition. - Unparalleled stiffness is delivered by an increased Bolt Circle Diameter (BCD) and a two-piece insert-molded carbon composite construction. - The XX Crank geometry provides a narrow 156mm Q factor, efficient chainline, and beveled crank arms to maximize clearance. - X-Glide is the pure science in action common denominator that gives XX its unmatched shifting performance. - 80mm BCD

Shimano chainrings offer durability and confidence-inspiring performance, and go a long way towards getting a drivetrain back to optimum working condition.

Shifting performance has helped Full Speed Ahead to become a world leader for high-end chainrings. No one studies the design and manufacturing of each system, and each tooth, as carefully as we do. Our dedication shows in every revolution of the crank, and every perfect shift achieved. To meet or exceed the needs of any drivetrain, Full Speed Ahead has developed sophisticated design, testing and manufacturing protocols. This allows Full Speed Ahead to match your needs as perfectly as our chainrings match a chain. We offer more options, levels, and finishes than our competitors. We use the best materials available, imported from the USA, Europe, or sourced from our qualified vendors in Asia, to guarantee the durability, performance, and appearance will out-perform, and outlast the competition. Full Speed Ahead chainrings have powered multiple World, Tour de France, and Olympic champions, and will exceed your expectations. - Stamped AL7075/T6 - Chainrings are compatible with all 10-speed drivetrains, and compatible with FSA, SRAM, and Shimano 11-speed drivetrains - Drivetrain Speeds: 11, 10

SRAM's road chainrings are stamped from 7075 aluminum for low weight and excellent strength. The teeth are ramped for precision shifting, too.

- Trushift chainrings feature shift ramps and pins - Drivetrain compatibility: 8, 9, 10, 11 - 104mm BCD

- Ring Position/Type: Inner - Drivetrain Speeds: 11 - Chainring BCD: 64 Shimano Asymmetric - Material: Aluminum

A tight and consistent 13-tooth gap between chainrings delivers accurate and dependable shifting and is the core of our X-Range gearing. Our smaller chainrings paired with wide-range, 10t-start cassettes provide more efficiency and more time in the big ring. It's modern gearing for today's riders. - Crisp and accurate front shifts - Durable finish - X-Range gearing technology gives you more range and a smoother gear progression, so you're always in the right gear
