What Our Gearhead(R) Experts Are Saying: "I run this FSA Pro Track ring on my velodrome setup-it's stiff, precise, and built to last. The CNC machining is on point and I love how it transfers every watt straight into speed." When it comes to pushing the pace on the velodrome or flying through fixed-gear crits, the Full Speed Ahead Pro Track 51t Chainring is the edge we count on. This chainring is precision CNC-machined from AL7075/T6 alloy, giving it race-ready stiffness and strength for serious track applications. Its 144mm BCD and 1/2" x 1/8" chain compatibility make it a perfect fit for high-torque, single-speed builds where efficiency matters most. The tooth profile is optimized for flawless chain engagement, and the laser-etched logos remind us we're riding with elite-level hardware every time we drop the hammer.
