The S200 Eagle Groupset is the go-to choice for riders who demand high-performance mechanical shifting, race-ready weight, and lasting durability. Built from the very best of mechanical Eagle, this kit is designed to elevate any bike it touches.
What's Included:
S200 Eagle DUB Crankset Aluminum crank arms, a steel X-SYNC 2 chainring, and SRAM's DUB spindle platform combine to deliver secure chain retention and reliable power transfer. Available in lengths from 155 mm to 175 mm for a perfect fit on any rider.
S200 Eagle Rear Derailleur The S200 Derailleur is the workhorse that continues Eagle's wide-range 1x legacy. Its proven Type 3 clutch delivers confident chain retention and quiet descending, while full compatibility across both 500% and 520% Eagle cassettes keeps your options open.
S200 XG-1275 Cassette A massive 520% gear range means you'll have the right gear for every climb and descent. Fully compatible across the Eagle ecosystem, it pairs seamlessly with both legacy and current Eagle components.
