SRAM has streamlined its Eagle drivetrain lineup by consolidating nine existing groups into a more straightforward system: the Eagle S-Series. This new lineup comprises three tiers—S100, S200, and S500—designed to simplify component selection and enhance compatibility across various cycling disciplines.
Eagle S-Series Overview
The S-Series introduces a cohesive ecosystem that caters to a wide range of riders, from enthusiasts to professionals. By merging previous models, SRAM aims to provide a more intuitive and efficient experience for cyclists.
Tier Breakdown
-
S100: This entry-level group offers reliable mechanical shifting, making it ideal for riders seeking durability and value. The S100 features a 455% gear range, accommodating diverse riding styles. Cranksets are available in lengths from 155mm to 175mm, utilizing SRAM’s PowerSpline bottom bracket technology. The PG-1210 cassette, compatible with Shimano HG freehub bodies, is available for €95, and the S100 chain is priced at €35. (velomag.eu)
-
S200: Targeting mid-level riders, the S200 combines performance and affordability. It offers a 520% gear range, thanks to a larger 52-10t cassette. The shifter is Matchmaker-compatible, instead of using a band clamp, and costs €45. The S200 derailleur is described as a workhorse and uses SRAM’s Type 3 clutch: it costs €145. The S200 crank (without chainring) is €90, the recommended XG-1275 cassette is €240, and the S200 chain is €45. (bikeradar.com)
-
S500 AXS: As the flagship electronic group, the S500 AXS brings wireless shifting to riders without UDH compatibility. The electronic derailleur costs €425 and uses the Overload Clutch found on SRAM’s more expensive AXS derailleurs, which disengages the motor-gearbox in the derailleur during an impact before returning to its original position. No specific S500 shifter is listed on SRAM’s website, but it will be compatible with both its AXS road and MTB shifters. The S500 chain costs €110, is available in Gold or Rainbow and is ebike-compatible. The SRAM-recommended XG-1299 cassette is available in Gold or Rainbow for €595. (bikeradar.com)
Key Features
-
UDH Half Mount: Exclusive to the S100 model, the UDH Half Mount provides additional protection against incidental knocks and slams by supporting the standard hanger. It offers more protection than a standard hanger but is not as robust as the full-mount system found in SRAM’s Transmission range. (support.sram.com)
-
Compatibility: The S-Series components are designed to be interchangeable within the ecosystem, allowing riders to mix and match parts across the S100, S200, and S500 tiers. However, components from the S-Series are not compatible with SRAM’s Transmission range due to different cable pull ratios and design specifications. (support.sram.com)
Conclusion
SRAM’s Eagle S-Series represents a significant evolution in drivetrain technology, offering a simplified and cohesive system that caters to a broad spectrum of riders. By consolidating previous models into three distinct tiers, SRAM aims to enhance the cycling experience through improved compatibility, performance, and value.
