Shimano 105 CS-R7100 Cassette 11-34 vs SRAM GX Eagle Rear Derailleur
Not compatible
SRAM 12-speed derailleurs pair only with XD/XDR-driver cassettes, not HG (Hyperglide).
Why this verdict
- • SRAM GX Eagle Rear Derailleur is a SRAM 12-speed (AXS/Eagle) rear derailleur.
- • Shimano 105 CS-R7100 Cassette 11-34 uses a HG (Hyperglide) driver body.
- • SRAM has never produced a 12-speed cassette on an HG or Microspline driver — every SRAM 12-speed cassette is XD or XDR only.
