- Shadow RD+ Rear Derailleur → Low-profile design with clutch for chain stability, reduced slap, and protection against impacts; supports up to 51T low sprocket for massive range.
- SLX Shifters & Brakes → Rapidfire Plus shifters with 2-way release for intuitive control; 4-piston hydraulic disc brakes (M7120) for powerful, modulated stopping in wet or dry conditions.
- Narrow-Wide Chainring & Chain → Dynamic Chain Engagement+ teeth for superior chain retention; HG+ chain for durability and smooth shifting.
- Lightweight & Durable Construction → Aluminum cranks, alloy derailleurs, and sealed bearings keep weight low (full groupset ~1.2–1.4kg) while handling aggressive riding.
