Geared Drivetrain¶

1×12 Setups¶

• SRAM GX 12-speed + NX 12-speed cassette: requires 135 mm freehub, 10 mm–11 speed chain.
• Shimano XT M8100 12-speed: works with HG freehub, 2.4 mm chain link.
• Chainline: Aim for ~52 mm chainline with 42 mm Q-factor cranks (e.g., SRAM GX fat cranks).
• Front Derailleurs (if doing 2×): Limited clearance due to chainstay curve; consider E2-style clamp or mid-mount adapter.

2×10 or 2×11 (rare)¶

• Less common—often requires extreme chainstay clearance checks.
• We recommend sticking to 1× setups for maximum tire clearance.
