Shimano XT FC-M8130-1 Crank Arms

No, these specific crank arms are designed exclusively for frames with 157mm O.L.D. spacing, often referred to as Super Boost. They will not provide the correct chainline for a standard 148mm Boost frame.

These cranks use a standard Shimano Hollowtech II outboard bottom bracket interface. You will need a compatible 24mm spindle bottom bracket that fits your frame's shell standard.

While these cranks are optimized for 12-speed systems, they can technically function with 11-speed setups. However, for the best chain retention and shifting performance, we recommend sticking to a 12-speed drivetrain as intended.

The Q-factor is 181mm. This measurement represents the distance between the crank arms, which affects your stance width while pedaling; a wider Q-factor is necessary here to accommodate the wider 157mm rear hub spacing.

No, the FC-M8130-1 is sold as the crank arm set only. You will need to purchase a compatible direct-mount chainring separately to complete the installation.

The hollow forged design removes excess material from the center of the crank arms without sacrificing structural integrity. This results in a lighter overall weight and increased stiffness, which translates to more efficient power transfer with every pedal stroke.
