Shimano 105 Crankset

No, this specific model is engineered exclusively for 12-speed drivetrains. Using it with an 11-speed system will likely result in poor shifting performance and potential chain drop.

This crankset has a Q-factor of 148 mm. This measurement represents the distance between the crank arms, which affects your stance width on the bike; 148 mm is a standard road width that balances efficient power transfer with natural leg alignment for most riders.

Yes, it uses the Hollowtech II interface. You will need a compatible Hollowtech II bottom bracket shell to install it, which is a widely available standard for modern road bikes.

The Hollowtech II design uses a hollow aluminum structure to remove excess material from the center of the crank arms. This reduces rotational weight, making the crank feel more responsive during accelerations without sacrificing the stiffness needed for efficient power transfer.

The resin ribs are designed to reinforce the chainrings, preventing them from flexing under high pedaling loads. This added rigidity ensures that your chain moves smoothly and precisely between gears, even when you are shifting under pressure.

Yes, this crankset uses a standard 4-bolt mounting pattern. While the included chainrings are optimized for performance, the 4-bolt design allows for replacement or customization if you need to change gear ratios later.
