Shimano 105 FC-RS520

No, the FC-RS520 is specifically engineered for 12-speed drivetrains. Using it with an 11-speed system will likely result in poor shifting performance and potential chain issues.

This crankset utilizes the Hollowtech II spindle interface. You will need a compatible Hollowtech II bottom bracket that matches your frame's specific shell standard, such as threaded BSA or press-fit options.

Yes, the crankset features an asymmetric 110 BCD design. While you can replace the chainrings, you must ensure any replacements are compatible with this specific asymmetric bolt pattern.

The Q-factor is 150 mm. This measurement represents the distance between the outside of the crank arms, which affects your stance width on the bike and can influence pedaling comfort and efficiency.

While it is designed for road bikes and disc brake setups, its durable construction makes it capable of handling light gravel use. However, it is optimized for road gearing and chainline, so it may not be ideal for dedicated gravel bikes requiring wider tire clearance or specific gearing ratios.
