FSA Gossamer Pro Crankset

This crankset is specifically optimized for gravel and adventure riding. The sub-compact 46/30T gearing is designed to help you maintain a comfortable cadence on steep climbs and loose terrain where standard road gearing might feel too heavy.

The Gossamer Pro uses the 386EVO spindle standard. Because of its modular design, it is highly adaptable, but you will need to ensure your frame is compatible with 386EVO or that you have the correct adapter for your specific bottom bracket shell.

Yes, the modular design allows for flexibility. However, keep in mind that it utilizes a specific 120/90mm bolt circle diameter, so you will need to source replacement rings that match this specific pattern.

Crank arm length is a personal preference often tied to rider height and leg length. A 170mm arm is a standard length that works well for a wide range of riders, offering a balanced feel between leverage and pedal clearance.

While it is designed for gravel, it functions perfectly with most standard road drivetrains. Just ensure your front derailleur has the range to handle the 46/30T sub-compact chainring configuration.
