About Full Speed Ahead (FSA)
Full Speed Ahead, known as FSA, is a bicycle component maker best known for cranksets, headsets and bottom brackets fitted as original equipment on a large share of new road and mountain bikes.
FSA supplies cranks across the common spindle interfaces, including 24 mm external-bearing cranks and its own 386EVO 30 mm spindle platform, which is why FSA is closely associated with the BB386EVO shell standard. Its BB386EVO cranks use a long 30 mm spindle designed to run in a wide range of shells with the matching bottom bracket.
What it makes for your frame
FSA headsets follow the SHIS sizing convention, and the company produces integrated and semi-integrated headsets for the tapered steerers used on modern frames. For fitment, the two questions that matter are the crank spindle diameter and the shell standard, because an FSA 386EVO crank needs a 386EVO-compatible bottom bracket for your shell.
FSA also owns the Vision brand used on its aero and time-trial components. Across the range the fitment logic is the same as any other maker: match the crank spindle to the shell with the correct bottom bracket.
Choosing the right part
With Full Speed Ahead (FSA), as with any maker, the frame decides the fitment. Identify your bottom bracket shell and crank spindle, or your headset and seatpost standards, then choose the Full Speed Ahead (FSA) part built for that standard.
The fitment tool returns the exact bottom bracket for your shell and crank, including whether it drops in, needs a specific bearing or needs an adapter, so a brand choice never becomes a fitment gamble.
Before buying, measure the shell width face to face and confirm the crank spindle diameter, because a Full Speed Ahead (FSA) bottom bracket is chosen by both the shell standard and its road or mountain width. A part that suits one width will not seat correctly in the other, even when the standard name is the same.
