Start with your frame
The frame sets the constraints. We use its interfaces to narrow every choice that follows.
Built for modern street and gravel bikes
Choose a frameset, add components, and catch mismatched standards before they become expensive mistakes.

In stock, priced, linked, and imaged
Looking for a part you already own?
In-stock parts appear by default. Turn off the availability filter to include reviewed out-of-stock parts and components without current offers.
A BETTER WAY TO PLAN
The frame sets the constraints. We use its interfaces to narrow every choice that follows.
Every warning names the parts, interface, and rule involved. “Unknown” stays visible when data is missing.
Create a read-only snapshot and send the exact build to a friend, mechanic, or riding group.
HONEST BY DESIGN
BikePartPicker is built for modern street and gravel bikes, including road, all-road, commuter, fixed-gear, and single-speed builds. Catalog and compatibility coverage are still growing. Missing data never gets a green check.
