Trek FX / FX Sport brake pad questions
The 13 listed builds specify Shimano UR300 calipers with MT201 levers. Shimano lists B-type B03S and B05S pads for BR-UR300. Use the matching collection for your exact bike and check the caliper fitted to it before ordering.
No. Coverage is limited to the exact 13 builds shown for 2021, 2023, 2024 and 2025. It does not establish compatibility for FX 1, FX 2, FX+, other builds or unlisted years. Search Finder for other bikes and confirm their fitted brake.
The manufacturer pages use one shared Brake specification. The guide retains the existing front and rear pad mapping; the sources do not separately list both calipers. Check both brakes if the bike has been modified.
Trek sometimes lists an archive range such as 2022–2023. Each bike here keeps its existing Finder year within that explicit range. The guide does not add other years from the archive range.
