Genuine Trek original-equipment replacement front brake caliper for compatible Madone SLR bicycles. This integrated direct-mount rim brake is configured with brake pads intended for aluminum or alloy rim brake tracks.
This listing is for the front brake caliper. It is not interchangeable with the rear brake and does not include the external aerodynamic brake cover unless that cover is shown in the photos.
The installed brake pads are intended for alloy rim brake tracks. Do not use them on carbon braking surfaces unless their compatibility is specifically approved by the rim and brake-pad manufacturers.
This is a model-specific Trek service part and is not a universal direct-mount brake. Please verify part number W559499, your Madone model year, brake configuration, and rim braking surface before ordering. Installation and final brake adjustment should be completed by a qualified bicycle mechanic.
This item comes exactly as pictured. Please review all photos for the included brake pads, mounting hardware, covers, packaging, and condition.
