Framesandgear Disc Brake Adapter for Specialized Tarmac SL8 and S-Works Tarmac SL8 Black

The Framesandgear Disc Brake Adapter for Specialized Tarmac SL8 and S-Works Tarmac SL8 Black gives your Shimano flat-mount brake system a precise mounting position for a 160 mm rotor. It suits riders who want more braking power or need to match rotor size without changing the caliper or modifying the frame. Therefore, it keeps the braking system clean, correctly aligned, and ready to use.

This adapter fits only the groupset and frame type named in the product title. Therefore, confirm your frame's brake mount standard and caliper model before ordering to avoid any alignment issues.

Why use CNC-machined aluminum

7075 CNC-machined aluminum gives the adapter the stiffness and precision needed to hold the caliper in correct alignment with the larger rotor. Because the mounting interface is machined to exact tolerances, the caliper sits flush and centered without shimming or adjustment. As a result, braking feels consistent, and the rotor runs cleanly through the pads on every ride.

Installation

Remove the caliper from the frame or fork and clean the flat-mount interface. Place the adapter against the flat-mount holes and hand-tighten the adapter bolts to confirm correct alignment. Mount the caliper onto the adapter and tighten the caliper bolts gradually. Squeeze the brake lever and hold it while tightening the caliper bolts fully to centre the caliper on the rotor. Spin the wheel and confirm no rotor rub before riding.
