Madone SLR G8 Integrt Headset 5mm Black 2-Piece

The Trek Madone SLR G8 headset spacer is a genuine replacement part that fits Trek Madone SL and SLR Gen 8 framesets as well as Checkmate models equipped with the RCS integrated headset system. Supplied in black, this 2-piece spacer kit lets riders fine-tune stack height at the front end without altering the bike's aero profile.

Each spacer measures 5mm thick with a 28.6mm diameter, matching the steerer tube dimensions used on these framesets. Keeping spacers genuine to Trek helps maintain proper fit and finish around the RCS cockpit, making small adjustments straightforward during a fit session or after a stem swap.
