Adjust Your Fit

Ensuring that your new Roubaix is properly fit to you is an important step in preparing for your first ride.  Your Authorized Specialized Retailer will be able to provide a basic fit, ensuring that you are able to ride your Roubaix comfortably and efficiently. Specialized also offers Retül Fit, a data-driven bicycle fitting tool designed to improve comfort, prevent injury, and increase performance. 

Saddle Height 

To adjust the saddle height, begin by moving the rubber grommet up the seatpost to expose the seatpost wedge bolt.  The seatpost wedge bolt may be adjusted with either a 4mm hex or an 8mm socket.  Loosen the wedge bolt and adjust the saddle height as needed.  Ensure that the seatpost is inserted far enough to block the minimum insertion hole (A in image below) on the down tube.  Torque the seatpost wedge bolt to 6.2Nm (55 in-lbf) and slide the rubber seatpost grommet back into the frame.

Roubaix uses a specific D-shaped aero seatpost. There are two sizes available, 380 mm and 450 mm. The frame requires a minimum seatpost insertion of 120.4 mm. See the table below for the maximum seatpost insertion by size and the seatpost length included with each frame size:

Stack Height

Roubaix models equipped with the Future Shock 3.0 have a maximum of 30 mm in stack height measured from the fork steerer tube. If you use the tall (15 mm) headset spacer, you can add a maximum of three 5 mm spacers under the stem. See C and A in image below.
