FRAME MINIMUM
INSERTION:
75mm FROM TOP OF
COLLAR
FIG. 3: Determine the saddle height.
• Both the frame and seatpost have minimum insertion requirements. In addition, the frame has a
maximum insertion requirement to prevent damage to the tire cutout area.
• MINIMUM INSERTION: The seatpost must be inserted into the frame deep enough so the
minimum insertion/maximum extension (min/max) mark on the seatpost is not visible. The frame
requires a minimum of 75mm of insertion.
• MAXIMUM INSERTION: The seat tube can accommodate up to 215mm of seatpost insertion.
• If the post is at the minimum or maximum insertion and the saddle is not at the desired position, the
seatpost must be replaced with a longer or shorter seatpost.
• Fig. 2: Once the saddle height is determined torque the seat collar bolt to 55 in-lbf (6.2 Nm).
SEATPOST
MINIMUM
INSERTION
MAXIMUM
INSERTION
The Aethos seatpost is available in two lengths (300mm and 360mm). If the
360mm post is too long, we recommend using the 300mm seatpost.
Do not apply grease to the contact surfaces between the seatpost and the
seat tube. Grease reduces the friction, which is critical to proper seatpost grip.
Specialized recommends the application of carbon assembly compound (fiber
paste), which can increase friction between carbon surfaces. Please visit your
Specialized Authorized Retailer for additional information.
WARNING! Failure to follow the seatpost and frame insertion requirements
(fig. 3) may result in damage to the frame and/or seatpost, which could
cause you to lose control and fall.
WARNING! For general instructions regarding the installation of the seatpost,
refer to the appropriate section in the Owner's Manual. Riding with an
improperly tightened seatpost can allow the saddle and seatpost to slide down,
which can damage the frame and cause you to lose control and fall.
WARNING! Inspect the seatpost and seat tube to ensure that there are no burrs
or sharp edges. Remove any burrs or sharp edges using fine grit sandpaper.
