5.2. SEATPOST MINIMUM / MAXIMUM INSERTION
Both the frame and seatpost have
minimum insertion requirements. In
addition, the frame has a maximum
insertion requirement to prevent damage
to the frame and seatpost.
Minimum insertion:
The seatpost must be inserted into the
frame deep enough so the minimum
insertion/maximum extension (min/
max) mark (B) on the seatpost is not
visible. The frame requires a minimum
of 80 mm of insertion.
Maximum insertion:
The seat tube is reamed to a specified
maximum insertion depth (A) for each
frame size. This ream depth limits the
insertion depth of the seatpost.

XS S M L XL
Minimum insertion (mm) 80
Maximum insertion (mm) 220 220 244 285 330
Once the saddle height is determined, using a torque wrench and 4 mm
hex bit, torque the supplied seatpost clamp bolt to 6.2 Nm / 55 in-lbf.
If the desired seat height cannot be achieved within the minimum
and maximum insertion requirements, the seatpost should be
replaced with a shorter or longer one.

WARNING! Failure to follow the seatpost insertion requirements
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.
5.3. BOTTOM BRACKET
All models have a threaded 73 mm width bottom bracket shell and are
compatible with any BSA threaded outboard bearing bottom bracket.
Please refer to the crank manufacturer documentation for bottom bracket
compatibility. Before installing the bottom bracket and crank, make sure
all housings and wires are routed through the frame.
CAUTION:
Do not face the bottom bracket shell! This can prevent
proper installation of the crank. Your Specialized frame does not
require any bottom bracket shell pre-installation preparation, as
all surfaces have been precisely machined to specific tolerances at
the factory for proper interface with a compatible crankset. Please
refer to the manufacturer's instructions for crank and bottom
bracket installation.
CAUTION: Always use a bottom bracket equipped with a sleeve
between the two cups. Running a bottom bracket without the
sleeve can result in housings and/or wires contacting the crank
spindle, which can result in wear.
