ISP Cutting Instructions
A proper saddle height brings out the best performance and comfort in your bicycle.
To meet the correct saddle height, the integrated seat post might require cutting off
at a specific length. Since the cutting of the ISP is a precision task requiring training
and experience, only Giant dealers should complete the authorized process.
STEP1.
Install the saddle onto the seatpost using the included saddle clamp mechanism.
Put the saddle in a horizontal position and then determine the length to be cut.
NOTE
! The additional range (20mm) of saddle height adjustment (utilizing the
included spacers) provides fine-turning adjustment after the ISP is cut.
NOTE!
The final cut length must not exceed the Maximum Cutting Length limits (see
chart below). Cutting the ISP below this limit may result in the inability to attach the
seat clamp or structural failure of the ISP.
STEP2.
Loosen the saddle clamp bolt and remove the saddle
STEP3.
First, lay your frame flat on a clean surface protecting the finish with a clean soft
cloth at points of contact. Insert the seatpost in the Park Tool SG-7.2 Saw Guide to
the precise location of the desired cut.
Be sure to double-check your measurement.
