What is it?
Some frames have designs that require no less
than a specied length of the seat post to be
inserted inside the frame. This requirement is
more common on high performance carbon
ber mountain bikes, but can exist for other
designs. The frame and the seat post work
together, support each other. Inadequate overlap
of these parts can lead to failure in high load
situations.
Such a minimum seat post insert limit will be
marked on the frame, via a frame decal and/or
in the owner’s manual supplement as “minimum
seat post insert” in the Geometry/Specications
section.
How Does It Aect My Bike?
You must always have at least the required
minimum length of seat post inserted inside the
frame.
WARNING
IF YOUR FRAME HAS A MINIMUM
SEAT POST INSERT DEPTH, MAKE
SURE THE SPECIFIED LENGTH
SEAT POST IS INSTALLED INSIDE
THE SEAT TUBE AT ALL TIMES.
ASK YOUR GT DEALER ABOUT
THIS SPECIFICATION.
Failure to insert the seat post correctly can
improperly stress the frame and/or the seat
post causing the frame to break while riding.
YOU MUST ALSO BE AWARE THAT
bicycle seat posts are permanently marked
by the manufacturer with a “MINIMUM
INSERT” line on the seat post itself.
You must not rely on this marking as an
indication of the proper MINIMUM SEAT
POST INSERTION DEPTH.
YOU CAN BE SEVERELY INJURED,
PARALYZED OR KILLED IN AN
ACCIDENT IF YOU IGNORE THIS
WARNING.
