MANDIBULA SEATPOST
INSTRUCTION BOOK
NOTICE
Please do not cut or grind the seatpost at any time.
Make sure to remove all sharp edges and burrs over the whole insert
depth inside the seat tube or the reducing sleeve (optional). If you
have to rework the seat tube use a reamer.
The inner diameter of the seat tube should be around 0.05 – 0.1 mm
bigger than the seatpost diameter.
The seatpost should slide easily into the seat tube. When sliding in it
should not rattle around the seat tube. There should be a little bit of
resistance when sliding in the seatpost.
Please check the manual of the mating component (frame,
seatclamp) for the recommended torque. Always use the lower torque
recommendation!
PRE-WORK ON THE FRAME
Before assembling the seatpost into your frame degrease the seat tube.
(for example, with brake degreaser).
INFO
Apply carbon paste on the cylindric (Ø 27.2 mm) part of the seatpost
and into the seat tube of the frame.
INSERTING THE SEATPOST WITH SADDLE
Loosen the seat clamp (10) screw fully. Slide the assembled group
(seatpost and saddle) into the seat tube (11) at your roughly desired
height. The saddle should be lined up with the top tube (12).
Now tighten the seat-clamp at max. 5 N•m (45 Ibf •in).
Apply carbon paste and slide
in the seatpost with just some
resistance.
Tighten the seat clamp screw up
to max. 5 N•m (45 Ibf•in).

WARNING
The minimum insert depth is 100 mm for the THM Mandibula seatpost.
ADJUSTING THE SADDLE ANGLE
Loosen the saddle clamping screw (8) fully before adjusting the
saddle angle.
THM recommends to use a bubble level (13) to check
if the saddle is horizontal. If you prefer another angle adjust it to
your preferences. Tighten the T20 Torx screw with max. 8 N•m (71
lbf•in).
(Figure 10) side view
After tightening the saddle clamp, you have to settle the half shells.
You can do it by pushing down (around 7 kg) on the saddle front until
it makes a click sound. Afterwards you have to retighten the saddle
clamp screw with max. 8 N•m (71 lbf•in).
