Align the saddle with the frame by using the saddle
nose and the bottom bracket or top tube as a refer-
ence point.
Clamp the seat post tight again by closing the
quick-release
(d)
, as described in chapter “How to
use the quick-releases” or by turning the seat post
binder bolts clockwise in half turns
(e)
. You should
not need much strength in your hands to clamp the
seat post sufficiently tight. Otherwise the seat post
does not match the frame.
Verify in between that the seat post is sufficiently tight
by taking hold of the saddle at both ends and then
trying to rotate the seat post inside the seat tube
(f)
.
If it does rotate, gently retighten the binder bolt of
the seat post clamp by half a turn and do the check
again.
Does the leg stretch test now produce the correct
result
(g)
? Check by moving your foot and pedal to
the lowest point. When the ball of your foot is exactly
above the pedal center in the ideal pedaling position,
your knee should be slightly bent. If yes, the saddle
height is adjusted to the correct height.
Check whether you can touch the ground safely
while sitting on the saddle by stretching your feet to
the floor. If not, you should lower the saddle until you
can, at least to begin with.
G
Never apply grease or oil into a seat
tube of a frame made of carbon unless
an alloy sleeve is inside the frame. If you
mount a carbon seat post, do not put any grease
on it, even if the frame is made of metal. Once
greased, carbon components may never again
ensure reliable clamping! Use special carbon as-
sembly paste instead.
G
Make sure not to overtighten the binder
bolt of the seat post clamp. Otherwise
you may damage the seat post or the
frame. Risk of an accident!
G
Never ride your bike with the seat post
drawn out beyond the limit, maximum,
or stop mark
(h)
! The seat post might
break or cause severe damage to the frame. In
the case of frames with seat tubes that extend
beyond the top of the frame’s top tube the seat
post should be inserted into the seat tube at least
below the bottom of the top tube and below the
top of the rear stays! If seat post and frame re-
quire different minimum insertion depths, you
should opt for the deeper insertion depth.
A
If the seat post does not move easily in-
side the seat tube or if it cannot be tight-
ened sufficiently, ask your CENTURION
dealer for advice. Do not use brute force!
