Adjusting the saddle to the correct
height
The correct saddle height depends on the length of
your legs. When pedaling, the ball of your foot should
be positioned above the center of the pedal axle.
With your feet in this position you should not be able
to stretch your legs completely straight at the lowest
point, otherwise your pedaling will become awkward
(a)
.
Check the height of your saddle with flat-soled shoes.
This is best done with suitable cycling shoes.
Rule of thumb to determine the suitable saddle
height:
Inseam length x 0.885
Sit on the saddle and put your heel on the pedal at its
lowest point. Your leg should be fully stretched and
your hips should remain horizontal.
To adjust the saddle height loosen the quick-release
lever (see chapter “How to use quick-releases and
thru axles“) or the binder bolt of the seat post clamp
at the top of the seat tube
(b)
. The latter requires
suitable tools, e.g. an Allen key, with which you turn
the bolt two to three turns counterclockwise. Now
you can perform the vertical adjustment of the seat
post.
Be sure not to pull out the seat post too far – the
mark on the seat post (end, max., min., stop or the
like) should always remain within the seat tube
(c)
– and always grease the part of an aluminum or tita-
nium seat post that is inserted into a seat tube made
of aluminum, titanium or steel. Do not grease carbon
seat posts and/or carbon seat tubes in the clamping
area! Use special carbon assembly paste instead.
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 the chapter “How
to use quick-releases and thru axles” or by turning
the seat post binder bolts clockwise in half turns.
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.
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? 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.
