Saddle Adjustment - Diamondback Bike Owners Manual & Assembly Instructions

sADDle ADjustMeNt

there's no hard and fast rule for setting up the riding position on a bike. the
best starting point is to set the saddle height so that you can get the ball of
your foot on the ground while you're sitting on the saddle.
when you have to raise the saddle, don't lift it any higher than the limit mark.
there's a danger that the seat post will break or fall out of the frame if you
do. fit a longer seat post or buy a bigger bike if you need the saddle higher
than allowed by the limit mark.
there is also a fore-and-aft adjustment but you must only move the saddle to
another position along the parallel section of the saddle wire, marked by the
arrows below. don't try to force the saddle any further in either direction or
you'll break the saddle clip. Be careful also when tightening the bolt under
the saddle or you'll damage the alloy threads.
Saddle height adjustment
1
to alter saddle height, undo the
seat post clamp bolt at least two
turns. then work the saddle from
side to side as you lift it up or push
it down. finally, check that the
nose of the saddle is in line with
the top tube and re-tighten the
clamp bolt.

A quick release seat post clamp
must be tight enough to hold the
seat post in place on the roughest
terrain. with the quick release
lever fully open, tighten the
knurled nut as far as you can with
your fingers, then undo it one full
turn. next, start to move the Q/r
lever.
start with the saddle right in the middle of the range of adjustment and try
a short ride. the main thing is to find an easy and comfortable reach to the
handlebar grips. But this also controls the angle of your body, so experiment
by moving the saddle a centimetre at a time until you find the best combination.
check also that you've got a good view of the road ahead, without cranking
your head back at an uncomfortable angle. As for saddle angle, keep it more-
or-less parallel to the ground.
if your bike is fitted with a shockpost that moves up and down to absorb
bumps, adjust the saddle a little higher than normal to allow for your
own weight. if you find that the shock post hits the bottom of its travel
quite often, even after adjusting it, your diamondback retailer will
supply you with a stronger spring, which should stop that happening.
different springs are easy to fit - just undo the adjustment screw all
the way.

it should be easy to move at first,
then harder as the lever gets
nearer to the frame, then easier
just before it hits the frame. turn
the knurled nut anti-clockwise if
the lever is too tight to reach the
frame and the other way if it's too
loose.

when altering the height of the
saddle, you must not pull the seat
post out any further than the limit
mark. if-you do, there's a danger
that the seat post will either break
or fall out of the frame when riding
over rough terrain.
