safe. If your bicycle has such a sight hole, use it instead of

the “Minimum Insertion” or “Maximum Extension” mark

to make sure the seat post is inserted in the seat tube far

enough to be visible through the sight hole.

If your bike has an interrupted seat tube, as is the case on

some suspension bikes, you must also make sure that the

seat post is far enough into the frame so that you can touch

it through the bottom of the interrupted seat tube with the

tip of your ﬁnger without inserting your ﬁnger beyond its ﬁrst

knuckle. Also see NOTE above and ﬁg. 5).

WARNING: If your seat post is not inserted in the seat

tube as described in B.1 above, the seat post may

break, which could cause you to lose control and fall.

2. Front and back adjustment. The saddle can be

adjusted forward or back to help you get the optimal

position on the bike. Ask your dealer to set the saddle for

your optimal riding position and to show you how to make

this adjustment. If you choose to make your own front and

back adjustment, make sure that the clamp mechanism is

clamping on the straight part of the saddle rails and is not

touching the curved part of the rails, and that you are using

the recommended torque on the clamping fastener(s)

(Appendix D or the manufacturer’s instructions).

3. Saddle angle adjustment. Most people prefer a horizontal saddle; but some riders

like the saddle nose angled up or down just a little. Your dealer can adjust saddle angle

or teach you how to do it. If you choose to make your own saddle angle adjustment and

you have a single bolt saddle clamp on your seat post, it is critical that you loosen the

clamp bolt sufﬁciently to allow any serrations on the mechanism to disengage before

changing the saddle’s angle, and then that the serrations fully re-engage before you

tighten the clamp bolt to the recommended torque (Appendix D or the manufacturer’s

instructions).

WARNING: When making saddle angle adjustments with a single bolt saddle

clamp, always check to make sure that the serrations on the mating surfaces of

the clamp are not worn. Worn serrations on the clamp can allow the saddle to move,

causing you to lose control and fall.

Always tighten fasteners to the correct torque. Bolts that are too tight can stretch

and deform. Bolts that are too loose can move and fatigue. Either mistake can lead to a

sudden failure of the bolt, causing you to lose control and fall.

Note: If your bicycle is equipped with a suspension seat post, the suspension

mechanism may require periodic service or maintenance. Ask your dealer for

recommended service intervals for your suspension seat post.

If your crotch touches the frame, the bike is too big

for you. Don’t even ride the bike around the block. A

bike which you ride only on paved surfaces and never

take off-road should give you a minimum standover

height clearance of two inches (5 cm). A bike that

you’ll ride on unpaved surfaces should give you a

minimum of three inches (7.5 cm) of standover height

clearance. And a bike that you’ll use off road should

give you four inches (10 cm) or more of clearance.

2. Step-through frame bicycles

Standover height does not apply to bicycles with

step-through frames. Instead, the limiting dimension

is determined by saddle height range. You must be

able to adjust your saddle position as described in B without exceeding the limits set

by the height of the top of the seat tube and the ”Minimum Insertion” or “Maximum

Extension” mark on the seat post.

B. Saddle position

Correct saddle adjustment is an important factor in getting the most performance and

comfort from your bicycle. If the saddle position is not comfortable for you, see your dealer.

The saddle can be adjusted in three directions:

1. Up and down adjustment. To check for correct saddle height (ﬁg. 3):

• sit on the saddle;

• place one heel on a pedal;

• rotate the crank until the pedal with your heel on it is in the down position and the

crank arm is parallel to the seat tube.

If your leg is not completely straight, your saddle height needs to be adjusted. If your

hips must rock for the heel to reach the pedal, the saddle is too high. If your leg is bent at

the knee with your heel on the pedal, the saddle is too low.

Ask your dealer to set the saddle for your optimal

riding position and to show you how to make this

adjustment. If you choose to make your own saddle

height adjustment:

• loosen the seat post clamp

• raise or lower the seat post in the seat tube

• make sure the saddle is straight fore and aft

• re-tighten the seat post clamp to the

recommended torque (Appendix D or the

manufacturer’s instructions).

Once the saddle is at the correct height, make

sure that the seat post does not project from the

frame beyond its “Minimum Insertion” or “Maximum

Extension” mark (ﬁg. 4).

NOTE: Some bicycles have a sight hole in the seat tube, the purpose of which is to

make it easy to see whether the seat post is inserted in the seat tube far enough to be
