OBTAIN THE CORRECT SADDLE HEIGHT

STEP 1

Check that there are no washers inserted in the seat clamp. If so,

remove them.

Determine the length of the section that needs to be cut off.

The length of the cut-off section equals the saddle height before cut (HBC) less the correct saddle height (CSH). Cut-off length = HBC – CSH

The CSH is the measure you want between the top of the saddle and the centre of the bottom bracket.

To get the HBC install the saddle (without washers!) and measure the length between the top of the saddle and the centre of the bottom bracket. Note this measurement.

To know the length of the section of the seat post you need to cut off to reach the correct saddle height (CSH), just apply the formula above.

STEP 2

Loosen the saddle clamp bolt and remove the saddle.

STEP 3

Mark the precise location of the desired cut. Make this mark one or two millimeters above the precise location because it is possible to reduce the height later (if necessary) by using a file. This is also a more accurate way to reach your desired seat height.

Be sure to double-check your measurements.

Be sure to double-check your measurements again.

The length to be cut = HBC – CSH

Example: CSH = 75.5 cm HBC = 78.0 cm 78.0 – 75.5 = 2.5 cm

– 2.5 cm is the length of the seat tube that has to be cut

STEP 4

Put the seat tube in a horizontal position. Make sure your cut is exactly perpendicular to the integrated seat post. Move your saw slowly and smoothly.

ATTENTION: To avoid fraying the composite fibers, we recommend using a fine tooth saw blade (32 teeth per inch / 12 teeth per centimeter).

CAUTION: Be sure to wear appropriate safety equipment, such as glasses, gloves and a dust mask. Do not inhale any of the dust!

ATTENTION: Be very careful at the end of the cut to avoid splintering the material.

STEP 5

Carefully sand down any burrs with fine emery paper. Clean off the dust with a damp rag and discard it immediately.

STEP 6

Install the saddle onto the seat post. Make sure to follow the installation instructions provided by the manufacturer of the frame and the saddle.

ATTENTION: tighten the saddle clamp bolt using the recommended torque to prevent the saddle from slipping and to prevent damage to the clamp or to the seat post.

FINELY ADJUST WITH WASHERS

STEP 1

Remove the saddle.

STEP 2

Select the correct size washer.

There are two choices: 10mm (1pc) and 5mm (1pc).

STEP 3

Put the washer into the saddle clamping mechanism.

STEP 4

Install the saddle on the seat post.
