Incorrect saddle placement can cause pain or even physical injury. Adjust the saddle correctly by following these instructions or consult a biomechanist.

Correct height

There are several methods to calculate the ideal height. Here is a simple one that you can do yourself.

Barefoot and with your back against a wall, insert a book between your legs so that while in contact with the wall by one of its edges, you will lift it up until it touches your crotch.

Measure the height from the ground to the top edge of the book (H).

The height obtained should be multiplied by 0.88 and the result will be the ideal distance between the center of the bottom bracket and the top of the saddle (A).

Longitudinal displacement

Sitting on the bike with your clothes and cycling shoes on, place your feet on the cleat and turn the pedals until one of the cranks is horizontal. 

Placing the string of a plumb bob on the ball joint, we will check that it is vertical to the pedal axle.


As a general rule, the saddle must be perfectly horizontal or with a minimum unevenness. In curved saddles we will take as a reference the central area where the cyclist is mainly supported.

Saddle attachment

The seat post should preferably clamp the rails in the center area. Avoid clamping it at the ends as there is a greater risk of breakage due to excessive leverage.

The tightening torque depends on the model of seat post used, but as a general rule it should be tightened sufficiently so that the saddle is firmly clamped and does not move. 

Although the rails are solid and very resistant, excessive tightening is not advisable, in general it is not necessary to exceed 7 Nm (Newtons meter).

Compatible seatposts

All seatposts are compatible except those that do not accept oval section rails. In these cases 8 x 8.5 mm adapters can be used.
