Saddle adjustment: the BRP

Saddle adjustment: the BRP


Comfort and “setting” the saddle: to obtain the former, or rather comfortable pedalling that guarantees well-being and high performance, the latter needs to be done in accordance with strict measuring criteria.

After many years of studies and findings on thousands of cyclists, Selle Italia has adopted a scientific saddle adjustment system valid for all types of brands or models, based on a biomechanical point of reference and called, precisely, the BRP (Biomechanical Reference Point).

This is essentially a type of barycentre, or rather the median line where the saddle reaches a width of 70 mm, and constitutes the point of reference from which to measure the parameters needed to assemble the saddle itself (height, retraction, distance from the handlebar).

The concept of identifying the BRP is the result of careful observation of cyclists’ behaviour, which revealed a constant: the position of every cyclist’s saddle is always the same distance from the BRP.

This distance is subjective, that is, it differs from cyclist to cyclist.

Following a series of tests carried out in the field however, it was found that 60% of cyclists sit too far forward on their saddle, thus offloading their weight predominantly on the pubic symphysis rather than the ischial bones, which is what should be happening.

This not only cancels out the exceptional comfort that Selle Italia saddles are able to guarantee, but can also generate annoyance and soreness in the pelvic area.

To help cyclists sit properly on their saddle, Selle Italia has developed a line of test saddles with drawn on the cover both the BRP line and another line called the FIT LINE, located 110 millimetres from the BRP toward the tip.

A cyclist is sitting perfectly if while pedalling, the FIT LINE just slightly protrudes past the crotch of their shorts.

If the FIT LINE is not visible to the cyclist while pedalling, this means they are sitting too far forward on the saddle.

This can mean one of two things:

  1. The cyclist is not using the saddle properly.
  2. The cyclist has an unsuitable positioning on the bike.

In any case, if their position is too far forward the saddle should most likely be shifted slightly forward.

To the contrary, if a large space is visible with respect to the FIT LINE, the saddle will need to be retracted to find the right position, or rather the most comfortable sitting position.
