mass repartition between rear and front wheel

I am seeking information re. the mass repartition between rear and front wheel and how it is changed by the position (triathlon handlebar) and the slope during climbs.
Thanks and ride smart :)

Ok and the point of this thread is what? That you read something? What is repartition?

Mass/weight distribution?

I think the OP meant Mass(weight) distribution.

I think the standard distribution mentioned is approx 60% rear wheel, 40% front wheel.

With an aero bar set-up the weight distribution should be similar because although the bike will have a steeper seat-tube angle & the rider will be in a more 'forward' position, the distance between the bottom bracket & the steerer axis should be increased. That is one reason why putting aero bars on a road bike is a compromise.

And with increasing upward gradient the weight will shift more and more to the rear wheel. At very steep gradients nearly all the weight will be applied to the rear wheel. At gradients of 90° and greater there will be no weight acting on either wheel.

Mass repartition is defined as follows:

Take the riders weight (W) multiply by the mass of the total frame (TF) multiply by the inverse dampening equation (id.E) multiplied by the overall temperature (OT}.

The whole equation is expressed as:

W.TF id.E OT.
