A Kaesae quote from another forum. Nice one Coffeeking 😆
"I believe that subtle manipulations to the rear end on full sus MTB frames can improve both the efficiency and subsequent ride quality. On the frames I sell and with the bearings my back ends run, energy is actively being absorbed by the action, as there is less energy for the dampening unit to deal with the whole bike performs better.
Look at it this way if a proportion of the energy that is created when the back end moves is absorbed by the actual back ends action then the shock is better able to do its job. As long as this process doesn’t interfere with the movement of the rear end or shocks dampening there are benefits to be gained.
Say we have 100% pressure or energy in the transfer of movement from wheel contact to shock. With standard bearings there is no energy absorption and also as a result of the loose tolerances play either from the beginning of the bearings life or later on. The rear end will move on a very slight arc, and is therefore not as efficient at dealing with these forces that are being applied to it.
However in contrast my bearings or teflon thust spacers and other mods actively absorb energy without interfering with the function of the back end or the shocks dampening characteristics.
How could this not be a good thing? That said the proof is in the pudding" 😕
What a load of b%^*+X
Kaesae, I will try and simplify this. I am no expert, but I think you need help.
Here goes:-
If your back end is nice and smooth & slick (with your SPECIAL PERFORMANCE bearings) then the shock has MORE work to do.
If your bearings are stiff or siezed, then your frame and wheel will take a fare share of the shock because when it takes a hit sha**ed bearings don't allow the shock to do its work.
SIMPLES 😕
