REAR HUB DESIGN - large DS bearing?

[kavitator]

Is design with large DS beraing around freehub good or bearing wears too quickly?

It's good. Spaces the bearings more widely, which is good for minimising loads. Allows a bigger bearing, which will take a higher loading (so should increase life).
Only problem is, getting to the pawl/freewheel mechanism!

What about new design Alchemy ORC UL or Easton?

Sam stiffnes and lower weight or less stiff hub?

For big bearing on freehub body i hear they wear out quickly - or i am wrong

Not familiar with either of those hubs.

But a larger bearing doing the same job should last longer. And by the looks of it, when you are pedaling the bearing won't be don't anything, as hub body and freewheel will be rotating at the same rate.

On the down side the bearing is more exposed, so you could get degreaser/chain lube/grit into the bearing more easily.

Both of those freehubs referred to in the link are for the same hub... The one on the left is for SRAM's XX1 11spd 10-42t cassette which requires a different mounting arrangement, dubbed 'XD' and is an open design for manufacturers to use.

Picture i post is just for info -

Wich design is better - new like Alchemy ORC UL, Easton ECHO... or with outer freehub large bearing (older Alchemy ORC)?

Looks like an Industry Nine hubs older hubs. I have those and they are highly reliable rear hubs!
