Challenges with my Carbon Fiber wheelset

I have troubles with my Bora carbon fiber wheel set.   The bearings are toast and I have to replace this.  There is a humming sound when free wheeling.  The mechanic confirmed this.  I have to find out the bearing number.

The other one is the rim is worn out.  I used the wrong brake pad and the pad has eaten into the rim.  It is good that there is someone in a town that specializes in carbon wheel repair.   I hope he can do the job.

If it is too tight, it is difficult to pedal and drive the bike, if it is too loose, the wheel wiggles from side to side.  It is challenging to get this right.    Sometimes the tighter tightening of the QR can solve the problem

This post had a difficulty with an old seatpost.   The serrations  at the top of the seat post and the semi half moon at its top had worn out.  Thus no matter how you tighten the nuts and bolts, the alum parts keep slipping.  

The solution is to restore friction between the bottom and middle part.   How do you restore the friction
So this post disassembled the seat post and tried to restore the reaming.  All that was needed was a thin screw driver to retrace the reaming.  Patiently, this post did this for the bottom part and the half moon insert.   

After an hour, this post was done and the seat post restoration was complete

Testing this afterwards resulted in tight and non moving saddle.  Perfect
