A change of parts pushes you for more repairs and improvement; NB DO NOT WADE YOUR BIKE IN THE FLOODWATERS NOR WATER THEM HUBS WHEN CLEANING

Wheels of Happiness


After I installed the CY rb tires, I experienced difficulty with its continuous rotation, Theres seems to be a bike rub.  Solution.  I tried reinstalling and centering the wheelset with the weight on the wheels.  The problem was solved.

This post then regreased the:  sealed hub bearings.  They were last regreased 6 months ago.   Now the bearings are as good as new  Maybe they will last for the next 10 years.

Just avoid wading the bike in flood waters.  Or watering the same when cleaning the bike

Removal and reinstallation of sealed bearings

Conversion of ball bearing to sealed bearing in a Deore hub

Wheels of Happiness

I have been thinking of converting from ball bearing (as is often with Shimano hubs) to sealed bearing.  They say it is longer lasting, less prone to bearings getting loose, and getting grit, and affected by water causing their early failure.

The sealed bearing number is RS 6000.

The challenge are with the axle.  4 options:

1.  A anew axle with stopper for bearing (that should fit RS 6000
2.  Put nuts inside the old shimano inside as bearing guide and stopper.
3.  Put a tube shim inside;
4.  Do nothing with the axle.  Just hand tighten the outside cones.

What do you think?   Choose 1 or 4.

Better more advanced features of the carbon wheelset with Bora sticker that I just bought

I compared the Cosmic 50 mm wheelset that I got 5 years ago that came with Fuji SL from VM with the recent acquisition that I got from an OEM supplier.   It is a Bora Ultra copy  and its features are:

1. Solid carbon construction.  It has carbon brake line and pad (I had to replace the Shimano rubber lining with Basalt pads brown)    The cosmic wheelset has only paper thin carbon cover 50 mm in width between the aluminum brake line and the spokes line.  You can press the carbon cover of Cosmic and will be pressed down upon your touch

2. U shaped rim spokes line vs V shaped for Cosmic.  According to the pitch this makes for better aerodynamics less dirty air and better crosswind performance.

3.  25 mm side rim vs 17 for Cosmic.  Thus when you install 25 mm wide tires, the tires really look big and massive.

4. Nice authentic stickers.... Bora Ultra 2

5. Great looking carbon R36 hubs. Noisy too....

6.  Lightweight.   Mere 1.6 kg.  (vs 1.4 kg for the orig) hehehe.

For me it was money well spent... Great looking  with Pinarello F10 frameset
