I still ride my rim brakes RB, do you?

Wheels of Happiness

I still ride my rim brakes  RB:   A VV S works and F10 Dogma.  One has Chris Froome symbol of hippo.   I still think rim brakes are great.  Anyway, somebody said (Merck) that to win you have to move forward, not brakek/stop.

The only reason why they are promoting disc brakes is for more peoeple to:

     1.  Buy new frame
     2.  Buy new more expensive Hydro GS,
     3.  Buy new rims with disc.  

I have disc brake powered MTB.   with narrow 29 tires.

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.

How to save up to 74 watts on tire tech

Wheels and tires make a lot of difference in biking (as in Formula car racing)  Here are some tips from a video and may be if we want to ride faster, we can implement some of the tips and suggestions

There is not much advantage/loss/gain on the following:

      1.  Tire weight
      2.  Tire width (which is better 23 mm or 25 mm?)   From competitive cyclist
      3.  Clincher vs tubular?
   

But much can be gained from:

     1.  Tire pressure  (if you are riding on rough roads inflate your tire to only 60 psi, on smooth concrete or asphalt only 100 to 120 psi.  Wrong tire pressure can make you lose power.  This was aptly demonstrated by a rider in Paris Roubaix race who just inflated his tire to 60 psi on cobble stones and was way way ahead of his competitor

     2.  Tire compounds  you can save as much as 27 watts on modern tires with graphene compounds or cotton  inside.  (the graphs show even more)

     3.  Tire rim combination  (it is better to have wider tires and narrow rims)  They are more aerodynamic

     Observance of science and physics can make you go faster.
