Speaking of Brakes
What struck me as weird is that we have pro racers putting hydraulic disc brakes on road bikes in pro races. These things are incredibly powerful and can easily lock wheels especially in less than perfect traction conditions.
In the meantime Campagnolo Record skeleton brakes have reduced their power on the rear brakes by going from a double pivot to a single pivot rear brake mechanism. Ummm, aren't we at odds here? |

Rear gives directional stability... balance.

Campagnolo also has road discs- the new Ergos can run caliper or hydraulic disc. Regarding calipers, Campagnolo single pivot rears are lighter than DP yet sufficient to skid a rear wheel. Sensible format IMHO. My Redline aluminum cross bike has hydraulic discs on it and I would MOST definitely not get them again. That bike probably weighs about the same as my Colnago Dream HP which is the lightest of the series at about 19 lbs. Crashing down a hill a brake as powerful as a disc is asking for trouble. Caught out in downpours I never had the slightest problem with rim brakes and listening to people talking about going deeper into a turn before having to put the brakes on makes me wonder if they think that they are world class MTB racers. |

We heard your description of a riding performance go no go once before... I forget what....some time ago...n had the idea you were moving slowly. During my peak years 2 of us covered the county with the Pelton doing race work...15-20 My co rider was Hungarian pharmicist. |

Sensible format IMHO. Are single pivot brakes actual less powerful then dual pivot? I had always assumed that the ratio of the length of the arms on the cable side of the pivot and the brake pads end determined the "power" of a brake. Although admittedly I never gave it much thought other then single pivot brakes seemed more difficult to get "centered". -- Cheers, John B. |

I read that TdeF riders and their ilk have been known to descend at speeds of 100kph using rim brakes. I wonder whether if they had Joerg's vaunted disks, would they be faster? -- Cheers, John B. |
