Generic Brakes vs Dura-Ace 7700 brakes ?
RS wrote: I have a Giant OCR1 road bike that came with generic brakes, probably Tectro (?). Being used to V-brakes on my beater bike, I thought the Giant generic brakes were lousy. I put Kook-Stop black pads on them and they do work noticeably better. But I like having very good and controllable stopping power. I can get a used but very clean set of DuraAce 7700 brakes for $70. Will they work noticeabley better? Weight is not a concern as there is probably very little difference. thanks to all Properly adjusted with good cables and Kool-stop pads, I doubt the DuraAces will "feel" any better. However, my own experience with those Tectros wasn't very good. The stock pads they come with are *horrible*, wore quickly and left crap and score marks all over my rims. Then the plastic sleeves between the spring and the brake body broke, and the springs rubbed metal-on-metal. I had to push grease in there every couple weeks with a q-tip. Then the pinch bolt on one stripped under a reasonably low torque. After that, I tossed them a replaced with Ultegra 6500's I got on clearance, no problems since. |

You might want to check the reach of your frame. I believe that at least some if not all of the OCR models are designed to use "long" reach brakes. Not true, use standard reach brakes. Are they in the overlap region where they fit both standard and long reach brakes? According to the Giant website they use "long reach": Aluminum OCR: http://www.giant-bicycle.com/us/030....sp?model=11332 Carbon OCR: http://www.giant-bicycle.com/us/030....sp?model=11251 |

Yes, I should have checked these and they are long-reach brakes. I'm going
to check the cable and save the money for now. thanks In article , whatsupandrewathotmaildotcom says... RS wrote: I have a Giant OCR1 road bike that came with generic brakes, probably Tectro (?).

What Giant calls long reach are actually standard reach brakes, with a reach of 47-57mm. True long reach brakes should reach to around 70mm, like a Dia- Compe 750 Centerpull, or the new Tektro R556, AKA the Rivendell Silver Sidepull. |

Gotta disagree. 47-57mm is a long-reach brake these days. I use brakes of this reach on my road bike, but very few newer road bikes have that kind of reach. The standard today is the compact reach brake; you know, that kind where fenders are difficult or impossible to fit and where a 32C tire is getting way to big to fit under the fork crown or the brake bridge, etc. At least, when you go to buy new brakes today, a caliper that will reach 57mm is called long reach. Tektro 521AG Long-Reach Dual-Pivot Calipers: http://sheldonbrown.com/harris/brakes.html#calipers http://www.lickbike.com/productpage.aspx?PART_NUM_SUB='1314-00' Standard-reach today is around 39 - 49 mm, unfortunately. mC |

I have these brakes on my bike, and honestly they're not mushy at all after lubing the cables and housing. They were horrendous until I did so though. Mushy feelings are usually due to either affection, or the brake pads not being oriented completely square to the rim. Pads without orbital adjustment suffer severely from this. Remember, not all Tektros are equipped with the orbital adjusters. -- Phil Good to know Btw, related: I have a race bike with Chorus 2004 and a training race-bike with Veloce 2004, yet the Chorus feels a lot stiffer. Is that a calipher difference or is that a case of tuning too? |

That's why I had "long" in quotes in both of my replies above. I don't think that was Peter's point because of the Dura Ace calipers that were being discussed. |

I'm going to have to agree with Sheldon that brake that reach 70mm or LONGER like the Centerpull and Tektro R556 should be consider "Extra Long Reach," as less than 1% of all bikes today will need anything that long. Of course, if you are into the 650B (584mm) revival, then you'll need every the "extra" long reach! Then again, I don't get the Centerpull brake thing - ugly, heavy and more difficult to set up. Other than the longer reach, which will now be filled by the new Tektro R556, what's the point? |
