Sram Force Brake Blocks
I have a SRAM Force on my bike with Reynolds Solitude wheels.
When braking with the front brake, it 'judders' - seeming to have uneven braking grip at different parts of the rim and the pulsing of the braking force makes the front forks bend backwards/forwards in an alarming way. Braking with the rear brake is progressive and smooth. I switched my solitude front wheel onto a friends bike with Ultegra brakes/blocks and there was no pulsing and braking was progressive and smooth. Also, rather surprisingly, braking with their front wheel in my bike worked smoothly and progressively. Therefore, there seems to be some braking issue with my set up that might easily be solved by using Shimano brake blocks. Does anyone happen to know if I can fit Shimano road (105/Ultegra/Dura Ace) brake blocks into the SRAM brake cartridges or will I have to buy a the Shimano cartridges and brake blocks? Thanks, Mark |

No idea, but your description suggests to me that you may have contamination on the rim. Before spending money, try giving the rims and blocks a good clean and degrease. It may solve the problem at zero cost. -- Paul Boyd http://www.paul-boyd.co.uk/ |

Why don't you ask your friend if you can borrow one of his blocks and see if it fits? |

contamination on the rim. *Before spending money, try giving the rims and blocks a good clean and degrease. *It may solve the problem at zero cost. I have already tried several methods to clean them. Both a scotch washing pad and degreaser had no effect. Cif cream on the other hand did ease the problem somewhat after a lot of rinsing - but it has returned as a result of some very hard braking doing La Marmotte last weekend. |

Are your rims made from CFRP? \\paul -- Paul M. Hobson ..:change the f to ph to reply:. |
