..... bugger .... jsut when I get all enthusiastic about doing some riding in the evening the bottom braket goes. makes loud creaking noises in the same place as it is rotated and I can feel the jump as it overcomes the resistance. now this is expected after much use but the thing is this was a new bike I bought around 8 years ago on which I have probably done about 500 miles and has been standing indoors the rest of the time. AND it is bloody ultegra too!!! not happy at all. why would the BB go so soon? they are sealed so no moisture would have gotten in .... It is one of the splined BB so I would need specail tool - is there a knack to removing the bolts? I think it has the self-extraciting ones but not sure. will take a look tonight and post piccies if I get stuck.
