How do you remove the "spider" from a Cook Brothers crank?
I have removed the little torx screw that held the spider to the crank
arm. I thought it would slip off now; however, it still feels pretty solid. I was tempted to apply BFH, but I thought I'd ask first. Any other suggestions? Jones |

They're *NOT* F-series and they're not "dog bonz". They look like this: http://cgi.ebay.com/Cook-Bros-Racing...QQcmdZViewItem That's a URL that'll go out of scope fairly quickly. It looks like I press it off, but I want to make sure before I bring the 10-ton hydraulic ram down upon it. Jones |

If you're never going to put a spider on the cranks again, then go for it. IIRC, these types of cranks had a reputation for squeaking at the spider/crank joint- if you get it apart, will it ever get together again? OT question- are you related to ? of "? and the Mysterians" ??? Jeff |

I want to mount a double chain ring to act as a tandem timing gear, that's all. I can't get the longer mounting bolt through one of the holes because the crank arm is too close. I thought the spider would pop right off... apparently not! But, if you're not *supposed* to take them apart, then there's a different approach, so your reply is, indeed, helpful. All I gotta do is figure out how to do it without removing the spider. OT question- are you related to ? of "? and the Mysterians" ??? I'm Smith. In the '70s, there was a popular TV series called "Alias Smith and Jones", so I was called "Jones" in Vietnam... but I'm "not Jones". Jones |

I always thought the spiders were easily removed... guess not. Jones |

They're not filling any orders, so I doubt they're offering any customer service. Their site says they're selling bikes; however, I have friends who have tried to get one. CBR just never answers.

I've worked on plenty of "hidden bolt" cranks- that last bolt only works if it's got a track nut on the crank side of the chainring. Holy carp- I remember watching "Alias Smith and Jones". Does that make me an old fogey? Jeff |
