Advice needed for cranks that use self-extracting crank bolts for Campy 9 spd
I have bought an S & S coupled frame and need to add a crank that will
easily come off when I want to pack it up. I usually use Campy triple cranks as I am running Campy 9 spd but I could go compact or some other brand in a triple if it worked better. I already stripped out a Campy crank when the add-on self-extracting bolts self-destructed and wiped out the threads on the crank. Any thoughts about a good way to go that is reasonably priced? Any triple cranks that come with self-extracting bolts? Thanks, Alan |

Any triple cranks that come with self-extracting bolts? Thanks, Alan Can you find a case that will accomodate with the crank arms with pedals off? Constant removal of what is an interferance fit of sorts is not likely to be good for the soft aluminum. Assuming you keep your current set up, I'd try to figure out just what amount of torque you need to put on bolts to affix them so your removal forces are not so hard on the self extracting bolts. I don't know if a splined crank assy still exists but you might be a candidate for that.

This might be a good application for one of the new two-piece cranksets, such as the "10-speed" Ultegra.

The cranks on my travel bike need to be removed to pack it in its suitcase and they've been on and off a few dozen times without any apparent harm. They're the old '8-speed' Ultegra with square tapers and self-extracting bolts. |
