question about removing octalink crank arms
Do you need a gear puller? I removed the retaining bolts, but they're stuck on there. It's a specialized rockhopper 29.

Mission accomplished! My local REI store had the tool and the mechanic was nice enough to remove the bottom bracket for free.
I love REI! |

My Octalink cranks have always had self extracting rings; all you have to do with these, with the self extractors in place, is unscrew the bolt and the crankarm will back off the spindle.

crank usually dont need to be removed for shipping but you can install self extracting caps from various manufactures

I don't have this on my Octalink cranks. Can these self-extracting rings be retrofitted into what I have? It would make it easier to break down my bicycle for shipping when I tour.
In general, most people don't remove the cranks when shipping a bike. Taking off the pedals is all that's needed. |
Thanks for the information and cautionary note about the "self-extracting" crankarm bolts. I've never had to remove the cranks for shipping but I now have a bike with S & S couplings and am experimenting with how to pack it as compact as possible.

....... the issue with "self-extracting" crankarm bolts is that people rarely tighten them enough. Once the crankarm gets loose and the machining at the spindle interface gets boogered, it's all over. You have to replace the crankarm........

I've never had any problems with Octalink self-extracting cranks, I'm not getting what you're saying. The extractor ring is a a separate piece from the crank bolt; it needs to be snugged down against the crank bolt. How does the self-extracting feature have any affect on how tight you tighten the crank bolt?
