I have a strange predicament.
I decided to install longer cranks on my QU-AX Profi, which comes with an Isis hub. I used my Park ISIS crank removal tool and removed both cranks fairly easily.
The predicament is, on the right-hand side of the hub there appears to be something stuck inside the hub, where the crank bolt would normally thread into. I’ve attached pictures, but I have no idea how the original crank bolt was threaded in here to begin with.
I removed it like I’ve removed all bicycle cranks over the years; I removed the crank bolts, threaded the crank remover into the socket in the crank, tightened it, and then cranked the internal bolt into the removal tool to force the crank arm off of the isis spline.
It worked fine, but when I went to thread the new crank arms into place I noticed that I couldn’t get any thread engagement on the right-hand side, and then noticed this barrel of black metal inside the thread housing. It won’t come out and I have no idea where it came from.
Is it possible that the tip of my crank removal tool broke off into the crank arm? Any other theories? Is there something strange about QU-AX Isis hubs? Should I try a bolt extractor or something? Any other ideas for how to fix this?
Thanks in advance for any help or insight!
