About a month ago, my peloton developed an intermittent clank that ultimately worsened over time. Last week I was in the middle of a ride when the pedals/crank locked up on me out of nowhere. No matter how much downward force/pressure I placed on the pedals, the cranks would not turn. Fast forward to today, I was finally able to get the crank arm and pulley off, and to my surprise, it looks like the bottom bracket is the culprit. Am I wrong for assuming the part that is chrome/shiny was once attached to the right crank arm? I cannot find any images of the Bike+ right side crank arms to see if that is the case? Need help figuring out what I have to buy to get it up and running again.

I am also considering purchasing an aftermarket bottom bracket since these Vortex ISD-12's are notorious for failing.

I've managed to answer my own question(s) after further tinkering... The chrome ring (once powder coated black, worn to bare metal) is the lock ring for the (right side) bottom bracket. I questioned whether that part attached to the right crank arm and learned it DOES NOT attach. It is a part of the bottom bracket. It appears over time the lock ring loosened (indicated by misaligned paint marks), causing it to come into contact with the right crank arm/pulley (orange wheel). In addition, it looks like tons of shavings may have gotten into the bearing and seized it.

If you see the inside of the orange wheel (technically black part) there is severe marring from where the loose lock ring came into contact. I still have to lean out the threads on the frame but I am fearing the movement from the bottom bracket may have damaged the threads... which would mean a new frame is in line :mad: I am praying that is not the case but we shall see...
