I have an annoying creak which I think is coming from the crank. As it has the motor, my suspicion is that the bolts retaining the motor may be loose, It runs fine and no other issues just the creak when I put my weight on the pedals.
I have the tool to remove the cranks but I will need to remove the chain rings and spider before I can access the bolts. The chain rings should be straightforward however It looks as if I need a "castellated" spanner/tool to remove the retaining ring for the spider, does anyone know the size and where I might get one? Is this a normal thread or a left handed one? The bike is a 2017 Bulls with a Brose motor but I am nowhere near a dealer so I plan to tackle it myself, what can possibly go wrong?
