Rotor 3D Crank noise

[Johan Malherbe]

I have a twin blade 3D rotor crank and it started emitting a creaking noise on the pedal stroke. The left pedal more so than right. Stripped rings and pulled BB, lubed cups, and copper slipped q bolts. No avail, still there. Noise emits between spider and pedal arm. Any solutions here?

One area that could still be the culprit is where the crank 'spider' fits onto the blades. There's a special tool that can tighten it. Ask your bike mechanic.

Good luck.

Silly idea: make sure chainring are fattened... Put a little grease between surfaces.. Loctight on all bolts...

 

I had a crank like this for 2 years... Not an issue

 

Good luck

Have you checked the pedals?

Did just that, noise still there.

Checked pedals, no problem there, chainrings no problem there...special tool to tighten up spider seems to be the trick. Anyone knows where I can source tool in Cape Town area?

take the QR scewers out of both wheels, clean and grease and put them back... Sounds crazy, but do it.

Hmm I'm a bit of a noise geek, and assure you that is where I first started...not there. In Crank it is. Think I got it now.

I had that .... in the end I loosened it, put some loktite, retightened and since then it's been OK.
