Cannondale Tandem BB Clunk ??
We have a Cannondale MT800 26" tandem that seems to have a problem in the cranks or BB somewhere. When the Captian's RT side crank arm is at 1:00, a clunking noise is heard as pressure is applied to the arm. The more pressure on the crank arm, the louder the clunk noise is. It will do it on every revolution in the same position.
I took the whole eccentric BB apart, greased and reassembled. [It is the single wedge design] Noise was slightly less for maybe 20 miles, but is back in it's full glory now.
Has anybody, by chance, seen this before ?
What may be causing the issue?
BB is octalink if that makes a difference.
Thanks !!
