Hello. I've got truvativ powerspline bb on my bike with truvativ isoflow crankset, 22-32-44.
I have read up on problems with this setup and several others have experienced my problem: my left non-drive side crank comes loose if you breathe on it and now I fear I have alignment issues due to riding with the loose crank (during the time I didn't know it was loose).
I've attached some pix, pls. note the edges of the splined bb, some deformation appears to have taken place and the edges are rough to the touch. I'm guessing this is causing the crank to come loose even faster than before, vicious circle...
1. Any way to keep the crank firmly affixed considering the damage? I'm guessing the deformations at outer tip of splines are allowing play, no matter how much I tighten down. Blue loctite?
2. Anyone know if SRAM ever recalled the Truvativ ISOFlow MTB crankset? (I ask this question b/c others have asked it before and I never found an answer. I've got a call in to SRAM)
3. Why is the outer area of the crank hole threaded (see pic) when the bolt that affixes is completely smooth where it contacts those threads (see pic)?
