Crank/BB question (possibly dumb) - TruVativ
Picked up about half (frame, drivetrain, fork) of an old GT Avalanche 1.0, and have been putting it together for a friend.
The bottom bracket seems solid, but is unbalanced -- which is to say, with the chain off, it will strongly prefer a specific side down. I was looking at it to try and figure out why, and noticed that the cranks do not go straight across the bearing. This is to say, where I would expect them to be exactly opposite of each other, or 180° across, there is about a 3-5° deviation.
Hopefully I have explained this clearly...
So is it normal? And if so, why?
If not, what could be causing this and how would it be fixed? Nothing seems to be damaged or bent.
TruVativ FiveD crankset (assuming it's a Powerspline BB)
A little reading tells me this is generally regarded as a lower-grade product, but still no explanation of the offset.
