Chainstay part of frame stretching?
A mechanic told me he thought my frame where I do up the rear thru axle had stretched a bit because when he tightened the thru axle he could feel the frame coming in a bit. Have you heard of an under-tightened thru axle causing the frame to spread out a bit?
He seemed to believe ideal torque was going as hard as he could go with his mini tool. Stretching the frame at that portion sounds bad to me as it could lead to premature fracturing.
One of the reasons I've been messing with that portion of the bike is that when I go down hills and do any cornering, I'm hearing disc rub. Someone said they got this when their thru axle was overtightened, and conversely it could happen if the axle is done up too loosely, so I'm been experimenting, but I'm really not noticing a correlation: the rub at those times is still there, like quick tick sound of engagement of the pad against the rotor.
To avoid confusion, max torque for that axle is 11 NM, so not very high.
