Hi! New to the forum that I've been reading for years.
I have an old panasonic frame which i built up to my first fixed gear. I've been riding on it for about a year and i've only recently noticed that my bottom bracket keeps getting loose.
Both cups are tight, i've put sufficient torque on each. But after about a mile of riding my bb keeps loosening. The wiggle is horizontal and at the bottom bracket, NOT the crank arms. I've tried everything, including teflon tape. The frame threads don't seem to be ruined, but if anyone has had a similar problem or has some recommendations that'd be awesome. Thanks!!
