I bought a used bike and a few months later the cranks started wobbling quite a bit no matter how much I bolted them on there...found out that the original owner or bike shop installed the cranks improperly. I was hoping the bottom bracket was OK...it wasn't.
Just got a new FSA Megaquad BB, some 'Trekking' cranks from Nashbar, and replaced my old chain with a SRAM 971 while I was at it. I kept my rear cog but cleaned the hell out of it, other than that it's all new. I also tuned the front and rear derailers for a couple hours last night, and readjusted my seat height.
Man, it's like a whole new bike now! Maybe it's all psychological, but I seriously felt like 2-3 MPh faster today. The new drivetrain shifts instantly (it's especially better up front), it has to be more efficient without the wobble, and the re-tweaked seat height is more efficient on my legs (it was about an inch too low for some reason, maybe it 'sunk' into the frame slowly over the past few months).
That was a fun ride this morning - when I got to work I was tempted to just keep going :)
