ParkTool, self-explanatory).
10. Squeezing an aluminium frame in a repair stand clamp. (this hurts just to type it
)
11. Mounting Shimano pedals on a full Campy bike (just kidding
).
ok, who's turn?
Don't:
Pump up a tire to full pressure without checking to see if it is seated on the rim.
Try to grab said tire as the tube bulges out from under the bead.
Try to deflate said tire while the tube is bulging out from under the bead.
