When replacing a punctured tube, make sure you cannot possibly mix up the new with the old. I did this on a freezing cold rainy night, with a rear puncture, bolts not QR axle then, bike was laden with heavy panniers, tried to rush it and managed to refit the old tube. You don't fall for this one again in a hurry!

If you snap your QR back axle, don't take all the spacers and nuts off before replacing, it's then much harder to work out the spacing (also don't put the freewheel back on until you have tested the wheel in place).

And remember, hindsight is always 20/20. Live, learn and share.
