So everybody knows how much you think about everything leading up to your big race(equipment, training, nutrition etc. ) but most people forget about what to do to your bike after the race.
There are only a couple of things that should be done, but if they are done as soon as you get home after the race it will keep your bike running smoothly. The first thing to do is wash your bike. Make sure you get all of the gels and drink residue off of your bike. If you let all these gels and liquids sit on your bike they will cause rust and can affect the finish of your bike if they are acidic enough. The last thing to do once you have lubed your chain is to switch back to your training wheels and readjust your rear derailleur to the wheel.
Once this is done you are ready to start riding again without any mechanical issues.
