you have a ride organised for the next day ,early start 30 miles away . Your bike has been performing flawlessly for weeks so what do you do ??
You decide to change the bars and stem of course.
Not satisfied with that you realise you'll need to put new tape on the bars so you might as well upgrade and put the new STi shifters on you have been saving for weeks....Fantastic
Of course that will mean changing the chain and as the bottom bracket has been creaking for months you might as well put the new bottom bracket and chainset on you have been meaning to do for ages.
If you are going this far you might as well put some nice new cables on as well.
Lemmesee now the only thing I'm not changing is the seat post
might as well change that as well then...
Its 8.30pm and I've just got the computer left to put on and hopefully it will be finished.... phew
