cant trust the bike shops

i rocked up at the bike shop i normaly go to and said my bike has abit of a viabration he had a look over it and said it was my chain and i needed new sprockets and chain so yer ok do it friday (it all looked fine to me) so i rock up there today and he said oh they didnt have the stock size but they had these other ones and i so i asked what size they were and he said 49 on the back 17 on the front so i was abit pissed that he didnt ask me b4 he got them in he got half way though and i worked out how different it would be and i said forget it just to show how this would affect it i will do the math

so stock is 16 front 39 back

16 front 39 back = 1
15 front 39 back = 1.0666666667
14 front 39 back = 1.1428571429
17 front 49 back = 1.1825037707
13 front 39 back = 1.2307692308

i so glad i didnt let him go ahead with it

He probably had those sprockets and couldn't get rid of them...and figured people who go "rocking" from place to place are morons...I would have put those two together, as well.

I would have figured that someone who went "rocking" from place to place was from another country. Well....what do you know.... I'm right.

I'm fortunate to have a bike shop I can trust, AND a sweetheart who can do anything.

Robert Persig talks about this type of event in his book Zen and the Art of Motorcycle Maintenance.  His narrator describes the moment he began taking the maintenance of his bike into his own hands.  I'm paraphrasing, but the mechanic in the book sheared off cooling fins and punched through the crank-case cover in his attempt to "fix" the bike.  The narrator eventually stops the bike shop guys and fixes the damage himself.  Although I've read the book many times myself, I re-read it this summer while healing up from surgery.  It inspired me to learn to do things myself on my bike.

Us Aussies are the king of rock!

Thats why we built a memorial to it in the middle of our outback and named it Uluru!
