Wow, thanks for all the great responses guys.
The shop hinted that it would not be much, the guy that was working with me at the time was not there, and they did not want to get much into the transaction and the swap without him there (not sure if he is the owner or not). I will talk with them about it this weekend. From what I gathered its not just a simple crank swap, it would be all that has been mentioned. Honestly if its less than 50-75 dollars in labor, than its not that big of a deal, the shop owner does have to pay their bike mechanics, and irregardless, I was going to bring them a 12 pack of beer just to thank them for setting the bike up after its all said and done, crank swap or not. I want them to know me when I come in and maybe treat my baby with just a little extra touch of tlc.
I am still debating if I want the swap or not, I dont see a need for it, then again, whats it going to hurt If I have it?
Once again, thanks for the information and input..
