Do Not Buy Broken Carbon Frame!!!!!!!
I am shocked the LBS is trying to sell a cracked carbon frame. IMHO, this should put all of their advice into the 'suspect' files. This shows extremely bad judgement.
Wow. No no no no no. Do not buy. You can get a nice steel or decently lightweight aluminum frame for cheap.
The bike shop needs to saw the carbon frame in half and throw one half in the garbage before they change their mind.
Wow. Holy krap. Bad idea. Yikes.
