I'd like to sell the Shimano 105 components that are coming on my new 2010 bike on ebay and purchase Sram Rival instead.
Since my shimano parts are coming off a frame (well, the bike will arrive unassembled in the factory box, so I'm not sure if most of the parts are on it already), what can I expect to receive on ebay for them? What will buyers need to see in the description to know they are getting what they want? I'd prefer to sell as a whole group. Is there any difference between OEM and retail (aside from warranty loss?)
Then..when I go to buy the sram rival, what do I need to pay attention to?
I've bought & sold on ebay many times, but never for anything bicycle related.
I know next to nothing about bike mechanics.
