Not nearly enough to cover the cost differential of a refit with a shorter stem and trying different bars.RyanM said:I'm thinking of selling my 2008 Madone 4.5 size 56. I need a smaller bike (54). Bike is in perfect condition with less than 500 miles on it.
Paid just over $2k for it new. What do you think I should ask for it?
Before you sell a nearly new 2 year old bike that you will be lucky* to get 75% of your cost back, have you considered getting a fitting? 2 cm is easy to fix with how the bike is outfit, especially if going from a 56 to a 54. (*and I mean very lucky)
As to your specific question, not enough information to answer...pics would help, plus condition of consumables (tires, cables, chain, cassette) and what else are you selling with the bike: saddle, pedals, etc.
ebay or craigslist are good places to find comparable prices too.
And lastly don't forget that some of your initial cost for the Trek is due to its lifetime frame warranty. This warranty is not transferrable, and so, at least to me, makes Treks somewhat undesirable for 3rd party private sales, unless the price is really good (ie low).
