this bike works great, a good ride. some one actually used this bike but took care of it. I say this as there are signs of use, skuffs, a few light scratches but there are no issues that would effect function for sure and it still looks good to me! my point is if you are one of those folk who wants to buy it to hang on your wall and look at it--maybe not this one. That being said, however, there is a ton that this bike offers to one who is into performance and function. she got Avid Ti brakes, Easton Monkey lite xc carbon handle bars, Shimano XTR brifters (that work great!) XTR cranks -tho they are worn, both the shocks work the front is Rock Shoc SID Team, the rear is Fox Racing shox Floatr with Specialized Brian. Sram GX rear derailleur

if you want close ups of something or measurements let me know. I prefer to answer questions rather than an unhappy customer.

please no ALaska or Hawaii.
