Like MichaelW, I would like to advise you to be cautious.

Your inseam and the frame size might be close, but that is NOT how bikes are fitted.

It is true, though, that there are several formulas for calculating the 'optimum' frame size from one's inseam. But there are numerous other factors to be taken into account. Try a search on this Forum and you will undoubtedly get numerous, informative, contradictory, etc. results.

The bike's specifications certainly are impressive. It might even be a very good deal. But if the bike does not fit you, you are only doing yourself a disservice!

Believe me. I bought my first road bike from a non-specialised (or overly commercial) LBS. After four years of ever more intensive riding, and suffering (back, neck) and blaming myself for it--it turned out that the bike was just way too small and there was nothing in terms of swapping components that could be done to make it better.

With a little help from an expert, some reading and--not unimportant--my own experience and wishes, I was able to make the transition to a better-fitting bike.

Good luck!
