Hello all - would any of you please be able to advise on what would be involved, and how easy it would be, to change the 52X39 front chainrings on this bike (Specialized Allez Sport 2007) to a compact (50X34) for getting up hills a bit more easily? Also, what would the costs involved be roughly? It currently has a Shimano Tiagra Hollowtech II 2-piece crankset, and a Shimano Tiagra Hollowtech II bottom bracket. ... oryID/136/

I am a cycling newbie so don't have much knowledge regarding this type of thing - thanks very much in advance!
