    BIANCHI SPILLO RUBINO help needed regarding frame size..

    hi all, this is my first post on the forum.
    i have recently purchased a Bianchi Spillo Rubino hybrid bike size 51. the sizes available in the store were 47 and 51. according to the store guy, size 51 is a "L" size and 47 is "M". i am being quite tall(almost 6'2") he suggested a size 51. i tried the bike in the store..liked it and purchased it.
    after riding it for a day or two i had a feeling that the bike is somewhat small for me.
    i came across a bike sizing chart which mentions that for a guy of my height, size 55 bike is needed. now after reading that i tried talking to the store guy but according to him 51 size bike is right for me.

    i would like to get some advice from the senior members of the forum if the bike size is right for me or not and also any suggestions are welcome.

    thanx and warm regards.

    The numbers the company use to describe the frame size are not standardized, so any chart or guide that makes a general statements that "a person of X height needs a frame of Xcm" is meaningless. It cannot take into account the differences in frame design between manufacturers and models, or the fit preferences or flexability or expectations of the rider.

    Since you are 6'2" I would assume you want the L or XL of any brand. However, the L or XL of any bike may or may not be a good fit for you.
    There are three ways I can think of to tell if a bike is a good fit for you:

    Get measured by a competent shop that does professional fittings (this can get you in the ballpark, adjustments might be necessary after you start riding)
    Compare it to a previously owned bike that you know is a good fit
    Ride the bike and make necessary adjustments (if you need to buy super long seatpost or weird stem to get it comfortable it may be the wrong size)

    What constitutes a good fit? If you ride the bike on the rides you want to do (terrain and distance) and you are comfortable, the bike fits.

    Seat tube length from Center of BB to top of that tube, is said to be frame size..
    but if there is a sloping top tube , that length is short. relative to top tube length.

    stand over the bike.. ride it out of the shop on a test ride ..
