    Medium sounds about right, but only you know if you are too big.

    Im 6'1" and test rode a medium Reign because a large wasn't available. It was only marginally too small for me, should be spot on for you unless you have freakish proportions.

    Medium sounds right. But if your 5'9" is in some weird proportions - long legs or body or arms or whatever maybe you are on the upper end of the scale. Why do you think you are too big for it?

    I'm 5'9" and ride medium Giants (hardtails), off road that size is spot on for me, on road (rough roads) I use a large for a more stretched out position.

    A quick check suggests the bike has an inline seat post, so you could fit one with a setback to see if that helps (increased cockpit length is the same as going up a size, 20mm - or you could just try sliding the saddle back on the rails).

    About 5' 10" and have always ridden an 18" frame, that's classed as medium.

    Mines also 18" and that's large.

    17'" > 18" = M
    19" > 20" = L

    Not any more. Seat tubes have got shorter and top tubes have got longer. Most large trail bikes have around an 18" seat tube, dropper posts have changed things.

    Well, in that case, if it has changed then you would be right.
    Newest bike I have is 13 years old. :lol:

    Take a look at modern trail bikes. Seat tube length has become irrelevant. They have shorter seat tubes to allow the extra length of a dropper post although for riders with long legs it can cause problems.

    It has been irrelevant for quite a long while, my 1985 custom built MTB has a 14" frame and I have the saddle set at 34" from bottom pedal.

    One would have thought that this way of measuring an MTB would have died after 30 years of discussing it, but it still endures.
