Looking at getting the specialized Sirrus Sport

I'm 5 9 with a 29 inside leg

Past bikes.

Giant Defy 2016 in a M, stand over was 770mm and as high as I dare.

Cube 29er in 17" ... hred-2016/

2004 Trek 4500 in 17" ... 00/details

The Geo chart on the special says get an S sized frame, not the M ... ort/115229

So I tried both the M and S sized Sirrus at the weekend, the M as to big and the S was pretty much spot on, do specialized have wacky sizing ?

    29" inside leg for trousers, rather than measured cycling inseam (feet ~8" apart, book wedged between legs with pressure similar to how it would feel on saddle)?

    I'm 5'10" with ~32.5" cycling inseam (I buy ~30" inside leg trousers), I would choose a medium or perhaps a large.

    My sirrus was a medium and im 5ft 8 with shortarse 28 legs. Unless the geometry changed from 2012/13 id have thought a medium. As per your thoughts a revisit is in order. Personally id look at trek fx or giant or similar or just get a roadbike. I couldn't fault my sirrus other than it was heavy, but at that time i didnt know i was paying for the name.
    Too many bikes according to Mrs O.
  • I'm a very similar hight and my Orro Gold is a small, but fits very well (proper bike fit). I've always been a medium on bikes in the past.
    Never be tempted to race against a Barclays Cycle Hire bike. If you do, there are only two outcomes. Of these, by far the better is that you now have the scalp of a Boris Bike.

    My defy is 770mm

    The defy was close to the limit of what I could comfortably standover.

    The small sirrus is 750

    The medium sirrus is 786

    The Marin Fairfax sc4 and Giant rapid in a M are 750mm standover

    If you've tried, and it fits nicely, why worry about numbers?
