Serously, I'm a small frame on a specialized Sirrus ?

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.

The Geo chart on the special says get an S sized frame, not the M

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.

yeah, I need to measure and revisit them bikes

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.

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?

Size M by the way, standover a smige high but nothing I can't deal with.
