My Specialized road bike is a 52cm frame and I love the way that fits me for road riding.

On the WRIST question . . . well, this Sirrus X model 4.0 which I just bought has the Specialized suspension stem / headset called Future Shock. It grants some minimal suspension and I'm glad to have it but it's NOT the same cushioning you should get from a suspension fork.
I rode yesterday on a 45km rocky / gnarly gravel ride and yes I could have benefitted from a suspension fork for my wrist, which is healing from a sprain incurred by recently crashing on my road bike.
My injury is minor and temporary, so I do not yet have long-term concerns about my wrist. However, if your wrist is always going to be at risk to riding stress, yes I would consider a suspension fork.

Canyon Pathlite was my alternate choice bike, it has a suspension fork but my sizing has not been available for several moths and the avail date per Canyon website keeps moving later and later, so I bought the Sirrus X.
