Sizing for Advanced Revolt 2

hi all,

i’m looking to get into gravel biking! I have an old 2012 bmc team machine and want to get away from an aggressive bike and have a more relaxed ride. My back now hurts after riding more than 10 miles. (I got a proper fit years ago , but i’m old now)

I have strange measurements so it’s been difficult to determine what bike works for me.

i’m looking at a size M advanced revolt 2 — and would love to swap out the tires for road every now and then.

height: 6ft

inseam: 31 inches

long torso. short legs 😂

previously , I bought a canyon grizl size M and I felt too stretched , hurting my back so I returned it

does anyone with similar measurements have experience with giant bikes? i
