Looking to buy a Reverb but I’ve confused myself regarding sizing.

My bike is a Trance X3 (L) and I’m 6ft. I’m only able to insert 225mm of post into the seat tube due to the suspension pivot. I currently have 200mm of post showing from the saddle rails to the collar at my optimum pedalling height.

Am I right in thinking a 380mm/125mm Reverb is the right size for me and will fit the tube? Many thanks.

125mm is 195mm from bottom of collar to middle of the rails.

380-195=185mm.

By my maths you’re fine with that!
