Looking at the 15" size, with it's 22" toptube, sounds perfect for me and what I like in fit. 5'9" with average torso and arms, but shorty legs. But the 22" TT measure is taken with the 25mm setback seatpost, yeah? I'm wanting to use my Gravity Dropper post with the frame - no setback. But it'll leave about 9.5" exposed post at full extension, maybe with the 71* seat tube angle that'll still allow me to get far enough back without cramming my seat way too far back. Am I going to be too cramped? The 17" frame would be great in the TT, but is more seattube than I want. Other decent frames with something like a 15" seattube and 22" or so toptubes, in the 6" or so travel range? Swap on most of my existing parts, resell the stock parts on my old frame is the plan. My current 66ATA up front, maybe a 8.5x2.5 rear shock to lower and slacken things a touch as well.
