You may find you need to adjust your saddle height some going to the steeper STA. Fom my experience in a drastic move forward over the BB on a 62cm c-c frame, I've changed saddles and posts many times in getting used to it. Different saddles have different stack heights, from rails to the top of the saddle. Different posts allow for varying amounts of expsore. If anything my overall saddle height is slightly lower now as I've altered my pedal style some. Assuming you're using the same saddle and post, it wouldn't be more that a cm. difference, I'd guess. If such would make or break a frame from fitting you, as in no exposed post at all, you're looking at the wrong size frame to begin with. Otherwise it's no big deal on a frame where you have say a fistful of post. That your fist size, so it can vary from rider to rider !
Bottom line with any such change, there's always those unforeen consquences in doing so. There's also this about how a steeper STA alters saddle setback, and thus one's reach to the bars. https://groups.google.com/g/rbw-owners-bunch/c/lelFFs9VBCM/m/UBFEL7FTCAAJ On Wednesday, September 24, 2025 at 11:42:03 AM UTC-4 Davey Two Shoes wrote: > Hey Gang, > I can't get a grip on this.
