FYI with the caveat that I really love the dfuse thing and also I’m thicc

but new nonsense

the post in clamped via an expanding wedge, which rests on a shelf inside the ST
when installed properly there is a lip of ~5mm of aluminum, as seen in this gorgeous photo:

now this is where the real magic happens! when riding, as the chairpole flexes to pedal stroke, the CF rubs on that lip of aluminum and makes a wonderful sound. unfortunately, i’m not worthy of this sound and i need it excised from my life immediately.

today i tried riding with the wedge flush with the top of the ST, squeaking went away completely, but even at proper torque i had some noticeable slippage (with seatpost slipping at a greater rate than wedge but both slipping).

ive been wrapping my brain around what to do. the squeaking has to stop. one idea was packing something in on the “shelf” to raise it and add some aluminum can shims?
