My new seatpost is 1 cm too short -- high stack-height saddles? Thin shoes?

OK for the frame to have any less insertion?

No. Please don’t do it. It’ll be fine for a while, and then end in tears. It’s a matter of when not if.

More serious suggestion than bling pedals is could you let them the seatpost? If you can get a piece of an old alloy post the same internal and external diameter then put put a well fitting aluminium tube inside through the join, I guess about 70 mm inside each piece, and then epoxy in place. Yes it'll add some weight but would probably do the trick.

Have you ordered a high stack Selle SMP saddle yet?

Afraid not, although I do appreciate the suggestion. Their asthetic is a step too far for me (I for some reason kind of like the look of the Thudbuster though)

I did wonder this. I thought someone may make some sort of compression plug like thing for exactly this purpose, but my post seems to have an internal lip at the end that would prevent this anyway.

No. Please don’t do it. It’ll be fine for a while, and then end in tears. It’s a matter of when not if. 

Point taken. For now, I have gone back and measured very carefully -- turns out I can overextend the post 5mm and still have 5mm below the bottom tt-st weld. That, in combination with moving the seat back 5mm, has got my seat feeling close enough to the right position that I think I will stick with it.

I may still look out for a saddle with 5mm or so more stack, but the only things I've seen so far are trekking and urban things, which will likely compress so much that I'll end up in the same place as with my current seat.

The one I've seem that may work (SQ Labs M-D or something) is nearly as expensive as buying another post like the USE Vybe.

I reckon the best advice on here is to admit defeat, sell it and buy a longer saddle. It’ll be cheaper than a new frame when you inevitably break it

The older thudbusters had more normal clamps and seem to be longer - see bikeinn

Yea, it's annoying

It seems like the only (aluminium) suspension post Cane Creek now make short is the Thudbuster ST in 27.2mm

The Thudbuster ST in larger diameters is longer, as it the eeSilk+ and Thudbuster LT in all diameters...

Radical, but just set at the max insert and forget about the 1 cm lower saddle. After a ride or two you won’t notice. My TT saddle position is 2cm lower than my road position. And since it’s a single speed for off road, you aren’t sat on the saddle for that long anyway.

Well, in the end, I had to admit defeat, and order a Use Vybe, which is 50mm longer

The Cane Creek can go on my road/gravelbike on the occasions that I'm doing long bumpy rides
