It’ll fit in a D-shaped seat tube?

Brilliant wwaswas 😀

Seriously though, very easy to line the saddle up. I’ve got a couple of even odder shape ones, Yeti ASR-C and Scott Plasma, no problems at all. Both apparently done for aerodynamic reasons. It may help in a time trial on the Plasma at 25mph+ average, whether it makes much of a difference on the Yeti at 10mph average I don’t know, I suspect not.
Yeti one needs a special adapter to fit a work stand though.

I must be having a slow day today, as I never even considered that.

Cool! Can we have d shaped steerer tubes as well please so I get the stem on straight every time?

I’d rather have my saddle twist than puncture my arse!

Likewise with a stem.

Actually thinking about it, that would be brilliant. You could do without the clamping bolts on the stem and just have the sfn and pretension bolt.

I am officially a genius.

It is to allow forwards/backwards flex for ride comfort while maintaining sideways rigidity under pedalling. The flat edge on the rear will be much less resistant to flexing than the rounded edges and should therefore allow the post to bend backwards to some degree when you hit a bump.

Less torque required to clamp it? I find seatposts rarely slip down, but often spin round.

Is the point that once you’ve got a D-shaped frame, you have to buy their D-shaped seatposts?

Oh, also, once a seatpost’s stuck in, not being able to twist it to help get it out will be a super-mega-bollocks.

Makes sense. Not much info/specs about to verify yet.

From some road or time trial bike with a ‘D’ shaped section seat tube so that the tyre can be closer to the aero profile of the tube?

CX bikes, HH. So might help with mud clearance?

I just assumed it was an ISP. Although now I look at the pic that’s the bottom, not the top 😳
As if there weren’t enough seat post sizes out there we now have yet another standard. Bollox
