To me this seems like quite a good idea. If you own a bike that is currently running 29er wheels and tyres then you can drop a set of these in to run road or gravel tyres.
But you can do that already in a size with far bigger manufacturer support.
Remember when they tried to convince us we needed 29er specific saddles. Good times.
Do you mean 650b and 700c which is what I currently use? Of course and it works well. But I quite fancy a salsa cutthroat and that would need 750d to work. It’s a niche but cycling is full of those. 29x3 and 26x4 need far more adaptation of frame, fork and even in some cases bottom bracket than 750d

Can't be real, ... oh! https://www.bikeradar.com/news/fizik-debuts-29er-specific-saddle/

"work" doing a lot of heavy lifting there. I guess if you want the BB to be in the right place then yes, it'll do the job
The equivalent rolling diameter to the 2.25" tyre that your Cutthroat is build around (736mm FYI) for 750D is 38mm/1.50 (assuming the manufacturer isn't lying). The same sized tyre on a 700C rim would have a rolling diameter of 698mm resulting in a total BB drop of 19mm. That's not actually bike breakingly bad for a gravel ride but I guess could catch you out with pedal strikes.
I guess for road it could work but why not stick something like a Maxxis Grifter on and just enjoy the ride?
Look, it's all subjective and I'm not going to get annoyed because someone thinks a niche product suits them, more power to you. It's nice to have options but I guess we agree that's all it really is.
I’m not exactly wedded to the idea of 750d.
I have had a few rides on my bike with 650b where I had a night mare with ruts. So bottom bracket might does matter some times
Can anyone tell me what the b, (650) c, (700) and d in 750 signify please?
It's the notional diameter of a standard width tyre. So 700 a,b and c all have different rim diameters but work out to 700 somethings. It's French so probably makes as much sense as gradians (to someone unfamiliar).
I think.

ISO sizing makes much more sense as bead size + 2x tyre width = diameter.
Cheers squirrelking, got it now using Sheldon's page. He's nearly as useful as this place. 😁
