Yes, I'm finding that and 25mm tyres are on the cards. Cheers

You can use all the calculations you like but in the final analysis I use my arse.
Is it comfortable or have I got too much pressure in those tyres
Thats right, I'm about 70kg and run on 700c x 25, I'm running 70psi back and 65psi front, I find much higher and I'm getting my fillings rattled

Riding on 23c tyres on our road surfaces . . . really ? 28c minimum for me nowadays.

I'm on a gravel bike riding on Schwalbe G-One All Round 700x35c pretty much bomb proof on any road surface. I would not jeopardise my comfort and safety for the minimal increase in speed I might get with a 700x23/25c tyre !

I agree, but one of my bikes tops out at 25...Riding on 23c tyres on our road surfaces . . . really ? 28c minimum for me nowadays.
28 on the other. With a wider wheelset, room for more, but happy with 28 for now.

I have 700x28c on my road bike (max accepted) The increased comfort when riding the gravelbike (700x35c) is immediately welcome.

I *might* get 32s on the mixte with the current Shimano rs550 wheels, but they spec 28 max. Currently have rigid Luganos on, so folding 32s wouldn't add much weight, not that it matters that much anyhow! When these have had it, I just might try it.I have 700x28c on my road bike (max accepted) The increased comfort when riding the gravelbike (700x35c) is immediately welcome.

700c x 25 is about as wide as my bike takes.

@sebinho if you've not got one already - a track pump can help with accuracy and ease. I've got a bike that can only take 23c front (can just squeeze a 25c in the back) I'd go with others 5-10 less in the front, some tyres focus more on comfort than speed & others puncture resistance. Good shorts / saddle , bar tape and shoes can also make a difference
Thanks, yes, I have this type of pump. My frame apparently can accept 28mm tyres, which would be nice. The forks however I'm not sure about as they aren't the originals. I believe they are ITM Pyro forks - have written to ITM to ask about maximum spacer height (below the stem) and will ask about max. tyre width too). I hadn't thought about mixing tyre widths. Perhaps 25 on the front, if limited to that, and 28 on the back might give better comfort. I'm not really the lycra type (nothing against!) but I am considering the shorts!

Looks like your front can go 25c (I tried squeezing a 25c on my front - it would fit just, but any road sludge / 'dust' clogged up to quickly...). My new bike can go to 30c but came with 25c and now the tyres are wearing and before moving to winter I'm.going to go to 30c (you can get normal looking 
shorts with padding inserts as well)

Being 'Gravitationally Challenged'* I found trying the maximum allowed in the back and about 90-95% of that at the front worked for me.

Thanks for your help @craigwend ! I'll write to Ribble about the spacers.

I’m on 26’s and find 90ish on the front and 95-100 psi on the back is most comfy and touch wood …..
Forgot to mention I’m around 75kg …
