Yup happened to me too and I didn't realised for a while. You can see them because you are logged into google but we can't.

If you want to embed images from Google photos in a post so that other users can see them, the following works:

1. When viewing the image on the Google photos website, click the share icon at upper right, then click on "create link", and copy the link for sharing that Google presents you with to the clipboard.
2. Go to the website https://ctrlq.org/google/photos/ and paste the link from Google, then click on "Generate Code".
3. When the website has grabbed the photo and generated the code, it will show you two versions of the embed code you can use. I nearly always use the direct link version, as most message board websites are setup for you to use an image link that way.
4. Click on the "Insert image" icon in the toolbar here and paste the direct link code.

I just followed the four steps above for the image below, of a pair of wheels I built using LB RRU25C02 rims:

Nice wheels.... I would like to build the same rim but rim brake model. Did they set up nice with the tubeless.

do you know the PSI i would need in my LB wheels... I have the 45mm 18/25 width with 25mm scwalbee pro one tubeless, my weight is 175-180 lbs?
thanks

The SRAM TyreWiz app recommends 62/65psi. That’s assuming a 20lb bike and tyres measured at 28mm width. Image

The reply 62/65 is very good.. I go a mite lower on the front... somewhat softer. Usually 55-57 for me at low 180s.. no difference rolling.. even in my roll out tests.

Wow..

Between 55 /65.
Very low no?
Clincher tires are about 110/120 and we can put 50% less in tubeless, even at 175-180 lbs

I tried the tyrewiz app but we can't choose if the tires are tubeless or clincher....
So the psi they give us is for what?

55 w Pro Ones front rides very nice. Consider also..warm weather.. asphalt roads warm the tires and I'd guess an increase in psi over cool reading. At our 180ish wt we're moving around ~200 lbs.. say.. depending on your riding position per wt distribution front.. that rear tire is carrying ~120 to 130 lbs.. at 65 psi. The remaining wt front will compress the tire..giving a smaller 'road patch' at 55 psi.

Sure... higher psi's is a tad faster.. but below 20's mph nothing I can measure in the real world. Tubeless w my Ti frames.. set the psi for comfort... a setup easy on the rider. Long rides are very enjoyable.

Yes, I've been running them tubeless, and they were easy to setup - not with those Schwalbe tyres, but with Compass Bon Jon Pass 700x35 extralight, which I think are great tyres. At training ride pace they give very little away to 25s or 28s, but are much more comfortable over anything but perfect road surfaces. I've been running them at 40psi front and 55psi rear - I weigh about 66kg. I agree with just about everything in this road.cc review of them: https://road.cc/content/review/254350-c ... extralight.

This is the bike I've been running them on - an Open U.P.P.E.R.

Given road tubeless use is only a small % of the riding population, I will assume the TyreWiz App is for clincher tyres, and you can adjust 5-10psi lower for tubeless.

Ok I see, so this apps is really not reliable .
Go with mavic apps if you want something reliable.

If flat protection is not considered, tubed and tubeless with the same air volume and want the same optimal pressure for the same dampening effect and rolling resistant use the same pressure.

The reason people usually pump clincher higher than neccessery is to add more pinch flat protection.

I believe tyrewiz calculate only with performance (on wide rim) in mind, and don't really care about pinch flat. (mind you, pinching tubeless although may not result in flat, still can damage the rim). Therefore, it don't artificially inflate clincher higher than necessary.

Still, you can manually adjust it to your preference.
