28c is the smallest I've gone tubeless. ...and I just built those wheels and stuck Schwalbe Ones on em. Haven't even ridden em yet.
The other wheels have 32c GP5Ks on em. No problems in the 18mos they've been on the bike M |

That means nothing if not compared to other gauges of known accuracy. A digital gauge can be inaccurate. Pressure that's too low may work fine under good conditions, but there's a point when too low increases rolling resistance.

Dave, I've been running 700x32 GP5000TLs on Belgium + and they measure out to 33.5 mm at 55-60 psi so it's close to 35mm. This week I threw on 28mm GP5000TLs and I'm at 29.6mm width. It's subjective, but I really like how these roll for my 145 lbs. You might consider 28-30mm for your next tire and skipping 32 as that might be close to your 35 tires.

Dave, wrt pressures on 25mm tires -I was pretty surprised, too.
These numbers are based on a glycerin filled Winters gauge that I added to my pump w/ an extension to place it at the handle instead of my feet. So much nicer than the chinese gauge with teeny tiny markings, stupid range, etc. I was curious about the liquid inside the dial and the guy at the hose/fitting shop told me it was just to stabilized the needle on machinery that vibrates. Love learning new things. |

Thank you all for your opinions and true-life tales! I find these back-and-forth dialogues here truly helpful. This is like Rotten Tomatoes for tubeless tires.
And when reported data matches up, very cool. I’m also 145 lbs and will run the same 700x32 GP5000TLs whenever the supply chain delays produce my backorder. Until then, I’ll ride this incoming bike with same size GK slicks. I’ll mount either 700x32 tire on Velocity A23s, curious what real measurements will be at around 55 psi. Thinner tubeless tires will be a winter project for one of my more traditional road bikes; see about 28s and 25s. See what the world’s supply chains make available in our very internationally sourced sport. Dave, who likes to figure out for any bike how many different nations contributed to the build and memory says 9 has been the highest number Quote:

Sounds like a great kludge. I’m trying to picture your setup. Might you have a photo or two you could spare?

...I suck at computers
I'm embarrassed to say that I don't know how to add a picture but I will try to figure it out. Maybe add a bike pic in a thread or two! |
