Hi, I am looking for some comfy, yet fast tubeless tyres. I previously have used 25 Schwalbe pro one at 70psi. My Venge pro disc can take up to 32mm. What would you recomend?

From Schwalbe you could have Pro One in 28mm and now in 30mm. There's also the G-One Speed in 30mm, a tyre I really like.

I have the G-One Allround 35 mm on my Domane, by far my longest lasting tire and first tubeless. I would look at the G-One Speed if I am to set up a more racy bike for sure.

I've ridden the G-One Speed as tubeless for 2000 km. I then went to 28mm Pro Ones, and the speed increase is very noticable. Not going back to the G-One Speeds. It's an easy 2 km/h gain.

We have G-One All-Around on our gravel bikes, so are the G-One speed more road oriented as opposed to gravel/multi-surface use?

Michael - The Anaerobic Threshold is neither...

The G-One Speeds are quite different from the G-Ones. Same compound I guess, but the knobs are much smaller and lower. They are supposedly very fast rolling.

I just looked at this. These are all decent - GP5000 TL is in 28 and 32c. Specialized Roubaix . Schwalbe Pro one (this fit a size up) and G-one Speed (G-one with smaller knobblies). The GP5000 look to roll just as easy as the smaller sizes. The G-One Speed is good for light non-roading, but will be a few watts slower the others because it has a puncture protection belt the normal g-ones don't have (the normal g-ones may actually roll faster despite the tread).

my opinion is g-one speeds are not super fast.. only ok. My estimates are they cost me 20watts

I've not found them to be super fast, but I don't have that much to compare to.

Try the SWorks Turbo 2bliss 28mm, I've been on them a lot last year and really rate them highly, they come out at 31mm on CLX32 rims.

Oh bummer. Anyone tried Specialized Roubaix Pro 32s? I'm shopping for a 95% road, 5% smooth hardpack tire.

I just took the G-one speed 30c tires out for a ride. I didn’t have my group or PM with me, but there doesn’t seem to be a speed compromise at 70psi against my 25cPro One Tubeless at 90. Certainly better on road than my 38c Geavelking SKs. Kinda worthless on anything but super hard pack off pavement (esp at 70psi). They were noticeable slow in pretty hard pack, small aggregate trail. There a good 95% road/ 5% shortcut tire and a really good travel bike tire.

G-One Speed is 30mm wide, you don't need to run it 70psi, try 50psi. Won't make you any slower, will be more comfortable, and will be more suitable for off-road.
