Is 650b the right wheel size for me? 

I have the Grx 650 wheels. Good choice!

Another great 650b tire is Specialized Pathfinder. I’ve been running these for the past 2 summers , with a tubeless setup with great results

Good video, and explanations. Good luck w the 650b!

I run a 2021 Diverge Carbon with 700x48 no problem. Check out the Rene Herse Oracle Ridge's, those big 48's are great. I'm not a light rider at 195. But add in the weight of the bike plus a few pounds and I'm running 27psi (front) and 29psi (rear). No problems.

Perfect timing with the UCI gravel getting announced. Finally got new wheels back in stock 😂

Familiar roads! Sorry we couldn’t link up. Hopefully soon.

I have a set of both. 650b for Keystone Gravel and 700c for unPAved. Gravel King SK (stone kickers) are pingy too

been riding a Slate with 650bs for 5-6 years and found that, WITH MODERN TIRES, bigger is better... only miss the 29er's on MTBtype rides

Are you riding tubeless? I'm 6'-0", around 210lbs when i was riding Teravail Cannonballs in the 650bx47 size, tubeless on alloy rims and a steel framed gravel bike (carbon fork). A similar tire to the Venture. I think I was riding 26/28 psi. Perhaps your psi is too high, which leads to the pinging of gravel. I see 35psi mentioned on the WTB web site... but try lower pressure, experiment. My riding consists mostly of paved, packed dirt and soft dirt. I'm now riding 650bx2.1 around 20/24 psi.

Conti Speedking Racesport 2.2 would kill it across those kind of surfaces.
