650b on the new Ritchey Swiss Cross Disc, V2?
I love the Ritchey Swiss Cross Disc, and the 2020 model has clearance for 40c tires, which is awesome. However, I'm also interested in running even larger tires using a 650b setup. Searching high and low I can't find a single photo, or even a discussion, of fitting a 650b x 47c or bigger tire to a ritchey swiss cross disc. I'm a bit concerned its impossible.
Anyone have experience with this? Even better, a photo of a 650b setup on a Ritchey Swiss Cross Disc?

Guess not...
I love the bike, and it would look quite interesting with skinny tubes and fatter tires.
Its going to depend on the clearance - mostly the width of the stays and forks. If the tubing flares normally, I would think it could work. I'm thinking that bike was designed for 33mm cross tires, so it should work just fine geometry wise with 650bx47mm tires - that is practically the same geometry. I can't think of a reason why it wouldn't work - as long as there is appropriate flare in the fork/stays.
Just make sure what you buy has a good return policy. ;-)

I never tried personally, but I did find this wonderful photoshoot of a Ritchey Outback V1 setup 650b with 48c tires. I tried to link it below but apparently I don't have enough bikeforums privilege. If you google woods cyclery ritchey outback 650b you will probably find it. There's also some more stuff if you search the #ritcheyoutback hashtag on instagram.

I recently purchased a 2020 Swiss Cross Frameset and have a set of 650b wheels laying about at a different location. Given the 40c clearance, it is possible but looking at the rear stays alone I'm not optimistic. I'll collect the wheels later this week and have a clear answer on 650b fitment.

The Red/White fade was a limited edition to celebrate the model's 25th anniversary. They are likely sold out by now. I have the black. Ritchey just introduced a white frame with red decals.

Clearance on the 2020 Swiss Cross is too tight on the chainstays for anything wider than a 650bx40.

Chainstay clearance with a 650bx38 tire

Stay crimping ends near the widest point of the tire

The widest point of the 650bx38 falls exactly in the middle of the width of the yellow tape

Seat stay clearance is ample
