Schwalbe Pro One Tubeless Measurements?

[YesNdeed]

Anyone running the 28 size, care to grab some actual numbers? I'm thinking about grabbing some, but the clearance @ front brake caliper is super tight with IRC Roadlite 25s which run huge. Rims are Pacenti SL23 V2. Much thanks.

Depending on how huge the IRC runs I'd stay away from the 28c Pro One. I ran 25cs on narrow Fulcrum rims and they measured 26.5, so I would imagine the 28 on a wide rim could be bigger than the IRC.

I'm thinking that's pretty accurate, but had to check. Twin pack 28s at PBK are dirt cheap! IRC 25s run 28/width. Roughly 26 or so from rim/tire to tire center.

Guess I'll be waiting for a pack of 25s. Thanks for the measurements!
