All,

I am slowly coming to the realization that my 58cm Toyo Atlantis might be a smidgen too large for me. So I am considering buying one of the run of Sams that are coming this fall if they have canti posts. My hope would be to largely swap over all of my Atlantis build to the Sam (and selling the Atlantis frameset here). One question I have is about tire clearance. Riv says that the 700c 55cm Sam fits 47mm tires, but I would like to squeeze in my 50mm Gravel Kings. Has anyone had success with getting slightly larger tires onto their Sam?

Thanks,

Andrew

I run 43mm Gravelkings on my 55 canti sam w/fenders and they fit fine. I think the 50mm would probably squeeze in (assuming they are a slick tire, and not knobby), but you'd be leaving very little room for any debris. That might be an issue if your wheel is ever slightly out of true or dish. And I probably wouldn't ride off road with them.

There hasn't been word about whether the new run of Sams will be identical to the last. The current trend seems to be more and more clearance in each model year, so you may be in luck.

I am secretly hoping that the next Sam would be made for wider tires (and ever so slightly longer chain-stay).  There's no space in the garage for another bike, but I'll somehow make space in the living room if there is going to be a 51cm Sam that can run 650bx2.15 Almotions :)

Nathan, thanks. I've seen people running 50mm fenders elsewhere and that gave me some hope. Like you, I'll be interested to see if this new iteration clears bigger tires. I also hope its canti-compatible. 

Ash, somehow there's always more room in the garage........

The new Sams will have canti posts, and will come in "rbw blue" and "dark gold" according to Golden Pliers' most recent IG story. You could probably shoot them an email asking about the exact frame spec!
