So today I was able to buy a Sram 40t x-sync chainring for $35 locally. Obviously it fits no problems with 0mm offset. Bummed I can't use my other larger chainrings that integrate a power meter though. But I will be wearing road shoes most of the time, so my set of Magene PM pedals will be just fine.

Using a 10-46 XPLR 13 speed cassette. No where will I ever need that 40x46 gear. Thankfully that 40x10 gear is equal to Shimano 52x13 which is good for 32-33mph at like 100 RPM. Both extreme ends of the gear range are such extremely small use cases.

That said, I think I will eventually swap in a regular Sram Force road derailleur and use a standard 10-30t or 10-33t cassette. This way I will have far more usable gears with the 40t crank up front.

Also my Specialized Pathfinder 45s stretch to 47.5mm at the rim. Ascent Big Chungus wheels   
Plenty of clearance.

It's a bit long recovery, but now I can "walk" a little, it is on a good way!

It really depends on the kind of terrain you plan to ride, but for sure a 40x46 gear you'll be climbing trees! I think you might be a little limited on flat roads if speed is your main priority.

Using a 10-51 XTR cassette, with 42T chainring, it was a versatile setup. However I would have liked a bigger chainring for flat road and smoother gravel sections.

Either way, you're going to love riding this bike!
Can't wait to see your final build

The final step to complete my Graro gravel build is also the only pain point: Chainring compatibility. I'm running Sram E1 XPLR 13p.

I'm stupid and didn't read the website. My Sram aero/road 50t 1x chainring doesn't clear the chainstay. So I bought a Wolf Tooth 46t chainring thinking that would solve the issue. It did not. So now I just wasted $100 

I read through this thread yet I'm still confused. Is it actually possible run a 46t chainring? Ican says 42t max for 1x but some folks still had issues with clearance?
What if I just buy a Sram XPLR/DUB-Wide crank arm set. Would that be enough to clear the 46t chainring with the proper spacers? Sram says 2.5mm on the non-drive side, and 5.5mm on the drive side.

Thanks in advanced

Hi,

I rode the Graro for quite some time until a car hit me while descending a hill, sendinf me to the emergency room a few months ago. Anyway.

Initially, I was able to fit a 46T chainring with a 0mm offset, but I had to use a spacer to prevent it from rubbing against the chainstay. The chainline wasn't ideal, and the clearance was very tight. There was probably 2-3mm between the chainring and the frame. So I switched to a 42T chainring for a peace of mind.

Also, Ican said that the max tyre clearance is 45mm, but you can actually fit 50mm without any issues. I measured my tyres at an actual 52mm. However, I wouldn't recommend going any wider
