Vaya 2 2x10 gearing
 
Recently purchased a 2012 Vaya 2 and find the 48/34 11-32 gearing a bit high for this old guy and the local hills.
Disc brakes add confidence for descents. Bike is 2x10 sram apex. Looking at options, I keep coming back to changing
crankset to Sram GX-1000 36/22. This would give me 19-89inch gearing without needing to change cassette and RD.
What concerns me is I don't see this combination used often and wonder why?

Edit: Apparently I rambled: The question is would switching to Sram Crankset GX-1000 36/22 be a good solution to
lower gearing. While keeping original 11-32 cassette and med cage derailleur.

When I set up my Rohloff bike for touring, I my highest gear is 85.1 gear inches. I often spin out on downhills. I wish I had higher, but I am unwilling to give up any of my low gears to obtain a higher gear. My point is that with a high gear of 89 inches, be prepared to spin out on shallow downhills.

Since you understand gearing calculations, you could try to figure out which gear you currently have that would approximate that 89 gear inch high gear, and then try riding some without ever going into a gear higher than that to see what that might be like.

I do not use those higher gears that often, but on shallow downhills or when I roll down into a valley and want to maintain momentum part way up the other side, I often appreciate having the higher gears to.

Thanks, I have compared current gearing and 48/15 or 87 inches is the tallest gear I can't live without.

umm, like, so what's the question?

The Shimano GRX 48/31 crankset would provide the gear range you are looking for. This eleven speed crank will work with a 10 speed SRAM drivetrain. The 36/22 is not a good match for a road drivetrain. A road front derailleur probably won’t work with the 36/22 mountain crankset.
