If you stay on your 50 ring, the lowest gear ratio you can turn is 50/28 = 1.785

Assuming you have a 23, 34/23 = 1.48, if you use the small ring. And go even lower, although you shouldn't have to go all the way to 34/28.

My lowest gear in the back is a 25. At 50/25, that's 2.0. I get the same ratio on my 34/17, and I have a 19, a 21, a 23 and a 25 left to use if I need them.

Can I get up a 5% grade at 50/25? Most likely I can, but I get up them a lot easier using 34/21, for example.

Don't insist on staying in the big ring.
