I have a gravel bike with a 46-30 crankset. I'm planning on a week long off road tour with way too many climbs. I ride 7000 miles a year, but on the road. I wouldn't call myself strong.

Please help me pick a new derailleur that will work for me. I have Shimano 11 speed brake/shifters, so it has to be one of these I think...

Thanks

Chain wrap capacity.
A 1X only has to wrap the difference between the smallest & largest cogs/
Add a ring and it also has to wrap that additional difference.
