- I managed to get an 11-36 cassette to work with a 10 speed 105 derailleur (32T max). All you have to do is to screw the B-screw limit some more and avoid cross chains. - I have seen on youtube people make an 11-40 cassette work with their mid/long cage derailleur. Sometimes it works with the b-screw limit adjustment, sometimes you have to add an extra rear derailleur hanger. In both cases, you might have to buy a new chain, but at least these options are the easiest and the cheapest.
Just use grx crankset and front mech instead of the road cranks on your bike. 46/30 11-34 is a decent range for climbing and you won’t have massive jumps in the gears and a really long chain.
I ride a Bacchetta Giro A20 touring recumbent and I enjoy hills seated in comfort. My gearing is somewhat different from stock I run 153 mm crank arms with 22-42 chain rings and a nine speed cassette 32-12 there is no back and forth on the front , it is an either or . 9 low gears for loaded touring and 9 gears for everything else and as I have 2.4 lengths of chain there is no cross chaining wear to concern me. Comfort and speed , what more could you ask for? BTW I took 3 cassettes apart to get the teeth I wanted.
It took me some time to put together all the numbers that you expressed. You did a great job of making this custom set-up. That is the point, to experiment and find what works best for each of us. Well done 👏
Hi! I participate in ultra cycling events and therefore needed a special solution for mountainous multi-day races. Absolute Black offers super-compact (oval) chain rings that are compatible with standard Shimano Cranks. They offer 48\32 and 46\30. For example, 46/30 and 11-34 could work well for you. The shifting performance of the oval rings is very good. Also, there's limited evidence that the oval chain rings improve fatigue resistance when going Uphill. I certainly like using them a lot! Maybe this helps you..
Indeed, 46/30 could work. I will take it into account for my gear ratio analysis. In parallel, I am investigating a 1x solution. Thank you for your advice.
That is a 6% cadence change for going from a 32 to 34. That is quite substantial. Weights of cassettes are tiny differences and are dwarfed by bodyweight changes. Practicing grinding and doing strength exercises would help. Also when pacing it is important to think about altitude adjusted ftp and how it effects your cycling ability.

Great information, thank you.
If you want to extend the capacity of your derailleur,just use a Toopre derailleur cassette extender
