34 front/36 rear is the same as 24 front/? Rear
Also 34/34 to 24/?
34:34 is 1:1 so 24:24 🙂
Sheldon has a calculator for the rest

don't worry about the rest of the info about wheels sizes etc; - you're just lookign for ratios that give the same gear inches.
[edit] if you need to use a 24 front chainring to get up the hills then a single ring up front is probably not for you, tbh.
34 front and 36 rear is roughly equivalent to 24 front and 26 rear give or take a couple of %.
As wwaswas says 34 34 is 1:1 ratio...
ratio-wise:
25(.4)
24
You're better off using a gear calculator. For example 26/36 is NOT the same gear inches as 22/32... there's about an inch difference.

frontrear 32 34 36
22 18.1 17.0 16.1
24 19.7 18.6 17.5
26 21.4 20.1 19.0
I was puzzled as I thought it was about ratios, but it's also about the different leverage at the chainwheel
Sorry, above table is for 700c, here it is with 26 x2.25
F/R 32 34 36
22 21.0 19.7 18.6
24 22.9 21.5 20.3
26 24.8 23.3 22.0
or example 26/36 is NOT the same gear inches as 22/32... there's about an inch difference.
Different ratios anyway, though, right?
It isn't teeth difference, it's teeth ratio, so front teeth divided by back teeth.
e.g.
22:11 = 32:16 = 44:22 = 2
24:16 = 33:22 = 42:28 = 1.5
22:22 = 32:32 = 36:36 = 1
That's what I meant, I just didn't explain it very well.... I used to think that the difference of 10 teeth front to back would give the same result.
