equivalent gears

Hi

I was thinking about running 1x10 as I currently have 2x10

my lowest gear is 36 rear 26 front

I was wondering what gear I could put my bike in to test 36 rear 32 front on a 1x10
i.e 26 front 3rd smallest rear ect

Is a simple ratio. 32/36 = 0.889

Need to find a ratio that matches that.

Ohhh, I never really understood all the ratio stuff but there are some ratio websites about

I understand ratios, just not how it works in the mtb world

You don't need wheel size in this, as they are the same. You have a 26 front cog. 26/0.889 = 29.24. So you need to find the rear cog close to that.

Or do the same for your other front cog, whatever that is.

ahh I understand, just basic maths, I just never really understood how it applied to bike. thanks, I get it now

my rear cassette is 36,32,28,25

front 26 - 39

so to 'test' easiest gear with a 32T front ring I need to find a ratio close to 0.889

39/0.889 = is about 43 so that wont work

so it would be like 26 front 28 rear and it would be slightly easier to pedal with the 32 front 36 rear

Yeahh? I think that's understandable

I don't understand you at all.

If you want the same ratio as 32 front, 36 rear (0.889), but using a 26t chainring, you'll need
26t front, 29.25t rear.
But 29.25 tooth sprockets don't exist. So, the closest you have to it.

Yea so the closest I can get is 28 and it will be slightly easier going than that in reality

97th choice

Well, your 28 and 32 are either side of it. (I've done no maths to confirm this)
