so,i think my granny is 26t,if I`m in absolute bottom gear,26 front/36 rear how would this compare to 32t front and 42t rear running 1x10? I know there`s probably a mathematical formula but I reckon one you can explain things far easier for me to understand I really fancy the idea of making things simpler but I`m worried about the possibility of running out of gears on the steep stuff specially as I`ve got a peaks trip coming up.

Bloody hell mate! you are a star! Just got a brand new oneup 42t in black with the 16t cog for £30 delivered off that link you gave me - brilliant bargain - last one too, being a tart I couldn't have lived with the green . I owe you a pint when we meet for the forum ride. Hills ere I come! where you got this from Zulu?

Great question and I was thinking the same - got the 42t one up but was considering going 1x10 with it too - if I had a 32 up front only would that be negating the effects of having a 42t expander? Confused of Roojelly.

Good ay it always worth keeping your eyes out on Ebay (thanks again, Adam) I don't know how the lad was selling em so cheap (he had a fair few too) but it was all kosher and the parts arrived brand new in the wrapper.

Have a look here gears.mtbcrosscountry.com/#26I2I523 should give you an idea. I've order one from the eBay chap and wondered exactly the same thing. According to the above website if I'm in 32 front- 42 rear is should be the same as being in 24 front - 30/34 at the rear. I'd wondered the same thing,I never use the granny unless I'm in the Lakes and then only when I tired so hopefully the 32/42 will work out perfect.

if ive got it right on the link,my 26t granny and 12-36 cassette gives me a ratio of 2.17/0.72 32t chain ring and 12-42 gives a ratio 2.67/0.76 so..does that mean the 32/42 is slightly higher or lower?
#fuckedifiknow
ah,a 30t up front = 2.50/0.71,maybe that`s what I need to keep it as near as it is now.

I'm shit at this too - I've got the XT 2x10 38/24 on a 11/36 cassette. if I go 1x10 32 up front with a 42t expander won't I be swapping like for like and feel no real benefit? better to stay 2x10 maybe with the 42t for the peaks etc?

You're all pu**ies!
Pedal more, simple!
Having an 'emergency gear' is all well and good but I'll bet most who have one use it more than they admit!

Too much yamyam in this thread ... Stick to 2x10... 26/38 chainrings 11-36 at back.. All you really really ever need...
Or for #enduro look 32front 11-40back ..again all you ever need, i'm not the most fit but did w2+skyline shared climb in this setup but you spin out in the flats and say sayonara to your riding buddies.

Being 'enduro' has nowt to do with it tbf. I hated 2x10 because I was used to my DH bike. Never knew which gear to be in when I had 2x10!!! 30T front and 11-36T at the back is pretty much the same as 32T front and 11-40 back. I wouldnt waste money buying a 40T when I could just use a normal cassette

My 1 x 10 (36- 11-36) is spot on for me! May drop the front to a 34 if I go to the Peaks again! I really don't like these 'cop out cogs' lol

Not sure if you've worked this out yet but my understanding is : 26 front & 36 rear = 19.2inch travelled for one revolution of crank 32 front & 42 rear = 20.3inch travelled for one revolution of crank Therefor 26/36 is slightly easier (not much) than 32/42 (i think)

Here is my setup for 1x10 and 2x10 respectively. (Factoring crank arms and wheel size)
