I ride a normal 26" bike which i currently have as a standard shimano 3x9 but i've always hated front mechs and my rear mech is well worn, so thought i might take the plunge into the world of 1x10?
So priced up all the parts and wondered what the best size narrow wide chainring is to buy? my rear cassette will be 11/36 so thought around a 32 or 34?
Also could I kkep my granny ring on just in case i want to manually drop the chain on real steep stuff? just worried about not having enough gears.
Sorry if this has been asked time and time again
totally depends on how fit you are, how strong you are at climbing & what terrain.
As you are changing the rear mech & cassette you might as well go XT 1x11.
There is a choice of two cassettes (I think).
As for the chain ring, you want a narrow wide one, somewhere from 30 to 34 I reckon, depending on you, but they are not too expensive. Thinki about how much you use the granny now & then decide.
Cheers, looking at the 1x11 set up it's about £70 more so might go down that route instead.
Have a look at Sheldon Browns gear calculator and see what you're running in double granny then work out what you need to replicate it .
I did the same couple of months ago. I run a 34 raceface NW with an 11-36. I ride steep stuff in the peaks and some tarmac to link stuff up from home and it has been fine. I never ever used my granny ring anyways, I don't know why it took me so long. It is so much better and quieter.
If you use the granny, go for 30 or 32, if not 34 will be fine. You can always change though. Lots of chainrings in the classifieds if you need to swap.
I had my 901 set up perfect 1x10 32 Front with a 42T expander on the rear and never missed my granny. In the process of setting my new bike up the same.
You're lucky… jump straight to 11spd.
Don't think twice.
24 granny, 36 rear = 0.66667
32 ring, 42 cassette = 0.76
not that big a difference, absolute bottom gear is very spinny so there aren't that many places where you need it for an extended amount of time. my next bike will have 1x11 on it
If you can wait a few weeks the end of year sales will starting .

Yep. Around here even if you are reasonably fit it'll be a 30T front and 40T rear 🙂
I like my 1x10 but these days 1x11 just makes more sense imo. And as wide a range as you can find.
I've been using gear-calculator.com to compare gearing setups.
This link shows your typical Shimano 3x9 (22/32/44 triple chainrings, 11-34 cassette) compared to the XT 11-speed 32 x 11-42.
You'll loose the lowest granny gear and the top two on the big ring. If the lack of the granny sounds terrible drop down to a 30t chainring. The SRAM 11-speed kit of course has a slightly better range as it has the 10t cog.
That ^ sounds ideal, hardly use very lowest granny gear, or biggest 2 on big ring. Guess what my next upgrade is going to be...........
I went from a 3x9 Shimano setup to SRAM 1x11, (almost) never regretted :D.
My shifters were SLX, the last model without the crap instant release and heavy action lever; I found SRAM's shifter to be pretty much the same as the old SLX, so if you like that feel you might as well go with SRAM.
Don't you have to change the freehub to take an SRAM cassette though? The Shimano one should fit right on my current XT hub.
Always been a Shimano man i'm afraid.
To continue on that point...can you use a Shimano 11 speed cassette in conjunction with the rest of set up being SRAM?
I reckon so, it works the other way round- but most folks doing a hybrid will go the other way
Yeah for the SRAM 10t cassettes you'll need either a new freehub, or a XD driver thingy if you have a hub that can be adapted (like a Hope one), but that's something else to buy.
I've just made the move to 1x11 from 3x9
Well, I've installed it.
Badly.
Once the LBS get it working on Wednesday, I'll report back.
😳
What couldn't you get working? I would've thought it's easier to set up that a ??x2 or 3?
I'm in the same boat as OP. Like the sound of XT 11 speed if I can get away without a new free hub. Currently got SLX shifters/mechs but with BB30 and FSA cranks. Can I keep the cranks (provided I can get a NW chainring with the same BCD) and just buy 11 speed rear mech, cassette, chain & shifter?
I went from 3 x 9 to 1 x11 on Zesty - great change no regrets
zilog6128, yes, though I believe you'll likely need new (shorter) bolts to put the single ring on.
The statements of 'it' is fine' cold do with some more info about where you ride. I do find myself spinning away in granny (possibly just a Jessie), but equally the last couple of weeks I have been without granny ring - and managed just fine.
So anyone else manage 1x11 in big hills / Scotland / Lakes riding, not just Glentress...?

Got 1x10 (30Tx40T) in the Borders on my FS but tbh it just doesn't have the range at the top.
Which is mainly why my HT is still on 3x9, hard to look at anything different for a miles bike, as everything else is really a compromise (obviously except for 3x10, which is pointless as I'd be replacing like-for-like).
speaking to CRC it looks like the 11 speed cassette won't go onto my XT rear hub, so a new wheel would be needed.
Looks like it'll be 1 or 2x10 then
pickle: or x11 from Shimano. It's only SRAM 1x11 with the 10t small cog that doesn't fit on a standard MTB freehub.
That's not what CRC told me, they said my XT hub wouldn't take 11 speed XT. My hub is about 3 years old standard old fashioned QR hub.
I thought 11 speed would fit but i'm really confused now 🙁
Thanks!zilog6128, yes, though I believe you'll likely need new (shorter) bolts to put the single ring on.
Anyone know if there's a reason why I couldn't use SRAM crank/chainring/chain with Shimano mech/shifter/cassette? (cos that's what I'd like to do!)
pickle: they're wrong. The Shimano cassettes fit on standard freehubs.
zilog6128: no reason at all, the chains are the same size, a chainring is a chainring, and the crank itself is obviously unrelated.
Will a 9spd deore triple crank be OK on 1x11 with new single ring in old middle ring position?
Probably CRC got confused between Shimano road 11 speed, which doesn't fit on a normal freehub, and Shimano mountain 11 which does.
thanks rossburton
moab - I run 1x9 30-34 in the lakes which means I'm missing a bit at the spinny end and do miss them a bit on the really scrabbly steeps but only the stuff that's 50/50 whether you'd be better pushing anyway. It's a bit like s/s - if you're anticipating it you but a bit more effort into carrying momentum
core: my wife's 1x9 botch job that I build has exactly that, so yes. A dedicated single-ring crank is just lighter and neater.
Cheers guys, it was strange though as their response had links to the XT 10 speed stuff.
