- 2 x 10 or 1 x 11?
Need to upgrade worn out 2 x 9 SLX chain, cassette, chainrings etc and think a refresh totally would make more sense.
I cant decide on whether to go 1 x transmission. Will i be left wanting at anytime? I ride mainly Dartmoor/Wales. Thoughts welcome…
Looking at XT BTW.Posted 3 years agonickjbMember
Went through the same here when my 9 speed wore out. Went for 1x and don’t regret it. Small loss in range but made up for by the other benefits. Biggest benefit for me is the simplicity. A front shifter isn’t exactly complicated but changing to a single shifter is much less to think about. Hard to explain but out on the bike it feels right.Posted 3 years agowhitestoneMember
Obviously lots of threads on this but here’s my take.
You have a slightly reduced range of ratios on a 1x system compared to a 2x or 3x, with a 1×10 setup with extender it’s about 3 ratios, depending on the cassette an 11spd system might only be 2 ratios. You adjust where this range lies within the old range by choosing the appropriate size of chainring, wheel size makes a difference here as to what to consider.Posted 3 years agoStevet1Member
I made a similar choice last week and went with 2×10 even though I have 1×11 on another bike.Posted 3 years ago
I worked out the ranges I used and 1×11 would cover them if I went SRAM 10-42, Shimano 11-42 didn’t quite cover it but I could’ve lived with the difference.
However I had three concerns that stopped me going 1×11 –
– I’m not convinced that chainline isn’t a compromise on 1×11
– Although 1×11 is maybe 50-100g lighter overall than 2×10 it is 150g heavier right at the rear wheel axle. Sounds nit-picking but I like to keep as much weight centralised as I can, and the rear as light as possible (for a given strength). A lot of my local riding is messing about doing jumps and drops and I hate a heavy feeling rear wheel.
– I’ve never had problem setting up a front mech, and haven’t noticed any ‘simplicity’ benefits from 1x on my other bike – it just doesn’t bother me having 2 shifters…
And reason no.4 – 42 rear cassettes and tiny front chainrings just look gash 🙂
I applaud SRAM for giving people what they’ve asked for but it’s Emperors new clothes IMO.NeptuneMember
I just got a new Whyte with a 1×11 Sram CX set up and its really much different to a double or triple ring set up, so much easier, so much less gearing overlap. I’d say i think that the 30 front ring is a little small though, i’m thinking that a 32 or 34 would suit me with that 42 tooth dinner plate on the back.
For reference i’d ride somewhere like Afan/ Glyncorriwg in the middle ring of a triple.Posted 3 years ago
1×10 or 1×11
Problem with 2×10 is I found the jump between the two rings can be huge and makes shifting clunky and unreliable. Plus you can’t sit in one ring most of the time and just shift to the granny for steep climbs. I had a 26/39 and neither ring covered general riding, so constantly shifting up and down. Unlike a triple where I’d be mainly in the middle.
I had so many problems with chain drop and jamming, then tried a 2x guide and chain sucked and ripped the guide off!
Got fed up and went 1×10. Love it. Though really does depend on fitness and what gears you are likely to use the most.
Try a gear ratio calculator and compare different set ups. I worked out 2×10 going to 1×10 I would lose a couple of gears top and bottom and I could cope with that.
1×11 would be the same but with just one more (it goes to 11 you see! 😉 )Posted 3 years agoallan23Member
Oooo, bandwagon thread to jump on!
Looking at something myself. Currently running 32T + 11\36 cassette on a Banshee Spitfire, without going into long winded health stuff I’ve not ridden much this year and I’m finding I’m struggling with the lowest gear.
My old Hardtail is 2×9 with 26T granny and 36T on the cassette and that’s been easier to ride.
I’d considered going 2×10 on the Banshee but it’s just so much faf and starts to get expensive as it’s practically a complete drive train replacement as its nearly all 1×10 Zee.
Figured I could drop to a 30T NW, get a 42T sprocket for the back. did some of the dull calculations on gear ratios and that should get me to something closer to matching the lowest gears on both bikes.
I’d guess I’d probably have to swap out the Zee Mech for a medium cage, it’s the FR Zee but not sure if it would cope with a 42T sprocket. Cheaper than a complete new drive train and I do prefer the simplicity of 1x something.
I could just use the HT but I miss riding the Banshee and it’s likely to be a long recovery.Posted 3 years ago

Run 24/36 then? or 22/34? seems an odd reason to change.
SRAM X0 cranks and their crazy proprietary BCDs meant a lot of things weren’t an option unless I got a replacement spider and there were none in stock for months. I ended up getting an X0 DH crank with a standard single 104 BCD (and then eventually got the same spider for the old cranks and put that on the hard tail to get the same set up).
And I wanted to try 1x anyway. As I said, 2x was pissing me off in many ways. I don’t think it was all down to the size of the jump between the rings. I’ve always hated front shifters anyway.Posted 3 years ago

that’s not a problem with 2×10, that’s a problem with your choice of chainrings.
Came with the bike, and was a bit clueless at the time about 2×10. Besides the options for the crankset buying independently were limited at the time from most retailer even though SRAM do a wider range of ratios. Though still all of SRAM’s options were the same jump between the rings whatever the ratio.Posted 3 years ago
