I'm planning on switching from my 3x9 set up, and I'm wondering if you lot like the new world.
In particular curious about anyone on a 2x9; I'll lose a few gears obviously, but have been using a 12-27 cassette so won't miss the upper ones, I don't think.
Anyone know if middleburn does a 26t-39t combination duo in the front?
My bash ring gets far too much abuse for me to want to use a dedicated 2x set up.....
i recently bought a new charge duster with 2x10 gearing (my last bike had 3x9) to be honest am loving the new layout.i reckon that i use a lot more of the rear gears,than with previous bike.also you only loose the lowest/highest gear ratios so 99% of your 3x9 is still there (as you can use the whole cassette) am sticking to 2x10 from now on (also easier to clean chainset) 😀
I use 2x9. I've never used anything else, so there's no regrets. If I'm ever spinning out in top gear, I don't wish I had a third chain ring, I just wish I had a trail to ride instead of a road!!
22.36 on both my bikes.
I find that the gaps between gears is worse on a 36 than 32. this is particularly bad on hg61 12-36 cassette.
#EDIT: don't feel a lack of high gears though
I went 2 x 9 but regretted not going 1x9 sooner!
i'm using 2x9 for about 6 months now, no regrets at all. Maybe if i had to ride much on the road to get to trails with people that ran 3x9 i might be a little slow, but i don't. Benefits are, you run a tighter chain so it will drop less often and greater clearance. Will be going to 1x9 at some point soon.
What about low gears? ever miss the lowest ones in technical stuff? spend more time out of the saddle on uphills?
Pah...go 1x10 with a 36t cassette & man up y'girl. 🙂
why not just start fell running. . . 🙂
My lowest is 22-34. I can ride up walls in that gear!
What about low gears?
not missing any on my set up.
Running 26-39 at the front with a 12-36 at the back (stock set up on my Whyte 905).
Was a bit worried about the lack of low gears as I had been experimenting with steeper and steeper uphills, but any I cleared with a 22-24 I've also cleaned with a 26-36, and frankly it felt easier and more controlled. Maybe the geo/weight of the new bike helping, or just a considerable amount mroe road miles in between. Either way not missing low gears.
Not missing the high gears yet but have entered the Selkirk marathon this weekend and remember finishing it last time chasing someone down on a long flat section in my biggest gear, so hope I don't end up thrashing along in a 39-12 this time!
I regret bothering with it before I went to 1x9.

24/36 and 11-34 is spot on for me - never ran out of high gears offroad and the low gears are no different to before. I'd never go back to a triple unless I was going to be doing a lot of road linking sections and even then I'm not sure I'd bother.
Basically, 3 chainrings is for birds!!
new world? been agood few years now...
don't miss high on trail, just occasionally on road as mentioned.
don't miss low unless steep pinches at end of long ride; but i'd probably hurt or walk if I had a lower gear too, so no drama.
Overall, the only issue I have is when i spend a prolonged period off the bike, then it can be hard work up the climbs for a ride or two.
28,38x11-34, 9spd fwiw
27/40 on the front here with 11-34 on the back.
Very nice - never used the big ring at the front anyway and 27/34 on the back is very spinny - I would only want more on the type of slope where you would need to stand to manage your weight distribution anyway, which would then mean I wouldn't have used those gears anyway.
I still think 2x8 might be have been better as the 8 speed chains cope with mud better.
No they don't!
Just as 10 speed works just fine in mud.
None, best move I made on my bike.
Been using 2x9 on my bikes for a while now, just changed on one of them to 1x9 and wish I had earlier (34 front - 11-34 rear). Not so fast on fireroad descents but that doesnt really matter unless you are racing and I have a bike for that.
I've gone 27/40 - 11/32 and it's been great round the Surrey Hills. Was worried that I might struggle on the trip to Wales 2 weeks ago but it was perfectly fine
No they don't!
yes they do - they clear mud easier and they don't feel (as much) like you are grinding your drive train to hell.
yes they do
oh no they don't!! 😆
2x10 39/26 with 11-36 on my Scott Spark and never run out of gears for up or down. Rarely come out of the big ring either tbh
TurnerGuy - MemberNo they don't!

I'll leave it after this but having been through 7/8/9/10 speed and the claims at every jump that they wouldn't cope as well, this simply isn't the real world result.
oh no they don't!!
and your evidence for this is - how many winters riding on 8 speed do you have under your belt and how many years 9 speed?
It can't be much for clubber as he is only 21 - he has probably never ridden 8 speed...
this simply isn't the real world result
it simply is - the narrower chains hang on to the mud more and consequently grind the drive train more than eight speed used to.
Maybe you just don't go out if it is too muddy?

You didn't believe that did you 🙂
As I said, I've been through 7/8/9/10, used through the year and as it goes in proper muddy conditions. I've worn out several drivetrains. Never found that 8 lasted worse than 7 (obviously since they're basically the same), 9 worse than 8 or 10 worse than 9. I don't know anyone who's actually found different though I do know plenty of people who claim it despite sticking on 8 speed and never having actually tried 9 or 10...
good stuff all, going to go for it.
anyone know if middleburn does a 26 - 39 set-up for the front? the 27 - 40 looks to be their standard
well with 8 speed I never remember having to stop and empty my drink bottle out over the chain to make it ridable again, and the bridleways I would ride would be turned into deep mud pools by the local horses.
Plus the grinding feeling appears to be much worse.
Once I had changed to middleburn chainrings and an XT 8 speed cassette plus regular chain replacement I managed several years without changing the drivetrain, but that hasn't been the case with 9 speed.
I think 26-39 would be too close to 27-40 for middleburn to bother.
Why do people constantly overanalyse things on here, just try it FFS!
You are losing a chainring not a testicle 🙄
Chucked the big ring on all my bikes due to lack of use and too much grinding it against rocks/roll ins. 22/32 normally but on my xc bike 22/36 all with an 11-32 cassette. Only problem is the amount of time I spend in granny on my xc bike, (36x32 is just a bit tall for hills) so more front shifting and faster wear on chain/granny.
RE 26-39 setup I thought SRAM patented that well the 1.5:1 front ring ratio anyway.
I thought SRAM patented that well the 1.5:1 front ring ratio anyway.
how can they give a patent for that - jeez
That'll be a US patent if it really was patented. You can patent just about anything there even if it's evidently not new or even sensible to patent.
phew - I was worried about being spotted riding around in that ratio by some SRAM employee
Stupid question - will a normal triple front mech cope OK with a 13-14 tooth jump between two chainrings if used with 2x9, or would I need a double-specific one?

22/36 on the front with an 11-28 cassette.. which was great until I moved to a different area.. now I really wish that I had an 11-34 cassette..
Yes, it'll be fine. I had a triple mech doing 36-22. Only changed to a double-specific because I changed frame (different pull).
I run 22 / 36 chainrings with standard triple mechs with no issues
Apparently you might be able to lose some weight by running a road double front mech.
Shifting's not as good though IME - I used a Dura Ace 7800 one for a while.
I liked 2x9 (over the years I used 32/44, 30/42 and 28/40, all with 11-34) and 2x10 (28/42 and 30/42 with 11-36), but prefer 1x10 (36t, 11-36). Would probably still run a double on a less racey bike, but would never go back to a triple. IMO a 22t chainring is useless, you have so little momentum.

Depends on if you are old and fat and like climbing big hills - got any big hills where you are?

On two different bikes: one with a mid-cage and Gamut double guide, the other with a long cage. Sus and hardtail, both running 120mm+ forks.
In anywhere with decent hills the 22 will get used regularly.
