2x and 1x the truth pleae !

cakefacesmallblockFull Member
OK. For a while now I’ve considered 1×9 on my Trance, I’ve fitted an 11-34 cassette and been riding lately just using the middle ( 32) ring on my current triple chain rings.
I’ve decided that running 1×9, just maybe a stretch too far for my ageing legs on some of the steeper stuff I regularly encounter, ok so, just maybe go 11-36 in due course.But meantime…I can see why I may need a chain device if I go 1x, but am confused as to why one becomes important if going 2x and can’t see why a bash alone, along with the front mech doesn’t alter from big outer ring and mech.
I apologise for maybe going over old ground, but can’t find a reasonable definitive answer, if there is one !
So, SLX Shadow rear mech ( not shadow +), front mech and bash, will not having a chain device make it any more likely I’ll drop my chain than as it is now.
Yours, slightly confused ( or thick) .
tmb467Free MemberI did that and my chain kept coming off on rocky ground, so much so that I’d get confused, think I was in the wrong gear and try and shift the chain back on again even tho the mech couldn’t move cos I’d limited the travel
Eventually I snapped the shifter arm off (only took a few rides to do it too)
Not sure why it was happening cos like you I reckoned if it didn’t jump with a triple then why would it jump with a double and bash. Think it must be the ramps on the big ring that stop it – but anyway, yes it does jump and in my experience it can be a right ball-ache.
I’ve ended up going 1×10 with an 11-36 cassette (but it was something I wanted to do anyway). Saved about 600g on my previous set-up too, so I’m happy
650briFree MemberI was running 2×10 with no chain device and its a pain. Fitted a blackspire twinty guide now and its so much better. without it the chain bounced off.
must say though, the old triple did me proud without at issue for bloody years. progress eh.kayak23Full MemberI think a 32t ring up front and 11-36 will do you fine depending of course on where you do most of your riding. I think that 1×9/10 makes you ride slightly differently anyway, and perhaps you attack the hills a bit more.
I certainly find it hard to ride behind folks who drop into their grannies at the slightest incline as they tend to climb a lot slower than I have to.As for chain device, give it a go without, you’ll soon know if you need one or not. I personally use a full chain device on my 1×9 full susser and have just switched back to 2×9 with a Blackspire Stinger on my hardtail. I find the chain keeps jumping off the front and it’s driving me nuts.
Can’t wait to go back to 1×9 with a full chain guide(After a particularly hilly trip I’m doing)cakefacesmallblockFull MemberThanks guys.
To be entirely honest, I am starting to think that unless I just go the whole hog and 11-36 out back and 1x , that I’m starting to hype myself into fixing something which, frankly, ain’t broke ! 😕scotroutesFull MemberI run 2×9 on my fatbike with no chain device. Given that’s about 1″ of undamped travel I’d have thought it a prime candidate for any chain jump problems but I have none.
kayak23Full MemberI don’t think you lose much by going 32t-11/36, except maybe for pedalling fast DOWNHILL…..
If you never do anything remotely technical downhill and like to get your kicks from pure speed, then a 32t front ring isn’t for you. 🙂slackaliceFree MemberStick with 3x!
Probably not what you wanted to hear, but sometimes being hip and trendy isn’t the best for all of us – a bit like 150mm stems and 300mm wide bars back in the late 80’s 😕
As you mention, 1x gearing possibly works well for those who have legs like tree trunks and lungs the size of a hot air balloon, just so they can cope with not being able to select an appropriate gear in time for the sudden rise or dip that occurs just around the hidden bend…
With 3x gearing, large shifts in ratios can be achieved easily, effortlessly and……. Quickly.
2x gearing. What’s that all about? Weight saving? Hardly, not when you take into account bash guards and chain devices. Like 1x, it removes a gear shifter from the bars that can then be replaced with a dropper post remote! Like 1x, 2x shares the same inconvenience for most of us that our bike becomes totally useless on road sections or even, dare I say, going remotely downhill because the highest gear available is 38:11, as opposed to 44 or 48:11.
Oh, maybe I need to buy myself a road bike to soothe my need for speed and wind in my hair, flies in my teeth?
This forum is often filled with talk of industry conspiracy when it comes to wheel sizes. IMO, a choice in wheel sizes is a good thing. The real industry con that is being trotted out to the masses is this apparent need for mountain bikes to have fewer gears and become less adaptable or mult-discipline through telling us that we need to have only one or two rings at the front! It’s total bollox, but at least you can all go and spend more money on converting your once very useful and adaptable bike into one that is good for a little less. Oh, and don’t forget to go off and buy a road bike!
So, please, I’m not a closed minded individual. I will gladly listen to any proposed advantages of 1x or 2x gearing that people come up with that they feel genuinely have helped them enjoy the sport more than they enjoyed it with 3x.
And please, advantages, not the usual justifications after having shelled out a load of hard-earned luka on an ‘upgrade’ that the media said was going to make me a happier person.
Mild rant over, sorry to the OP for kinda hijacking your thread, although hopefully I may have helped you make some kind of decision, that following the flock may not be in your own personal interests every time.
And it is a beautiful sunny morning 😀
EDIT: The smart money will be on the majority of recreational riders going back to triples within the next 2 years…
bikebobFull MemberI run 1×10 std middle 32 up front plus 11 / 36 rear. No going back for me, you get to be stronger and most general things are rideable. Came back from CYB and certainly all blacks and reds are doable.
Also have 2×10 on hard tail. No chain device and no probs. only ride tracks and bridle ways on HT and spend 90% of time in top ring.
For gen trail riding go 1×10, you won’t want anything more. Simple , low maintenance and a few gramskayak23Full Memberthis apparent need for mountain bikes to have fewer gears and become less adaptable or mult-discipline through telling us that we need to have only one or two rings at the front!

I agree with what you are saying but I suppose it depends on how you want your bike to adapt. I personally ride a lot of dirt jumps, downhill tracks, 4x tracks and such like, so as a result, MY version of adaptable means less complication, less chance of ripping into your legs in a crash with a toothed ring, 100% chain-retention and maybe saving a little weight.
If the sort of riding you do is a lot of xc mileage and a lot of it on road, then of course, a 3-ring setup is for you.I will gladly listen to any proposed advantages of 1x or 2x gearing that people come up with that they feel genuinely have helped them enjoy the sport more than they enjoyed it with 3x
The above (for me personally) 🙂
shortcutFull MemberI have been running 2x for 2 years now. 34,40 and 26,38 with a block to 36 on the back.
No issues with dropping the chain. I have a clutch mech and I don’t pedal backwards (no point doing that)! This may be why people drop their chains.
Riding all over the UK, on a hardtail including trail centres, rocks, Fort Will red downhill, Snowdon etc.

If you never do anything remotely technical downhill and like to get your kicks from pure speed, then a 32t front ring isn’t for you.Massively dependent on the individual and their cadence. I do plenty of technical stuff using a 36 up front. There is no way I can spin fast enough to get proper speed on a 32. Everytime I ride something like that I feel undergeared and my legs are going way faster than I’m comfortable with. Hence I’m still at 2x – I did 1×9 a few years back with 11-34 and 36 up front, great for trail centres and designed climbs but not enough in the real world for me.
2x gearing. What’s that all about? Weight saving? Hardly, not when you take into account bash guards and chain devices. Like 1x, it removes a gear shifter from the bars that can then be replaced with a dropper post remote! Like 1x, 2x shares the same inconvenience for most of us that our bike becomes totally useless on road sections or even, dare I say, going remotely downhill because the highest gear available is 38:11, as opposed to 44 or 48:11.
Only used a triple twice in the last 8 years, before that the big rings got used to scratch rocks, logs and take chunks out of my legs. I can run enough gears with a 22/36 front that I’m happy without 42. It means I have a bike that can have a lower BB but ride higher, run a bash to protect these expensive chain rings and my legs and still do what I wanted to do.
To the OP Black Spire Stinger is the cheap and easy solution to 2x with a bash.
slackaliceFree MemberYep, I’m with you on the increased height advantage that a smaller ring at the front gives when riding over logs, rocks etc. good point well made.
As is the specific riding you enjoy, although it does make the concept of an all-terrain bike a little innocuous.
Thank you.
cakefacesmallblockFull MemberThat’s it. Staying as
naturGiant intended. Not long replaced worn chainrings anyway and my big ring now has 44t as opposed to 43 following what in all fairness was a rare ding against a rock and only having caught it a handful of times on fallen small trees. I’ll still get to keep a taller gear for the odd few miles on the road to the cafe on days I don’t chuck the bike in the van.
Thanks people, no more itch to scratch.bullroarFree MemberI use 2*9 with bash on a BFe no chain device and 2*10 with bash on a Trek Remedy. Neither has a chain device and I don’t drop the chain.
When I got these bikes I set them up as 2* as I rarely used the big ring (I much prefer spinning to mashing a big gear) and it was effectively becoming a toothless bash guard anyway. I never feel the gear range is inadequate.
zero-coolFree MemberI’ve got 2×9 on my Alpine (32 on the front and 11-32 on the rear) and I find I’m under geared a lot. Mainly on the flat and downhill. I find I’m nearly always in the smaller sprockets on the cassette and its showing as they wear much quicker due to smaller.
Will be switching it up to a 34 or 36 on the front this week so hopefully I’ll use the full range of the cassette.32×32 is not to bad for riding up most things, but the granny run is pretty good for slogging up alpine climbs for an hour or more.

Why on earth do you think you need so many gear ratios (many of which are nearly duplicated)?
Like 1x, 2x shares the same inconvenience for most of us that our bike becomes totally useless on road sections or even, dare I say, going remotely downhill because the highest gear available is 38:11, as opposed to 44 or 48:11.
‘Totally useless’ – yeah. 🙄
Do you just enjoy pedalling really hard down a fire road? Or are you just super-awesome?
kayak23Full MemberThis forum is often filled with talk of industry conspiracy
I actually think it works the other way too. For years and years, most of the ‘Industry conspiracy’ talk about new bikes was about amount of gears. You’d hear people say,’How many gears has it got?’, equating more gears with better bikes.
As a result you saw most people riding bikes with 21 gears and upwards who had no need for them whatsoever and had even less chance of ever setting them up to work if anything went wrong.I think 1x drivetrains are largely a good thing for ‘the masses’, but of course, it all depends on what and how you ride.
It’s true though, I often do spin out on my 32t-11/36, but then it’s a compromise I’m willing to accept.
nickcFull MemberMoved from 3×9 to 2×10 (40/28 and 11-36) with a clutch mech, no chain devices, no dropped chains, it’s made the grand total of sod all to my riding.
clubberFree MemberI was using 2×9 and then 2×10 with just a small/middle ring and no bash ring. I did use a double specific SLX mech though which seemed to hold the chain better than a standard mech.
I’m on 1×10 now though and happy with that. 11-36 though.
As you mention, 1x gearing possibly works well for those who have legs like tree trunks and lungs the size of a hot air balloon, just so they can cope with not being able to select an appropriate gear in time for the sudden rise or dip that occurs just around the hidden bend…
I’m really unfit at the moment and generally a spinner but I find 1×10 ok even on longer rides that I really don’t have the fitness for – the key is to get the ratios right, surely?
iaincFull Memberjust gone from years of triple to 2×10 on a new build Soul. I have 11-36 on the back, 24-38 on the front and a clutch mech, all new XT. Can’t say I am missing any gears that I dont have, and I am definately not missing hitting the big ring on logs and rocks. I do find I need to think a bit more about shifting, probs just getting used to it, and I have noticed that the rear mech gets used to pretty much its full extremities if inadvetently ending up big/big or small/small, which is easier to end up in that with triple.
Chain has never dropped, and if I pedal backwards in big/big it climbs down the cassette, but I wouldn’t do that in ‘real life’ anyway

Loads of extra ground clearance. No jaggy big ring to cut your legs up.
Single ring is similiar to singlespeed- it’s not an improvement exactly (though, for hard use the superior chain retention is good), it’s just a way to make your riding a bit different. I really like it. I also really like not having to fit and index front mechs!
clubberFree MemberI don’t even think it’s different. I would just ask why use a triple or double if a single ring is sufficient for what/how you ride? Using a triple just provides me more gears that I don’t use or need. For me, the benefit is that it’s simpler. I guess it’s lighter too but that doesn’t really bother me.
Otherwise, why don’t you fit a quadruple?
OK, I’ll accept that if you’re buying a complete bike you may not want to mess with it and change to a single but I reckon most of us here build up our own bikes to suit us rather than going standard so it’s pretty straightforward.
stu1972Free Member1 x 10 11-36 34t is the sweet spot for me, both for fitness and the terrain I ride.
I originally set out with a 36t on the front but found it hard work. Now that I’m fitter i’ll probably switch back.
I use the BB mounted Superstar Components chain guide. It’s never given me any bother or dropped chains and I don’t exactly romance my bikes round a trail !
cookeaaFull Member2X9 on My HT (SLX mechs like you OP) 11-32 + 22/36/Bash and no chain device at present, The range is 18 – 85 Inches which suits me (YMMV) I did take a few links out of the chain to increase the tension a bit though, on my Previous build I used almost the exact same draivetrain but with a bottom roller guide.
TBH I haven’t dropped my chain very much since leaving the device off maybe once every 20 rides and it only goes off the bottom so a pedal strocke or two pulls it back on. while I keep meaning to buy and fit stinger, I’m really not sure I can be arsed now, I could probably improve chain retention a shade more by removing a couple more links too.
Yes the Bash effectively acts in the same way that a big ring would to help keep the chain from going off the top, except it doesn’t bend when bashed (clues in the name really), and it has takena couple of knocks.
I have thought about ditching the Bash as a weight saving measure and may well do so at some point, I’d possibly re-fit a bottom guide roller at the same time, I don’t really know, it would negate the weight savings a bit, I think shortening the chain by a few links is probably worth doing if you’re ditching the big rig though, if 10 speed is an option it’s probably worth looking at Shadow +
Having said all of that, there’s nothing really wrong with using a triple, if it provides the gearing you want and your not twatting that 44T into rocks all the time then just stick with what works for you…
dantsw13Full MemberBoth my bikes have had 2x for the last couple of years. It really simplified my shifting – only 1 shift either way, and less of it! On a triple, so much of the rear cassette is unusable on each ring, due to the extremes of the chain lines. add to that the duplication of gears, and I doubt there were more than 20 gears usable anyway. With a double, all of the 20 are usable.
I thought I would miss the Granny gear, but Ive now realised I only used it because it was there.
Ive just set up my Heckler 1×9 with a 32T on the front, and full chain device. It is for the Alps, and i was a bit worried about the lack of climbing gears. I took it for a 40k local test ride on sunday (Local roads, steep hills and Bedgebury red route) and was pleasantly surprised – I got up everything.
traildogFree MemberWhenever you met a group of roadies, the conversation used to always turn to gear ratios. As a young mountain biker with 21 gears, I never understood it until I started road riding – you never quite had the right gears on the bike and there was always some sort of compromise.
Now it seems Mountain biking has gone the same way. In terms of range of gears, a triple is the best choice – you can spin up steep climbs when tired and you can bomb along the road at daft speeds and still have gears to spare. However, as the longer chain slaps around a bit and occasionally jumps off the gears you want, and most annoyingly, the dinner plate sized chainring bashes on rocks and end up searching for a more sensible sized 40t…. Or you take it off, you only really need it for the road and you can make that compromise…
So then you’re left with 2 rings, but the chain slaps worse because you no longer tension it with the big ring, large cassette sproket combo as that’s too smaller a gear. So you try experimenting with chain retention devices…
Which eventually leads to 1 ring. Which is great, it’s silent, you never lose the chain, you find you don’t have to worry about which front gear you’re in….And yet you don’t *quite* have enough gears. You turn into a road talking ratios, grinding up steep hills slowly etc. when you could spin up quicker.
So it’s all compromise. My trail/Enduro bike is a 1×9 (would be 10 if I had the cash) as I love the single ring setup. My xc race bike is a triple because I also use it for longer events and like the granny when I’m tired, but also want the speed on the road. Very excited by Srams idea of single ring and hope Shimano will come up with something similar soon.
quintet100Free MemberHi
I run 1 by 10, 32 oval up front with 11-32 at the rear.(29er). Xtr through out. It’s all I need, done trail centres, big hills.
Best set up I’ve had.wobbliscottFree MemberIt all depends on the type of riding you do. For me it is all about steep shortish climbs and shortish descents where you tend not to pedal, so I have little need for the higher gear ratios and it is just cleaner, simpler and neater to ditch the front mech. I had a 2×10 on my bike with no chain retention and found i rarely used the larger chainring, so I just ditched it (replaced with a bash guard) and ditched the front mech and associated gubbins. I had no problems with dropping the chain, even over rocky sections, but when my X7 mech snapped on me I got an x9 type 2 rear mech. I could do with a slightly larger chainring but as I don’t really use the higher gears that much, as the descents are fast enough especially if you learn to pump, I don’t see the point in gooing for a larger chainring. On the steeper climbs I prefer to run a lower gear anyway as it gives you the ability for those extra spurts of accelaration to get over rocks and steps which you wont have if you were to listen to some on here and ‘MTFU’ and push a stupid high chainring up front. There is some willy waving done in that department as to who is pushing the biggest chainring.
buzz-lightyearFree MemberI have :
A Sov HT with 1×9 and a top device
A TranceX with 2×9 and a bash
A Tracer 275 with 2×10 with a clutched mechAll of these work well for my riding (UK and Alpine singletrack, moderate DH tracks, rocky stuff etc), but I’m not a big jumper.
I tried running the Sov without a top device but as soon as the trails got proper rough, the chain would bounce off the bottom and fall off the top. The top device stops it falling off the top so that it re-seats on the bottom as soon as you pedal again.
I ran the TranceX without the bash successfully in the UK, but I would de-chain regularly on a trip to Liguria. The guide (Ady from Riviera) handed me a bash to put on and it seems to stopped the problem.
The clutched mech on the Tracer 275 is a miracle. I’ve given it hell and the chain just stays on.
The 1×9 system on the Sov is perfect for shorter local rides in all weathers, but I’ve managed weekends away to Brechfa/Cwmcarn. I think I manage because the bike stand-up sprints so well. But Im OK with a bit of pushing when the legs give up. I mainly use this for local riding though.
I have considered running 1x systems on the TranceX and Tracer as they are both pedalling-friendly suspension systems. But these are bigger travel bikes for all-day all-mountain rides, especially the Tracer which is 30lb. And the TranceX doesn’t tolerate standing-up sprint pedalling very well. It’s much more sensible to have a granny ring you can sit and spin efficiently all day, even when you are tired, on this kind of bike/riding.

It’s a terrible excuse to get off and walk, hasn’t happened to me once yet 🙂
I_AcheFree MemberThe smart money will be on the majority of recreational riders going back to triples within the next 2 years…
Yea good one. I have been riding 1×8/9 since ’98, it just suits my riding. I can’t see myself ever going back to 3x apart from on a road bike. Yes I have 2×9 on my HT but I rarely use the granny and as I don’t need to ride my MTB on the road for more than half a mile I don’t need a 44t. If you need a 44t for DH off road you’re either on a straight boring fire road or you need to start looking for sponsorship.
richmtbFull MemberI’ve been 2 x 9 fir more than 5 years.
Its just works. No jaggy big ring to cut me and bash on rocks. Changing the middle to a 36T ring covers most of the missing larger gears.
Still have the granny ring for long draggy climbs of which there are plenty in Scotland.
Bash / front mech and a shortened chain works to keep the chainn where it should be
buzz-lightyearFree MemberThe smart money will be on the majority of recreational riders going back to triples within the next 2 years…
Err why? I really never used the 44t off road. I was barely out of it when on the road, but I have road bike for that now.
Oh do you mean people riding hybrids on towpaths?
monkeychildFree MemberMy new(er) bike has 2×10 and I think it’s amazing. GOing back to my triple on the Trance feels wrong IMHO. I did run 1×9 on my old bike but got fed up of dropping the chain 🙁
