Am I the only one who runs 32/11-40 1*10 and sneakily leaves the 25gm inner ring on in case of leg failure (I’ve never used it, but nice to know it is there!) but with no front mech.
Just my personal opinion, and I may be wrong and a bad person but I think that is ridiculous. I would mock you publicly if I rode with you. Commit!! 😁

Don't know but I like the idea - Id do that if I was running 1x10
running 30/10-42 1x11 gives me the same high gears but with more of a bail out option. If I run out of gears in this setup (rarely) Id be quicker walking.
Ianpv,
i do that, but i also left the front mech on too.
and a remote operating cable.
and a super special lever in the bars to pull said cable.
this has the added bonus of giving me the ability to swap between front rings whilst actually moving too 😀
why would you want to do that?
If you are so knackered that you need the granny ring then getting off the bike for a minute is a good idea
Getting off for a few minutes Is a good idea.
IF you can walk, which I can’t for any more than about 30 yards.
however, i can quite easily cycle those 30 yards, although only at around walking pace.
Yes but an experienced and skilled rider soon learns not to cross chain and maintain a good chainline. 1x wins out on chainline for beginners and those with no mechanical sympathy. But not the majority of riders I would say.
I would suspect that a 1x setup is probably worse for chainline than a 2x setup ridden without the extreme gears. I'd probably need to do some maths to see if this is the case or not.
BTW, there are two groups of riders out there - those that cross-up gears on a 2x setup because they have no mechanical consideration and those that know that for a 2x setup, it actually makes very little difference so cheerfully cross their gears anyway. It's not like with a 3x setup where there was a pretty extreme chain angle - modern 2x setups are quite happy to run crossed up with no ill effects.
Or, to put it another way, you'd be better off making sure your transmission is clean and well lubricated instead as this is far more likely to have an impact on wear than running crossed gears periodically on a 2x setup ever would 🙂
Practice I suppose.
Practice and knowing what gear you are in and what gears you have.
Also, it's quite easy with the more compact cassettes as it's almost always one at the front and two at the back to get to the "right" gear when you are in those middle 6 or 7 sprockets, the bigger cassettes, it gets a bit less clear cut. As it could be 1 and 3 for a couple of the shifts, right in the middle of the cassette.
But like i say, i've not looked at it much. Only been playing with 11 and wide range cassettes for a couple of years, as i've not been able to race (barely even able to ride until end of last year.)
And on 2x i've never worried about cross chaining, especially when you go to 29er or full suss, the stays are so long and compared to the old school XC 26" wheel bikes i started out on, it's not worth worrying about.
You have a more optimistic view of the majority of riders than me! I don’t think a lot of people I ride with pay that much attention.
One of the myriad of reasons for the increasing popularity in 1x systems, and eventually gearboxes/hub gears. One you don't need to think about, at all. The other, you barely need to service either.

No. I ride socially with a couple of guys who do this. One of them takes great delight in doing the downshift on the move, with his toe. Upshift is impossible due to the narrow wide ring!
Just my personal opinion, and I may be wrong and a bad person but I think that is ridiculous. I would mock you publicly if I rode with you. Commit!!
haha. Fair enough. My XC/winter hardtail has 30t chainring and a standard 11/36 cassette on 29" wheels, surely that counts as commitment!
Ianpv,
i do that, but i also left the front mech on too.
and a remote operating cable.
and a super special lever in the bars to pull said cable.
haha again, and also fair enough. But on that bike (my trail bike), the clutch mech/narrow wide chainring retention bonus and near silent operation outweigh having a shifter that I never use, and I can fit a bigger tyre on the back with no mech in the way. Much easier to clean, too.
My XC suspension bike has 2*10, so I clearly can't make my mind up.
I would suspect that a 1x setup is probably worse for chainline than a 2x setup ridden without the extreme gears.
Yes. Standard 1x chainline puts the single ring in the same position as the outer ring of a double (~ 50.5mm), so 1x lowest gear is as bad as riding big big.
If you use a lower chainline and put the chainring closer to the middle you get better overall chainline, but it's still a bit worse in top and bottom gears than 2x is in top and bottom gears.
