1x Set Up?

[Philip Barrett]

Anyone doing a 1x on their Rivendell? Any chain line or other issues?

[Erik]

I am running a 1x on my MIT Atlantis.  It's worked flawlessly so far.  I'm running a Wolf Tooth 34t chain ring on a Silver triple crankset in the middle position with a Silver guard on the outer ring.  It is a nearly perfect chainline.  I'm set up with a massive SunRace 11 x 50 cassette in the back with a SRAM GX 11 speed and a  SRAM trigger shifter on. the bar.   I wanted to do a set up on this bike that differentiated it from my Appaloosa.  So this one is more on the mountain / hilly-bike side of things.  I really like the simplicity of 1x, particularly for off-road.

I have a 1x11 on my Joe Appaloosa.  I did it to lighten the load, but in reality, I just used to go up and down the back 8 cogs and kept with my middle chain ring in the front.  Analog did it and put indexed shifters instead of friction.  I haven't had an issue, but have only put about 300 miles with that new setup.    I don't understand much of it, but love the setup.  The details are here.   https://groups.google.com/g/rbw-owners-bunch/c/pWpMrkiVUlk/m/eVByOom6CQAJ

Analog is setting up my Platypus similarly. from what I understand, I get nearly the same range and if I was willing to go with a 1x12, I would get the same range as I did with my triple up front and eight in the back.  A bonus for me is I could have a pant guard, because it is both practical and classy looking.

My Susie is technically 2x because of the granny ring but there's no front derailer/shifter and it's usually in the big ring. Sugino XD600 cranks, 36t in the middle position and a Silver pants guard, 12-36 9-speed cassette. Works great, current long-stay Rivs are good with 1x because that long chain doesn't do a sharp bend in the high and low cogs.

Unless my riding changes significantly, I'll never go back to multiple chainrings.  

When I built up my Hunqapillar, I took it to an LBS for the rear derailleur adjustment and they also fiddled with the chainline, using various spacers on the crankset/chainring junction.  I run it with a Deore trigger shifter and no problems, at all.

Talked to James at Analog yesterday & have a Wolftooth 42 headed my way & the Blue Lug 42T chainguard for the Silver.

While I am happy to pass on most newer bike tech, clutch derailleurs and narrow-wide single front chainrings are awesome. I have never dropped a chain even in the roughest stuff, and the sound of the chain smacking your chainstay is no longer a thing.  

2x or 3x are still the way to go if you carry varying loads but otherwise I struggle to see much reason for the extra complexity.

I went compact/granny 2x on my Riv Road, mainly because I wanted a little more old-timey, non-mullet-looking drivetrain on it. But just piping in to add to the voices saying that 1x is easy and fun, as long as the overall gearing range and the gear progressions work for you.

You can easily get away without using narrow-wide rings or clutch rders if you're not doing a lot of rough stuff, or just to try it out with what you brung to see if it works before dropping buck$ on the n-w/clutch stuff. I don't find chainline to be much of an issue, esp with modern flexier chains. I'll often throw a std ring on the inner position of a 2x crank and use a BBG chainguard on the outside position. Until I got back into doing some vintage builds where 1x didn't work, I went for a couple/few years without having to shift a fder, and I didn't miss it at all.

The many grains of salt necessary when considering my bloviating is that I'm not carrying much in the way of gear, and I'm not setting up any modern-ish Riv-ish frames with reeeeeeaaaalllly long chainstays or clearance for mega-wide tires. So YMMV. And my bikes that spend most of their time off asphalt will almost invariably have n-w/clutch drivetrains.

I'm running 1x11 on my proto-Appaloosa.  It works flawlessly and I enjoy the simplicity.

[Philip Barrett]

If you don't mind, what derailleur & cassette are you using?

Word is that the SRAM 11-speed will fit on Shimano 8/9/10 speed hubs like the Deore.

[lconley]

Shimano Mountain 11 speed works on a Shimano 9 speed hub. Shimano Road 11 speed will not. The mountain cassettes have large inner cogs that can overhang the hub flange (the outer 3 cogs are connected) and thus use the narrower 9 speed cassette spacing. The road cassettes have smaller inner cogs and cannot overhang the hub flange, therefore they require a wider cassette spacing. The idea behind the mountain cassette is to have wider spacing between the flanges allowed by the narrower cassette and less dish, therefore having a stronger wheel.

Thanks for the info - it looks like the CS-M7000 series would be fine then?

And if you stick with the same 7000 series of derailleur & shifter you've obviated any mismatches.

[Jason Fuller]

Here's ye olde Bombadil with my newly added "fake outer ring" aka chainring guard, which is covering a 34T narrow-wide ring by Raceface.  Cassette is 11-42 and this gives me enough low end for real steep stuff (which happens a lot around here) and enough top end to pedal out on pavement descents - and this range is so well optimized for my needs that I use every gear very regularly, but rarely need more.  If this was a more road-oriented bike or I didn't live in the mountains I'd probably swap to a 38T or maybe 40T up front, but I'd always prefer to run out of top end than low end.  

[Larry Charlton]

It's a Shimano 105 derailleur and a CS-M7000 11-42 cassette.  Yes, that's mixing road and mountain components but I have never had an issue -- now going on 4 years and a couple thousand miles.

Can I ask what BB Spindle length you're running here? Looking to 1x my Waterford Atlantis. 

Cheers!
