Now I remember! If some people _think_ they can benefit from it, we're not allowed to discuss what anyone else may think. IOW, comparison of real benefits and detriments is strongly discouraged here. The linked article is about a kludge accomplished by someone who actually wanted 1X on his clearly custom bike. 1X has the benefit of being a rock-solid set-up in rough terrain. You should read about it. https://tinyurl.com/v3un986 I tried to read that, but all I got was a photograph. You constantly bad-mouth basically anything you don't own and with which you have zero experience. I have test ridden a couple 1x bikes, but not for long. The longest was when the president of the local mountain bike club met me in our forest preserve to look at possible trail work projects. We traded bikes for maybe half an hour on the back trails. His bike (I don't recall the brand) was super light, rigid, with probably 4" tires, disc brakes and 1x transmission. It shifted very nicely, but when I asked about it, all he said was "I never have to worry about a front shift." OK, for the twisty, lumpy single track trails in this little forest I could see that being nice. (The only time I ever broke a chain was in there, trying to hit the granny gear for a quick super-steep rise.) But otherwise, ISTM front shifting is a big benefit. Look ahead, see "this is going to be steep" and execute one front shift that gives you a whole range of low gears, with the lowest being lower than a 1x could get. (I think my lowest is a 24 - 34 and it can be shifted with very ordinary derailleurs.) Meanwhile, people who have owned doubles, triples, 1X, IGH, etc., etc. make reasoned decisions to run -- or not run -- 1X. They're not crazy. They're not deceived. Guys who are kludging expensive SRAM systems obviously believe in the superiority of 1X, just like you believe in the superiority of triple cranks and cantis -- crap I dumped long ago and never looked back. But can't we discuss? When is 1x more sensible than 2x? Or 3x? When is it not? What are the advantages and disadvantages? -- - Frank Krygowski |

If it has no benefit for you don't buy a 1x11/12 set up. For me it has no benefit so I stay with 2x11 set ups. Why do you say 'if some people 'think' they can benefits from it'. Are you saying that they lie if they say so?

I know Duane won't answer this, but: Let's be realistic. People "think" different things at different times. Much of what they think is influenced by what they read or are told is the latest best thing. It's an unusual person who sits down with all the alternatives and makes a conscious rational choice. If you start at the pre-history of front chainrings, people thought 1x was great as long as you could shift in back. Then someone invented 2x, and people thought that was obviously better. Then bike tourists got 3x and it was perfect. But racers would never use that, maybe because shifting to the middle ring took finesse (although that was a problem solved on millions of cheap bikes). Or maybe because a chainring weighs 75 grams? Or its aero drag is a micropound? So racers stuck with 2x, some with 52-47 or 52-49 half step to get small steps and no duplication. Most settled on 52-42 or thereabouts with lots of duplicate gears and toughed it out on hills, grinding up at slow, standing cadence. Then they went to "compact" - still 2x, different choices in rings. Toughing it out became unfashionable and cadences jumped on uphills. Then to get smaller steps or more gears, racers added rear cogs. Each added cog was "thought" to obviously be better than the last count, because, well, "more!" Except now it's suddenly "Less!" Not as a desired outcome; but instead as a side effect that suddenly doesn't matter. It seems strange. So yes, 1x is what many people are now thinking. But it's very hard for me to believe that through this change - or all the ones that came before it - nobody has said "Hmm. This really isn't any better for me." IOW, there have to be detriments as well as benefits. Both should be open for discussion. Saying "People just like what they like" is not very instructive regarding technology. -- - Frank Krygowski |

What are the advantages and disadvantages? 1x makes sense because now you never have to try and shift the side of the chain that is under tension. So for people that want absolutely bulletproof shifting even when applying full torque, I suppose it makes sense. It also “decomplicates” the mental model of the gearing system. There’s only one lever, and you can only go up or down. There’s no “shift up one in the front and down two on the back” gyrations required. The price you pay is a reduced gear range, which you can somewhat compensate for with a 9 tooth gear on the rear cassette, which then requires other compromises. Modern shifters have made front shifting a lot better than it used to be (and I hear that Di2 front shifting is real nice), so I don’t see 1x as a Glory Hallelujah type of breakthrough for the average cyclist. As a touring/commuting kind of guy, I’ll still to my triple FD, since I usually know what’s coming up ahead and I appreciate the wide gear range. |

It looks like he ended up with about 40 - 52 or about 21 gear inches, or 1.66 meters development. If he had instead added a 30 tooth chainring and front shifter, the original ~42 tooth in back would give him an even lower gear using very standard parts. A 24 chainring would give much lower gears. So, easier and more effective. IME experience, that would have made much more sense, perhaps because I have front shifting problems approximately never. Yes, his MMV, and yours might as well.

Um... why? - Frank Krygowski Why? To get rid of the FD and front shifter and avoiding to shift front and back in critical race situations. Some people think they can benefit from it. Oh. Now I remember! If some people _think_ they can benefit from it, we're not allowed to discuss what anyone else may think. IOW, comparison of real benefits and detriments is strongly discouraged here. -- - Frank Krygowski He don't shoot the messenger. You asked a question I tried to answer politely. If it has no benefit for you don't buy a 1x11/12 set up. For me it has no benefit so I stay with 2x11 set ups. Why do you say 'if some people 'think' they can benefits from it'. Are you saying that they lie if they say so? Lou That's what you get for trying to "discuss" it with someone who is just trolling.Â* Otherwise he would have realized that you answered his question to begin with.Â* To avoid shifting the front derailleur in critical race conditions.Â* Could be an important consideration for some people. I know Duane won't answer this, but: Let's be realistic. People "think" different things at different times. Much of what they think is influenced by what they read or are told is the latest best thing. It's an unusual person who sits down with all the alternatives and makes a conscious rational choice. If you start at the pre-history of front chainrings, people thought 1x was great as long as you could shift in back. Then someone invented 2x, and people thought that was obviously better. Then bike tourists got 3x and it was perfect. But racers would never use that, maybe because shifting to the middle ring took finesse (although that was a problem solved on millions of cheap bikes). Or maybe because a chainring weighs 75 grams? Or its aero drag is a micropound? So racers stuck with 2x, some with 52-47 or 52-49 half step to get small steps and no duplication. Most settled on 52-42 or thereabouts with lots of duplicate gears and toughed it out on hills, grinding up at slow, standing cadence. Then they went to "compact" - still 2x, different choices in rings. Toughing it out became unfashionable and cadences jumped on uphills. Then to get smaller steps or more gears, racers added rear cogs. Each added cog was "thought" to obviously be better than the last count, because, well, "more!" Except now it's suddenly "Less!" Not as a desired outcome; but instead as a side effect that suddenly doesn't matter. It seems strange. So yes, 1x is what many people are now thinking. But it's very hard for me to believe that through this change - or all the ones that came before it - nobody has said "Hmm. This really isn't any better for me." IOW, there have to be detriments as well as benefits. Both should be open for discussion. Saying "People just like what they like" is not very instructive regarding technology. -- - Frank Krygowski Open for discussion? Why? The original post was not about single versus double or triple cranksets. You asked why a single crankset for the obvious reason being not your choice. Despite that people tried to answer your question. And now we get a lecture from you. Nice. Today you can get single, double or triple cranksets with all possible chainring combo's so 'people like what they like' should be good enough if they thought their choice over. The downside of a 1*11/12 setup is the limited gear range or big jumps between the gears which can be perfectly acceptable for some people in certain riding conditions. So what is your problem? My original question related to a guy who took a pretty expensive derailleur, dismantled it to use its cannibalized parts on another such derailleur, so he could use an enormous 52 tooth cog in back. He also had to kludge around to build a suitable set of cogs. Apparently, this was mostly to get a lower gear. It looks like he ended up with about 40 - 52 or about 21 gear inches, or 1.66 meters development. |
