No, mountain bikes don’t have silly lows for what they are designed to do. In my opinion, they have too high low gears. The 1x craze makes for bikes that have gears that are low enough but force the rider to spend a lot of time coasting on downhills.
As for derailers, people tend to give up on them because they don’t understand them. They really are simple mechanisms that are fairly easy to work with as soon as you understand that the cable and cable tension is everything to making them work well.
Regardless, 48/38/28 has the MOST ever useless duplicates, like 11 or 12 so. LOL That is why they went to 50/39/30 that I had on a hybrid. I did find such hills in Vancouver BC, Calgary, Seattle, Tacoma on my tour, and SF. A bunch of these hills I wouldn't ride even on an empty bike and could only barely just push the loaded bike. Must have been 16 - 18%. WTF There are a few here too going up the 200 foot river cliffs. Expecting bike companies to cater to such extremes is laughable. . So is saying you can't push the TOP gear on FLAT land.... If I can't go 4 mph I likely PUSH.
I’m not sure what you are trying to say...”like 11 or 12 so...Huh?...but the 48/38/28 doesn’t have that many “useless duplicates” nor is the 50/39/30 any better.
When you compare the two, there really isn’t that much “overlap” at all. It’s difficult to get all the gears but that’s not necessarily how gearing is supposed to work. To ride a close double...which is all a triple is with an extra low gear...you shouldn’t look on it as being a linear shifting system but as a way to transition from high range to low(er) range without huge jumps between. That’s the problem I have with wide range compact doubles
which don’t have duplicates but do have shifting patterns that result in huge jumps between the ranges. If you play with the RPM part of those linked gearing, you’ll see that dropping from the outer ring to the inner ring results in the need to increase RPM to ridiculous levels to keep up with the change.
1x systems give you the choice of a
high range or a
low range but nothing in between. Yes you can go with more gears and have smaller steps but it’s still limited to the same choice. A very large cog on the cassette can give a lower low but the high still suffers. I can
match or even exceed the range of a 1x with a higher high and a lower low with little effort. I have the exact gearing as in the last link on my touring bike as well as similar gearing on my mountain bike and they work flawlessly with derailers.
Otherwise, 90% of cities only need a 3 speed. I took a 12,000 mile drive last summer with my 3 speed on top.
In Canada I only found 1 or 2 steep hills in each city, easily avoided. No problem in Toronto, Montreal, Ottawa, Quebec City. Any IGH 8 would do.
Look at any video of west Europe and you will maybe find 1% defailleurs. LOL
Actually on my tour with 21 to 115 GI Rohloff14, The top was used far more than 2nd, 3rd and 13th. And I DID use 14th on a flat freeway with a 20 mph tail wind. I was doing 27 to 30 mph.
90%? Do you have data to back that up? Denver, Las Angeles, San Francisco, Seattle, Portland, Alburquerque, Santa Fe, Salt Lake City, etc. are examples against this “90% of cities being flat”. Canada and the northern central US aren’t exactly the best places to find hills. They kind of got ground down a few thousand years ago. Drive through the Inner Mountain West and see how many towns and cities have hills you can avoid.
