I think it's more the relative change in "fashion" (for want of a better word although "set-up" might just as well apply).LittleGreyCat wrote: ↑14 Feb 2025, 2:27pm So as I said, I am puzzled as to why some riders seem to decry using the full range of gears available.
Back In The Day™ when riders had a triple (often 30/39/53 for road / touring) and maybe 7 or 8sp at the back, it wasn't uncommon for cassettes to start with a 12 or 13. As chainrings have generally decreased in size and gone more to 1x and 2x, the way to get the same / similar range was to expand the cassette both to smaller cogs at the high end (Shimano now start with 11 as default, SRAM start with 10 and Campag (on their 13sp Ekar) start with a 9), and to bigger cogs at the low end (previously most cassettes would top out at 28 max, now even road bikes go up to 32 or 34, gravel and MTB can go to 50+).
So for those riders that refuse to move from a triple for whatever strange historical reasons, they're now stuck with 11-up cassettes and the unwanted high gear is upsetting for them. Obviously people then come along and start going on about "custom cassettes" usually involving chopping up bits of aluminium to make your own shims and spacers which is frankly way too much like hard work for not much gain.
Some folk get obsessed by the gear range (obviously bigger range= better, right?) so they'll go on about how only 3x gives them stupid low + bonkers high gears without ever really considering if they actually use all those gears, the massive cross-over range in the middle of if having a 550% range is really appropriate or necessary. Besides which, range is only a consideration if it's the correct range. No good having 30 gears but only the bottom 10 are usable because the chainset is too big or 30 gears but only ever using the top 6 because you ride entirely on flat tarmac.
To be fair, that latter point was a big failing of bike companies in the past as they all went for more gears cos more gears = cooler. I remember selling "commuter-ified" MTBs when they became A Thing - they looked cooler than hybrids, way more bombproof than road bikes so we sold loads. But they still had MTB gears (triple chainset) so it wasn't uncommon for them to come in for service with the outer ring and the smallest 4 cogs trashed and the inner and middle chainring (and the larger half of the cassette) immaculate. Big range of gears but entirely shifted too low.
Bottom line is that if you choose your groupset appropriately, 99% of riders should be able to get a spot-on range from any off-the-shelf componentry without having to resort to daft customisation. Problem is that many riders, especially the more traditional / older end of the spectrum, are still wedded to triple and as a result are hitting the compromises of never being able to fully use a big cassette because there's no mech long enough to cope with an 11-40 cassette on a triple chainset. Better off with an 11-40 and a 30/46 double chainset rather than trying to achieve wide range by a 28/38/48 and a 12-28 cassette.
