While this sounds great already, I would like to also mention the Pinion gearbox that can be integrated into the bottom bracket area of the frame. Yes, it is even heavier and also expensive (hard to compare with the Classified as it is built into premium wheels, and the Pinion is integrated into premium frames). But on its own it provides a 600 % range — so more than any derailleur combo — with a belt instead of a chain. That means no fragile derailleur occasionally going out of alignment, no lubing and cleaning — just hassle-free riding.
Or, if to combine the Pinion, just for laughs, with a derailleur and a 10–52 cassette, we could get a total range of 3,120 %. Not that it was not enough still, but we could actually add the Classified hub to that combo as well, so that we’d have 4,460 % range. I have no better way to end the post other than with this video
