My opinion, not NSMB’s opinion: I think 10t cogs are silly - and I think, from what I’ve read and heard in the past, that Shimano agreed with me until they needed a reason to justify MicroSpline. Proven loss of efficiency etc. I don’t see any reason to go 10-45t over 11-46t with a slightly larger chainring. Or for that matter 12-47t or etc. I’m totally down with the 450% mountain bike drivetrain and agree that for real MTB usage the tight gaps between ratios aren’t desirable. Ignoring the intended conversation starter that is this piece about 5-spd, I’ve had awesome results with SunRace’s 11-46t 10-Spd cassette and would have a hard time personally justifying the expense to “upgrade” to more ratios or a wider range.
