What does a 12 speed bike mean
On the back, the 12-speed cassette starts at a 10-tooth cog, and increases by 1-tooth per cog. The overall result is that you can reach a higher resistance at the top-end, and your smallest gear is even easier to push.15 Sept 2021
Which is faster 11 speed or 12 speed
Since the 12-speed cassette has the same total width as the 11-speed, the space between cogs is narrower. This leads to “faster” shifting since the derailleur doesn't need to move as far to switch gears.3 Nov 2021
Is a 12-speed bike good
And thanks to improved materials and tolerances, they're also much more reliable overall, even if they can be a little finicky compared to those 8 and 9-speed systems. 12-speed drivetrains pretty much killed the front derailleur as well, especially after 11-speed showed that maybe we didn't need them after all.16 Jul 2020
Why is 12-speed better
Since the 12-speed cassette has the same total width as the 11-speed, the space between cogs is narrower. This leads to “faster” shifting since the derailleur doesn't need to move as far to switch gears. Obviously, this is all dependent on cadence, and a higher cadence will maximize the advantage.3 Nov 2021

Can you put a 12 speed cassette on a 11 speed hub
Yes you can run a 9/10/11 & 12 speed cassette on a shimano free hub, a Sunrace 12 speed will fit.
Should I upgrade to 12 speed
You probably shouldn't. A new 12 speed drivetrain is very expensive at retail prices. Unless your bike is nearly new with modern geometry, modern brakes, etc. It would be much cheaper to just replace your old worn chain, cassette and chainrings.
Can I upgrade to 1×12
The fairly recent crop of 1×12 drivetrains promises to deliver new levels of performance and a much higher range (more on that later), coupled with the decreased complexity and weight of a 1x drivetrain.29 Oct 2020
Will Ultegra go 12 speed
Like Dura-Ace (you can read our full news story on Shimano Dura-Ace R9200), the new Ultegra road bike groupset is 12-speed, available with rim or disc brakes and semi-wireless (in the disc brake variation). Crucially, there's also no mechanical option for Shimano's new second-tier groupset.31 Aug 2021
What is happening with Shimano
Shimano shared that it's been forced to temporarily shut down one its Malaysian factory. Due to COVID health requirements in Malaysia, Shimano's factory had already reduced to 60% operating capacity. Now Shimano, reports BRAIN, has shut it down completely.11 Jun 2021
