The SRAM Eagle XX1 12-speed group as well as the newly launched Shimano XTR M9100 are the object of desire for thousands and thousands of mountain biking enthusiasts. The problem is that in order to enjoy a 12-speed drivetrain it is necessary to invest a good amount of money, something that not all cyclists have the possibility or desire to do. What are the two most economical options to switch to 12-speed?
There are several 12-speed conversion options on the market. But when we talk about economical options it is about investing as little money as possible to achieve a complete conversion at 12 speeds, something that can only be done by changing the essential components. What parts need to be changed? Rear derailleur, cassette, chain and push shifter, taking advantage of the cranks that each cyclist has installed and the hub of the rear wheel, without the need to change the driver body.
SunRace MZ-12 Speed
SunRace, one of the most popular brands when it comes to renewing a used component of the drivetrain, has its own 12-speed group in its catalogue.

The total investment remains at 228€ assuming the price recommended by the brand, with the added advantage of being compatible with standard wheel hubs for 9/10/11 speeds.
