Can I use Tiagra cassette with Ultegra?

Are Sora and Tiagra compatible?

Shimano’s compatibility documentation says there is no compatibility between components of groupsets of different ‘speeds’. E.g., there is no compatibility between 3×9 or 2×9 Sora and 3×10 or 2×10 Tiagra.

Can I use a Tiagra cassette with 105?

If you go for Tiagra you can’t upgrade to 105 one component at a time because 10-speed and 11-speed drivetrain components aren’t interchangeable. You’d have to upgrade most of the groupset components at once for optimum performance.

Is GRIA Tiagra compatible?

Shimano GRX 800-level components and 11-speed GRX 600-level components are compatible with current DURA-ACE, ULTEGRA, and 105 road groups. Shimano GRX 400-level and 10-speed GRX 600-level components work great in conjunction with the 10-speed Tiagra road groupset.

How many chainrings do you need for a tiagra?

You can also buy Tiagra with a triple crankset, three chainrings (50-, 39- and 30-teeth) that, along with the 10-speed cassette, provide 30 gearing combinations. The 105 system, like most higher end groupsets, is only available with two chainrings at the front.

How many teeth does a tiagra sprocket have?

You can buy a Tiagra cassette that goes up to 34 teeth on the largest sprocket. As part of a compact chainset, this will be able to get you up even the most offensively-steep of ascents. Still, some people are always going to want more gears. If you want 11 of them, then you’ll need to go with 105 (or Ultegra or Dura-Ace).

Is the Shimano tiagra a 10 speed system?

Shimano Tiagra is firmly a 10-speed system, reducing the number of potential gearing combinations by two. This may or may not be a problem for you. There is a marginal benefit in having an extra rear gear.
