Title: Does 12 speed 10-42T or 10-40T XDR cassette exist?
Post by: lidation on March 04, 2025, 11:41:20 PM

I am building a new endurance/gravel bike with 1X drivetrain. I'd like to use XDR drive body for the rear hub.
I am looking for rear cassette: XDR compatible, 12spd, 10-40T or 10-42T.

I wasn't able to find any. there are 10-44T and 10-50T. But I really don't want that big of a chainring for weight and aesthetics.

Any thoughts? am I not looking hard enough or they just don't get made?

Spedao does make the 11 speed 10-42t, which is a decent cassette. Though they don't seem willing to make a 12 speed version.
