Super-niche #biketooter question. I find the gearing on my gravel bike to be a little high with an 11 speed 11-34 tooth cassette in the back. I never use the 11 and would love one more higher gear. Is there something available in 11 speeds that’s, say, a 12-38 or something? Everything I find is 12 speed. Thx.

edit: yes, I could do a smaller chainring, but I need to replace my cassette anyway, so I’m just considering options.
