Sub compact chainset option for lower gearing.
Cycling Weekly (2017): The super compact chainset, otherwise known as a sub compact chainset is the latest gearing system to gain traction — especially in the world of gravel or all-road cycling. With even lower ratios than the original compact, which used a double 50/34 set-up, a super compact chainset runs 48/32 or even lower. From the likes of FSA, Rotor, Praxis, White Industries and now Shimano (GRX range of components).

I personally run 46 - 34 rings (110 BCD) up front and a 12-36 cassette (9 speed) out back. I switch to a 11-34 cassette when I feel the need for speed unencumbered.
