I've got an old MTB hardtail GT Avalanche 1.0. Now it has SRAM X7 (3x10) crankset (but used in 1x10 setup with a nw chainring). This bike is my commuting and "road" bike.
With 36t chainring on the front I can't seem to ride as fast as I hopefully could with a larger one. So the question is: is it possible to install a road (or road-ish - like GRX mentioned in the title) double crankset and a derailleur on this bike? I want to leave flat handlebars in place in order not to make the geometry too strange.
Or, can I somehow use a double derailleur with a 3x crankset? Since I never use granny gear on this bike and don't like 3x mechs.
