Ever since my aero road bike was stolen, I have been riding a cheap single speed bike on average 6 miles a day. The crankset was cheap and I recently switched to Sram Ominium 48t vs what the bike had 44t.
Overall the bike is faster but the chainring is on the larger side and i constantly have to standup if i am going up hill.
I feel like my lower back is getting stronger, but I am wondering what the physical advantages of a higher chainring on a single speed.
