I know these type of questions have been asked a million times but I’m having trouble finding an answer. I ride mostly street and have been looking to lower the RPMs for the 45 mph highways I go on. The only thing is that a lot of the slower speed roads have very steep hills and some of the highways have 20mph headwinds. Would a 14-45 sprocket set up hurt the performance way too much? And if not what’s the lowest I could go before being uncomfortable going up these hills. Thanks guys, sorry if this is a repeat.
