Are there any benefits to biking in a higher gear. I do not mean as in when I am going downhill, I just mean will it help me get better. I have an 8 speed bike with 24 gears. If I am on flat ground, what is a good gear to be in? If you have an answer to this part, please put the gears in an ordered pair. Like this: (3,8). And if you have a specific reason, please do tell. I am new to this, so if you think I need to know anything else, please do tell me. Thanks for all of the help.
