I think my understanding of how to change gears for climbing or decending is not right.
I have 21 speed bike 3 Cogs on the front and 7 on the back.
What is the proper setup for going uphill?
Currently I use my First gear in front and 4-5-6 in the back for flat to semi hilly roadways. On longer climbs over 1/4 a mile I am dropping my front gear into 2 and dropping my back gear into 1-2-3-4. I met up with a cylist who was on this route I made and he told me I might be going about my climbs the wrong way.
Could anyone explain to me or impart to me the common ideas/practices for proper gear shifting?
Thanks in advance.
