alright boys i am considering to lower my gear ratio . i used to live in a pretty flat area so i went 4819 for chill commuting but i recently moved to a reaaally hilly area and i ' d like to lower my ratio just slightly . would you rather go 4820 cheaper since i only have to replace the cog but higher decrease or 4719 more expensive but lesser decrease . what do you think ? thanks for any recommendation ! <| sep |> Made friends with my cousininlaw ' s fianc last thanksgiving for exactly this reason . We were the only two but I ' ll tell you it was a huge relief . <| sep |> Took me a while . Then I realised people have pockets on the back and it clicked . <| sep |> Rainbow Alma .
