I have a 2017 Kona Sutra touring bike. It has a 11-34 9 speed in the rear and 26/36/48 front chain ring. I live in BC Canada and plan on doing most of my riding here. A rider that tours a lot suggested I need lower gearing but didn't make any suggestions. So does anyone here have any ideas what might work for me. I want to do the Duffy lake road(89 km) as part of my first tour and it has some steep sections 13% very hot area of BC and I am 68 but in pretty good physical condition. Any help appreciated. Cheers Roscoe
