Gearing change?
I moved from the flat ass prairies to any area where I am now having to learn how to ride hills.
I know almost nothing about gearing or derailleurs.
My 5 year old stock Giant Defy Advanced 3 has a Shimano Tiagra, 11-32, 10-Speed cassette and a Shimano Tiagra, 34/50 crankset.
I think that gives me about a 1.06 ratio in the lowest gear and I am finding that it is too high for me - in trying to keep my heart rate under 150, my speed is only around 7 km/hr and my cadence is in the low 40s
In addition, when going downhill, I find I can't keep up when I reach around 60 km/hr or so - i.e. I can't pedal fast enough to increase speed. I think that I am maxing out around 108 RPM.
I think that is a 4.55 ratio with my setup.
Is it feasible to change this up so I can have a higher ratio in the top end and lower in the bottom end?
I can't post a pic or link yet, but perhaps I could share Strava ride by DM if that would help.
