I have an older Lotus 3000R touring bike, I love this bike, but the problem I have is the it only has dual crank, 170mm , 52 and 42. So I am dying when I climb hills.
So I am thinking of upgrading to triple crank, but I found two that I am thinking of getting.
First one is 170mm, 52 , 42 and 30
Second one is 175mm, 53 , 40 and 30
I am not sure which one is a better choice. I would like to get some advice on pros and cons of the cranks I have described.
Thanks
