yesterday i tackled a 20 deg, more or less, climb for about 45mins.. Actually this must be the steepest road I climbed..
Although I enjoyed it a lot, the pain was almost unbearable..
My easiest gears are 42T-23T. With this combo, i was doing 10-12kmh @ about 45rpm cadence.. In my fitness level it is impossible for me to spin with those gears at 20deg inclines..
What can I do about this?
I can replace my cogs, but I still have the derailuer limit of 27T right? I have a Shimano 105 rear der. and currently have a 12-23 cassette.
If I replace my small ring to a 38T, would it make much difference?
Thanks.
Now THAT! is a hill where you need a triple.
