Well I guess taking me as an example I use an 11/28 cassette with compact chainrings.
I use a Kurt Kinetic road machine with a stages.
When taking the cassette ratios in to account it is only the final five cogs that are single tooth jumps from 15-11. The rest are two tooth jumps. I believe I am either going from the 19-17 or 17-15 in the final rounds.
It doesn’t sound like much but when you are already pinned the decision to either raise leg speed to 100+ rpm or shift is a pretty tricky one. I normally shift and and it takes me back to sub 90 rpm and I can’t see myself getting past the 400w step on the test.
