Yes, we have discussed this before – just you don’t appear to have taken in the facts.
At 44mph, on a safe road, I’d always want to crank more – in a slightly tucked position, hands on the tops/elbows down/chin to the stem. 53/11 allows me to do this safely without the bike becoming unstable.
I get a “wider” range of gears because I have an extra cog, with 28 teeth. I used to just have a 25. Now I have all the same gears, including the 25, AND, a 28! So that is a “WIDER” range of gears. Can you see that?
Sticking with 53/39 makes the rations more “USEABLE” to my riding style, cadence and the type of roads I tend to ride on. I’ve explained this earlier: if I use a compact, I spend too much time flipping between chainrings.
Does this make sense to you now?
