Following a TT Bike Fit I have been advised to change from a 170mm crank length to 160mm. I currently have a near immaculate Ultegra 6800 53-39T 170mm fitted and I am trying to identify the simplest and cheapest way of solving this.
I believe that I cannot simply swap out the crank arm only, as the right side is bonded on to the chain ring and that I therefore need to look at swapping the entire crankset? That being the case, I believe that a 160mm crankset is not made in the Ultegra range and that I therefore need to look up and down the range?
If I am correct, and I manage to source a Shimano FC-R7000 160mm, will I be able to swap this in? I believe that the bottom brackets are the same? Or is there a newer Shimano 160mm crankset that will fit?
Or....is there another brand compatible with the existing bottom bracket?
Thanks so much for taking the time to read and thanks, thanks, so much for any wisdom shared!
