… again! After getting all the components together, trying out various options for the rear derailleur and chain-ring, I have now completed all the work I am willing to do for now. I have ended up with the exact set-up that I started with – 10 speed, 11-34t with a 32 teeth chain-ring. In the end this looks like the best ratio for my riding. I will also be able to make use some of the components I’ve amassed for the 10 speed set up and switch them between bikes. This ability to use the same components, when I look at it logically, is clearly the better situation. To have two different lots of spares such as quick-links, chains and deraillueur spares is over-complicated and more expensive. The benefits of having slightly smoother shifting with either 11 or 12 speeds does not outweigh this simplicity.
