Excellent resource, compiled cassette pitch / mech actuation / shifter cable pull data for 5 through 11 speeds, showing what mix and match combinations will work.
Interesting how we all like to moan about Campagnolo 11-speed having even smaller tolerances than 10-speed. But according the chart the sprocket pitch is only 0.1mm less than Shimano 10-speed, and the same sprocket thickness.
Therefore does this mean technically the same durability??
It has more durability because there is one more gear to spread the work around.
*This is a great compilation of a few links I had from various websites.
haha nice thought. Would be cool if it were true, imagine marketing would all ‘13 speed is 13x more durable!’
I was told there would be no maths but surely if this were the case:
- 10 to 11 is 10% longer wearing
- 11 to 12 is 9% longer wearing
- 12 to 13 is 8% longer wearing.
