Bicycles/Maintenance and Repair/Gear-changing Dimensions - Wikibooks, open books for an open world

Excellent resource, compiled cassette pitch / mech actuation / shifter cable pull data for 5 through 11 speeds, showing what mix and match combinations will work.

Great resource.

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. :stuck_out_tongue:

*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.

Some links of mine related to mix n match of the above systems…
