-Why should i upgrade my jockey wheel to 12T when my stock running 11T for Both?
- Only 1 teeth more than stock pulley? Might as well to go for 13T,,isnt it?
When it comes to ratio, its not just the number of teeth but THE TOTAL DIAMETER is actually the one that manipulating any gear's character.
This 12T is BIGGER than most aftermarket 13T. See photos. Therefore the character would be something better than 13T pulleys.
Some SRAM MTB ALSO CAN USE THEM. Not sure about Shimano Campy RD though. Reccomend to install 1 pair to ensure the width of the cage arms are balance and parallel.
