Overview
Fourth iteration of my magnetic paddles shifter design, this time with some distinctive modifications:
- Longer arm with more offset magnet position for better, stronger feel
- Lower total height
- Overall smaller package
- Switched to 15mm magnets only, can be stacked for even stronger response
- Same short throw as V2&3
- Customized to be used with thicker backplates and wider rim (mostly for my GT V2 backplate)
In the files you will find:
- Baseplate with cutouts for cable routing, two orientation of mounting hardware
- Short arms with and without indentation for paddle, longer arm for the wider rims so shifter can be nearer center of wheel
- Low profile and standard magnet holder if you want taller ones
- Experimental side plate to mount the shifter even lower, but some of it's body has to be inside the backplate
