GorillaBoy Posted June 22, 2021 Share Hi everyone. I am in the process of purchasing a Rotor 3D+ Power Crank with a 130BCD. The chainrings are almost done, but I was gifted 110BCD Qrings. I would like to know if it is possible to change the Power Cranks spider out to a 110 BCD? It looks like the spider can be removed, but I am not sure. Hopefully someone has had experience with this. I have a Vision Trimax Carbon Crank which has 5 Bolt 130BCD chainrings on like the rotor. Will they work if push comes to shove? Link to comment Share on other sites More sharing options...
Thomo Posted June 22, 2021 Share Generally Rotor spiders are kept in place with a lockring. (pretty sure it's the same for this crank) Should be possible to change albeit perhaps needing a proprietary tool. DieselnDust 1 Link to comment Share on other sites More sharing options...
