Hi Stefan
Tried to convert a cube hyde recently with a gates belt drive and a bbs o1 but it proved to be nightmare as the tension mounts under the bottom bracket fouled the top of the motor had to admit defeat
But have managed to convert a charge 29er single speed ok to alfine 8 chain drive ok can you post a picture of the bottom bracket, chain alignment is easy to adjust with spacers check out https://pirez.com.au/ very helpful for spacers and chain wheels
