re your stiff shifting, I recently experienced my shifter stiffening up considerably...tried all the ussual recomended fixes ie checking the cable liners etc, and couldnt fix it. I knew it was the cables cos i could swap wheels with my girlfriends bike and the shifting worked fine. I ended up changing my shifter cables from the rohloff ones to Shimano XTR cables and housings and the shifting now works very very well better than it ever was with the rohloff cables???!!!! Would be interested if anyone else has experience with alternative shifter cables to the rohloff ones.
