Right well as most of you know i have a mad phase 1.2, and for some reason the chain keeps jamming up on the front cog when i peddle and is really dangerous. So, what i was thinking was, if i take off all the shifter and cables and shorten my chain so the derailuer is practically upright, this would help. Also is it possible to have the derailuer off completely as it annoying, if i can get me chain the exact right length. Heres a pic of my deraileur and gearing on back end. Your comments would be appreciated. Thanks P.S I am getting the single speeded done properly when i get paid.
