hello,
this morning i tried the new system, wich bike upsidown was working perfectly...as soon as i start pedaling the chain was skipping..i could go forward but was like it was skipping some bits..damn!.. at this time i was still using my rear derailleur , and i could also change the front gears perfectly, only problem is the skipping chain!Is it possible that is the chain not compatible or the front chainring with the back one? or what could it be? i use to have a threaded freeweel and instead my single speed is a cassette. is possible that is that? is there a solution for it?

...sadness.....
