Mr alfeng, good guess, i got the front derailer to work but it needs to be about a 1/2 inch longer. When the chain is in the first gear [the 30 tooth] the chain rubs on the bottom roller only when i choose 7,8,9 gear on the rear wheel. Otherwise the derailer works great. back on my progress got to put a few miles on and had to cut down the shim and collar on the left side. i'm pretty close to getting it fitting correctly but man what a difference this is. the bike feels like it should have been made this way, so before i push it more i need to finish the fitting but this was definetly worth this to me [the time and effort] i cant wait to push harder and make the smile bigger. rocky j
