Well I installed a RF Evolve XC X-type crankset on on my '05 Prophet 600, it's been on the bike for a couple of months and has been screwed up from the get go. The problem is I cannot get the front dérailleur adjusted properly so that it does not rub the chain with this crankset. I've tried just about everything and no matter how I tune the limit screws on the FD it always rubs the chain in certain gear combos. I can get the FD to not rub the chain in the smallest chainring, but then in rubs is the middle and large chain rings and vice versa. Furthermore I have to use all three chain line spacers with the crankset otherwise I get terrible side to side and vertical play in the crankset, your only supposed to use a max of two. One more thing, no matter how I adjust the chainline spacers it makes no difference in helping the dérailleur not to rub the chain. I do know how to work on the FD, and I just don't understand why I cant get this set up properly, I'm seriously considering re-installing the stock Truvativ blaze crankset that came with the bike as it worked properly. Please help if you can.
