I need some help. Over the the last weekend I tinkered with my FD (F#cked up my front deraileur). It started when I swapped my rear cassette from 12/25 to 12/27 and installed a new chain. After the swap, I was getting more than usual chain rub on the FD. I made minor adjustments to the FD limit screws and all was good. On Monday I swapped back to the 12/25 cassette and had similar chain rub issues. I tried making similar adjustments to the limit screws as before. Minor adjustments quickly became major adjustmets and the whole FD was way out of whack. I did the whole drill on the Park site (loosened cable tension, reset inner and outer limit screws and readjusted tension). Everything was looking and shifting good without a load. As soon as I test rode the bike, the shift from the 39 to the 53 was terrible (maybe 10 revolutions before shiftin, if it would shift at all). I took the bike to a LBS on Tuesday and the mechanic did the same drill that I did, with the same results, maybe slightly better. I noticed this morning that if I "double pump" the FD shift lever, it shifts much faster. I have to move the shift lever like I normally would, then release it back and quickly move again to the shifting position with quite a bit of pressure. Any thoughts, tips, suggestions on what to look for or try? The chain is brand new and the mechanic at the LBS checked out FD position and chain ring condition, everything looked good. The drive train is all DA 10spd, and always shifted beautifully unitl now. I will probably take it the shop that built it for me, but they're 45 minutes away, so that's my last resort. Thanks for your help (I hope ).
