Hi - I've had my road bike (an '08 Specialized Roubaix that I bought used) for about a year and am doing my best to do my own maintenance and repairs. I just came across this site and it looks like there's a ton of good info here!
I'm having some trouble with my front derailleur (or maybe shifter?). I am pretty sure the derailleur is properly adjusted, but I could be wrong. I seem to have to put quite a bit of force on the lever to move to a higher gear (largest chainring), and when I do shift up the chain seems to grind a bit and have trouble catching.
When I shift down from the largest chainring, the shift lever (Shimano 105 STI) it feels like a lot of tension gets released and it will sometimes jump all the way down to the lowest gear. Other times it will shift down to the middle chain ring, but from here I will try to shift down again and it won't get to the lowest gear.
The chain, cassette, and middle chainring are all new (if that makes any difference).
As I write this, it really seems to scream "derailleur needs adjustment!" but I've tried tinkering with that plenty with no success. Could it possibly just be the tension in the front derailleur cable it too high?
Any help is VERY appreciated!
