So here's the story about my derailleur nice and quick:
I got my bike last July and pretty much since then, my shimano 105 set has been pretty bad, the gears at the back would never switch on the first click, and when they did on the second, the chain would jump a few cogs. Aside from that, my front gear would never switch into the big ring on the first click, id have to click twice and hold. The small ring was fine though.
I got my back gears fixed about 2 weeks ago and they worked phenomenally for about a week, then my chain fell off. I then brought my bike into a shop to a man who is basically a professional in cycling, no tour de France type stuff, but pro in about everything else and so I thought he'd do great job. My firs ride out with the bike after he fixed it completely, everything worked perfect and smooth. But my chain feel of again...
I've realized just yesterday that when I gear into the big ring at the front, it throws my chain over and falls off. So no more big ring for me, at least for now.
Anyway, I was just wondering what was causing this all to happen!? Could it be my gears, shimano 105 set,my bike in general, or just me? I am afraid to try and move the front derailleur over because I'm a huge newb at that stuff and just end up braking my bike when I even get near anything mechanical on it. If you were able to get this far, any feedback is appreciated, thanks!
