I totally get where you are all coming from. I have been riding for weeks now, and everything seems to be going wrong. My bike is out of sync, gears and all are messing up, my Local Bike Shop is my least favorite place on earth these days, and now, my knee...it's still messed up. I wanted to just leave my bike on the side of the hill Sunday and walk the 7 miles that were left. I was so fed up that I offered to sell my bike to a friend (after it's tuned up and ready to ride). By Monday, my bike was gone, this friend was out riding my bike, and I was sitting at home...by 11:00 that night I was sad...I missed my bike.
So, I guess the moral of the story is, if your getting frustrated, and thinking of quitting, just give it a rest. Put the bike up and come back to it later. DOn't do anything harsh like quit or sell your bike...take a break...it'll come back to you.
As for me, my bike is most likely sold, but I am already looking for a new one, and can't wait to ride again...and it was like 2 days ago.
I know this makes me sound like a complete dumby...but there is a whole book about this bike and the size and all that. Turns out it was too big for me anyway, and selling it was a great thing.
