I recently bought a Trek 7300 after an agonizing search. I test rode many bikes.
Unfortunately I feel the bike I ended up with is not right. The shifter on is on the grip and I constantly turn it when I am not meaning to especially while going uphill. Is it possible for the shifters to be changed to a more user friendly type. It seems like I only have a few inches on the grips before the shifter.

I feel like the bike is heavier and cannot get up to the speed I was riding on my old bike, is it the weight or tires. I had a older Raleigh that was a also a hybrid. Could it be the different tires or am I just crazy like DH claims?
