I am new to road bikes and tested some new bikes yesterday and had some questions regarding what I noticed regarding shifting (on 105/Tiagra) yesterday.
Shifting up either rear or front chainwheels were relatively loud and rough. Shifting down in the rear was smooth but shifting down in the front was problematic and rough. On the front, I had to some times press the lever twice to make it shift to a smaller wheel.
Q1) Do these drivetrains smooth out after a few rides?
Q2) Is it my inexperience with using the modern Shimano shifters that's causing some of the problems?
Q3) I also noticed that the drivetrain was much more susceptible to cross chaining than my mt. bike ever has. On my mt. bike, I only sense cross chaining on the smallest or largest chainwheels. It seemed on the 105s that I had it much more often. Is this something that decreases with usage? Or do I need to be much more careful?
