Just ride it for a while before changing anything. Looks like the stock saddle has been replaced, which is a good thing imo. Wheels might be replacements, but the stock ones are nothing special.

Heh. Looks like the computer is the same one I put on mine, a cateye astrale 8. Nice, simple computer.

Turns out mine is a 59cm, not a 60, there is no 60.

It is a comfortable bike, and even if a triple is not super fashionable, it's nice for hilly areas.
