Just recently got my first real bike. I purchased a Giant Rock 5000 530mm frame size (non-disc brake model) and aside from a Cat's Eye light, it is exactly as it came out of the box.

So far I absolutely love the bike, and had my first experience with truing a wheel (back tire was grazing one of the V brake pads in a certain spot) yesterday after giving it it's first cleaning.

The bike is great and since I live halfway between Yokohama and Tokyo, there's naturally more rode riding going on than non-road riding.

The road riding is usually 40km round trip, on pretty hilly terrain with some bad roads/sidewalks. (Anyone who has ridden in Japan probably knows exactly what kind of terrain I am talking about.) The non-road riding is usually long the river bed of a major river, where it's usually a dirt road, foot-beaten path or occasionally riding through heavy grass where there's no real path. These trips have been about 30km at their longest. I would like to eventually ride longer both on and off road, but most of the traveling is with my fiancée who doesn't have the stamina or speed (thin, non-athletic Japanese woman) to want to ride more than 30 or 40km in a day.

So far I've purchased CRC w/ Teflon Spray, some cleaning spray, a large pump for home and a small pump to bring with me on rides, as well as a highly reflective vest.

The first question is, what non-bike items should I be considering for purchase based on my riding? Is it better to bring a spare tube, or a tire puncture repair kit? Anyone inside of Japan have any specific insights for me?

The second question, which I am very interested in hearing a range of opinions on, is what components on my bike seem to be the least desirable? I love the fact that the bike is light, the front suspension is great, and the brakes work fine. I'm sure disc brakes, rear suspension and a variety of other innovations have their strengths…but for the riding I'm doing, what components would you be thinking about changing, and why?

Below are the semi-translated specs for the bike.
(One of the problems here is that I'm not a native Japanese speaker, the other is that this is my first real bike, and I don't have the proper bike understanding and/or English vocabulary to translate it confidently, so there's some original Japanese left in there)

Question # 1I would say both. First line of defense is a tube. Allways easier to repair tubes while sitting at home on the couch. But if the second tube were to get punctured it would not be a bad idea to be able to make the repair.Question # 2 you allready answered. Get out and ride it. Replace what breaks or wears out. By then you will have an idea if something was not living up to your expectations. :D
