revised Difference between “Track Frame set” and a “TimeTrial/Triathalon frame set”
changed erroneous "brake" (meaning most probably "break") to more understandable "disconnect", plus other understandability fixes

comment Are slick tires worth it for commuting?
@amcnabb - You are exactly right, it does not even make sense to make a graph for am unspecified, non-zero, but positive grade, for the purpose of comparing rolling resistance to air resistance. Plus the source of the graph is Schwalbe, and it's obviously in the interest of the tire manufacturer to overplay the relative importance of rolling resistance.

comment Are slick tires worth it for commuting?
Now we are splitting hairs, but what do you exactly mean by commuter bike speeds? I see two different commuting approaches possible - either you absolutely avoid getting sweaty, and so you indeed ride at less than about 100 watts, or you don't, in which case you ride as fast as you can (probably about 160-200W for an untrained male in OK shape). In the former case it's true that rolling resistance is of relatively bigger importance. But as the OP cares about speed, I suspect we are rather talking about the latter approach.

comment Why are tubeless tyres popular in mountain biking?
Against pinch flats (snakebites) I can understand why - but can you explain why the tubeless tires are especially good against thorns? I don't get it.

comment iPhone app to follow/navigate an imported .gpx
While MotionX is not exactly what I was asking for, I have downloaded it and used it for over a year and I can confirm that it's an excellent app for cyclists (or anyone who navigates in a terrain). What's especially compelling about it is that it can download maps to local storage, in a dead easy way, so it's extremely useful during foreign trips, when downloading maps on-the-fly via 3G connection can be prohibitively expensive.

comment What is the “preload” setting on the front fork suspension?
Typically so, but just to be sure I would consult the manual for your fork to see if it adheres to the convention.

comment Is my interval training routine effective for mountain bike training?
Yes, as long as, again, you don't mix it in with weight training. The idea is that if you want a session of higher intensity training, such as threshold, intervals, or sprints, to be effective, you should train hard. You should feel like you should be carried off the bike at the end of the session. Then rest at least two days before attempting another hard session.

comment What are the advantages and disadvantages of riding a smaller Mountain Bike frame?
@Jahaziel The internal forces in the frame will be smaller, but the external forces exerted by the necessarily longer stem and seatpost will more than make up for it, because proportionally more leverage will be added externally than removed internally.

revised What kind of bicycles do they ride in the Tour de France?
Corrected after comments from Robert Koritnik - as of 2011 top bikes no longer have aluminum frames

comment What kind of bicycles do they ride in the Tour de France?
@Robert Korytnik: You're right, I was projecting from maybe 2007, when I remember some sprinters still used alu frames for their better stiffness. Edited.
