comment Why does the glue in a puncture repair kit dry up so quickly?
@Vorac, yes, those are "good enough" to get you going again in a bind, but in my experience they're never as good as traditional patches.

comment What sort of bicycle helmet gives me better speed?
There are MANY contributing factors in a time trial (which is what you're talking about) of which the helmet is but one. No one factor completely dominates the other. If you're going to use a time trial helmet, then you might as well go with a skinsuit, shoe-covers, time trial bike, disk wheels, glasses, someone to block traffic for you at each intersection, a ramp in your driveway, and some time in a windtunnel to tune your form. Moreover, 34 kmh with all the trappings will scream "fred".

comment Speed improvement from hybrid bike to road bike over 9km at 30 kmph?
Why should "all other things be equal"? If you just like the Cannondale road bike, that is reason enough but if you're strictly trying to quantify a meager ROI ($1000 for 30 seconds on a 10Km trip), that will be a disappointment. Just pedal faster. 30Kmh is not hard to achieve on a flat dedicated bike path with almost any bike.

comment Is a tri frame suitable for track racing?
Yes, the first thing that will disqualify even a properly "converted" tri-bike is the drop-outs. You can't participate in an event if your rear-dropouts are not rear-facing.(like this framebuilding.com/NEWPARTSPAGES/NEWIMAGES/y5.jpg )

comment Are there any scientific studies proving the benefits of clipless pedal systems?
@headeronly, yes, that makes sense. Of course, the reason you HAVE TO do that is simply because you are riding a gear that is too high for the hill, so downshift, oh- you can't you're on a track bike, that's when your buddy will drop you while riding his ten speed. :-)

@headeronly, pulling-up with significant force on pedals is certainly done for brief accelerations. Doing it longer than very briefly is unheard of imho. The generally regarded best form is to pull up just enough that there is zero pressure between your foot and the pedal on the upstroke-- that is truly "pedaling in circles" and it can be done indefinitely.

comment What will I need to consider when modernizing a pre-1990s steel frame?
@7thGalaxy, OK, as long as you're doing it right. :-) It must be a pretty awesome frame to go through all that trouble. Good luck.

comment What will I need to consider when modernizing a pre-1990s steel frame?
It really is the rear axle adjustment that is a P.I.T.A. to "do it right". It doesn't just need spreading with a 2x4, it needs to be re-aligned so each side is parallel (sheldonbrown.com/forkend-alignment.html), risky and definitely not fun. What's the point of a nice vintage frame if the wheel insertion/removal is ghetto? :-)

comment What will I need to consider when modernizing a pre-1990s steel frame?
It is going to be a lot of work, especially if you fit a modern hub in the back (you'll have to deform the rear triangle to do it right). You might want to reconsider and keep the downtube shifters, upgrade the components to the top-of-the-line for that era. Downtube shifters, when adjusted properly, are nice and responsive. The only thing I would get rid of are those unsightly brake cables looping high into the air-- replace those with aero brake levers (early-80's tech).

comment Why top touring bikes have no suspension forks?
Suspension is really not necessary for touring. It really is only useful in severe single track terrain. If you have hand/wrist issues, first check the fit of the bike (stem height/extension, top-tube length, seat-height) and your form. Things like gloves, handlebar tape choice and a slightly lower pressure in your front tire (or wider tire) will make a lot of difference and have less drawbacks than a suspension fork.

comment Lots of broken spokes on one bike, with different wheels
Another thing to check is the trueness of the wheel and the tension of the spokes. Are they all uniformly under the proper tension? Are some so loose that you could, with fingers only, turn the spoke nipples enough to loosen them? The last step in wheelbuilding is a strain-relief step where you squeeze pairs of spokes with your hand-- if any are loose again after that, they need to be re-adjusted.

comment Techniques for safely leaving a bike for 1-2 minutes in a safe-ish place
If you live in a place where 3 of your friends have had their bikes swiped by leaving them unlocked for a short time, I would suggest that you just LOCK the bike. The only other alternative is to simply accept that there's a risk it will be ripped off.

comment Repeat Punctures
Yes, I would add that a careful inspection of the outside of the tire where you pinch the outside tire to open up all the visible nicks often helps to find embedded shards of glass or metal. In a situation where you're on a long ride, not finding the root cause of a flat is a recipe for misery.

comment Are there any scientific studies proving the benefits of clipless pedal systems?
@AdamRobertson, I also find this "consensus" to be silly. If there truly were no advantages to clipless, you would have see some riders use platforms in races-- but I have NEVER seen that. Clipless pedals are universal in everything from pro races down to CAT-5 office park criteriums. There are some track riders that use straps, but even there, clipless is the vast majority. Perhaps there is no "scientific evidence" simply because it would be too boring to explore the obvious?
