Wheelbuilder Aero Disc covers
Genuine Innovations Air chuck + Topeak valve extender
I need to use a valve extender because I have deep rim wheels and it seems silly to have all this supposed aerodynamic benefit only to wreck it by using inner tubes with long sticking-out valves. What sets this valve extender apart from all the others I have seen and tried, is that it very cleverly allows you to close the (concealed) tyre valve, thus avoiding air (or CO2) leaking out.

this using its special shooting modes. Slow motion video (or, what is as far as I am concerned confusingly called "high speed video") can help you iron-out your running, biking and swimming technique no end. The camera never lies: you can see ever little unconscious movement, as well as the conscious ones. It doesn't tell you how to fix your technique but it helps you measure whether you are on the right track. And you can make your own "Chariots of Fire" style videos at long last.

The tool is a beautiful thing. If you like well engineered marvels like mechanical watches, knives, fountain pens, etc., then the reassuring weight of this torque wrench in the palm of your hand banishes images like the aforementioned pile up of human flesh and carbon from your mind. It is a joy to use, but I only have so many bolts to tighten - now I have to wait until I have to reassemble my bike before I need to use it again - damn! Unlike most other torque wrenches, once you hit the dialed-in torque, it doesn't slip all the way round - it simply makes a loud click and gives about 3 degrees of free movement. This means, of course, that if you want to, you can continue to tighten until something gives but then, this would make you a moron. The reason for this is that they have been able to design it so that the bolt you are tightening is at right angles to the wrench and so there is no need for an extra piece to give you the leverage you need.
You should be warned that this kind of quality does not come cheap but, compared to even the insurance you'd probably take out on shipping your bike, it isn't as much of a luxury item as it might at first seem.

I suggested to the guys who came up with this idea that they should make something similar to cover the swing arm of the front derailleur which always gets clogged up with mud and stops shifting properly. They claimed that they had already thought of it but had abandoned the idea. I'm hoping that they were lying because my gears get jammed every single time I ride in and I often have to struggle up a steep hill mashing the big chain ring.
