The Anteater

I have a roof rack and I do get concerned about stones and things that might get kicked up and hit the bike. I reckon I'd be willing to pay about R300 - R400 for a well designed cover, made from a reasonably heavy duty fabric.

Your statement there is wrong. Modulus refers to the stiffness of the material, it has very little relation to the strength of the material. As an example, almost every steel has a modulus ranging from about 19 000 tons/cm2 to 21 000 tons/cm2 while strength can range from about 30 tons/cm2 to 200 tons/cm2. It also look like that value of 65 tons/cm2 is a misprint. 65 tons/cm2 is not stiff at all - that's around the stiffness of rubber. I think it should be 65 000 tons/cm2.

All of this takes time and effort. If you're already pressed for time, but want to train to a specific goal, then a coach makes sense. Consider this scenario: Say it takes you two hours per month to plan, set up and adjust your program. Now consider that a coach may save you an hour of that. If you're a student on minimum wage, it perhaps doesn't make sense to get a coach. If you're a time-crunched professional charging R1000/hr+, then the time saving from a coach may well be worth it.

Can't you already leave feedback for buyers?

I wouldn't rule that out. 11-23 will make hills etc. feel harder (like you noted), but you may still be going a little bit quicker, simply through trying to maintain your normal cadence. It will also allow you to go a bit faster on the downhills. Another possible contributor to your faster ride might be that the wheel hubs and bearings on your friend's bike are better than yours, giving less friction. He could also have lower rolling resistance tires (or the pressures could be different to what you normally ride).

Now that this has been resolved, shouldn't this pic be removed? I'm not sure how comfortable I'd be with my address being stuck up somewhere for the whole internet to see.

Isn't this the case with almost all consumer electronics, though?

As soon as the link to the ad was posted, I had visions of the Hub vigilantes PMing and SMSing abuse at the kid.

Someone didn't read the Ts&Cs before posting their ad:

Excellent idea, I've joined up Is there any particular reason you created a FB group, rather than a page? I seem to recall reading somewhere that there's a limit to the number of people who can join a group and you need approval from an admin before your request to join is accepted.

Ask the person who will be shipping it to you. They normally have to declare the category on the customs export form for their country.

Agreed

In that instance it does make sense, but the uppercase in the original post (P=MV) makes it weird. Power = Molar mass x Volume?

I did. I'd say my statement still applies. Perhaps if he communicated the need for a very specific XT crank (year, size, diameter etc.), or brought the actual crank in, he could try returning it as unfit for purpose. It is unclear whether he did this or just said he needed one for an XT crank. Aside from the grey areas of unfit for purpose, I don't see how the CPA places any obligation on the supplier to accept the return. I am not a lawyer and my CPA knowledge is based on curiosity and a lot of reading. If it's inaccurate, please give me a specific reason why so I can learn further.
