Umm... No image?

Nice review. They are bitching sexy though...

Don't worry, found it.

But how do I get ST3, I'm still on 2.1 and the download section reckons that 3 is only being offered to selected customers

Hang on, L2 are you offering? How much?

That's what she said...

Atenolol is a beta blocking agent. It shouln't cause cramps. Is he on any lipid-lowering agents (cholesterol pills)? Those have been found to cause severe muscular cramping. Otherwise it is likely to be related to an electrolyte imbalance (calcium, magnesium, potassium etc). Get the doc to pull some bloods.

29er riders like to wear women's underwear.

Congratulations! This thread has been picked as a finalist in the category "Most Random and Pointless Poll Ever".

And I've decided to pick a side: 26er riders like to swap their bike saddles for dildos when nobody is watching.

At last! Some aggression. Now all we need are a few more 4 letter words, some exclamation marks and a sprinkling of personal insults.

Ummm... WTF?

Haha! Okay Slowbee, one Rock-Shandy coming up - delivered right to your rocking chair.

Ok, new pole: Who is the oldest, boringest dude on the hub? Slowbee: or this guy:

Ummm... Awkward.

Popcorn is cold, fight is boring! We need some aggression. I distinctly heard the 26er crowd insult the mothers of the 29er crowd

Wow, this is going to cause quite a furore. Popcorn in the microwave. Round 1: Fight!

Agreed - half the price of the equivalent Petzl and works like a charm. Go Ledlenser!

"approximate barometric and oxygen pressures at different altitudes, showing that at sea level, the barometric pressure is 760 mm Hg; at 10,000 feet, only 523 mm Hg; and at 50,000 feet, 87 mm Hg. This decrease in barometric pressure is the basic cause of all the hypoxia problems in high-altitude physiology because, as the barometric pressure decreases, the atmospheric oxygen partial pressure decreases proportionately, remaining at all times slightly less than 21 per cent of the total barometric pressure—Po2 at sea level about 159 mm Hg, but at 50,000 feet only 18 mm Hg." - TEXTBOOK OF MEDICAL PHYSIOLOGY, Guyton and Hall. ie. Oxygen partial pressures decrease with altitude.

When is it?

Hey cat-i. The benefits of altitude training are similar to EPO. Oxygen tension at altitude is lower than at sea level. Here in Jozi, we're probably breathing air which is around 19% oxygen. At sea level air is around 21% oxygen. So by training at altitude we are subjecting our bodies to extra pysiological stress due to the lower oxygen content of the air (ie the training is more difficult and we reach anaerobic threshold faster). The body adapts to this mild hypoxia in various ways. One way is to stimulate the kidneys to produce more natural erythropoeitin (EPO), thereby increasing red cell count and increasing the oxygen carrying capacity of the blood. BUT there are various checks and balances in place to ensure that the red cell count doesn't get high enough to cause our blood to turn to goo. It is a natural, adaptive physiological process. When we pump in artificial EPO these safety nets are bypassed and without careful monitoring blood can quickly turn to sludge.

Ummm... No, not quite. Oxygen doesn't cause blood to clot. The dissolved portion of oxygen remains the same. Oxygen carrying capacity is increased by an increase in red cell count and therefore haemoglobin concentration (secondary to bone marrow stimulation by EPO which is normally produced in the kidneys). The problem comes in because all those extra red cells increase the viscosity of the blood (ie the blood becomes like sludge). Pumping sludge around is not easy especially through small blood vessels, this compromises oxygen delivery to vital organs and tissues. You are correct in that this problem is exagerated at low heart rates (such as those found in elite cyclists at rest), this explains sudden death - generally at night (2010 Cape Epic anyone?).

Deep Heat is not aqueous cream.

The south is crap. Spaso is a stupid name.

Don't take a crap when hanging upside-down.
