First time commuting for a while this morning.... I forgot how HUNGRY I get during the day Great to be back commuting though. Best way to start a day.

Yeah.... you are assuming they actually trying to USE the indicator

It does a little. Still in my top 5 movies of all time, and I watch it about once a year.

If a CFO slips up in his professional capacity he goes to jail for fraud and never works with money again. If a doctor slips up and makes a negligent mistake they get sued and will most likely lose their medical licence. Engineer, same. A "mistake" in this context is professional negligence at best, fraud at worst. I same should apply to cycling, life time ban. 2 years is a joke, and reducing sentences is even more of a joke. Nothing will change if there are no consequences.

Unfortunately not a true story

I was seriously considering them, until I saw the guy in front of me at barberton pulling leaves off the bushes to help him grip after the river crossings... case closed for me.

I think you mixing up a few concepts. Force, power and energy are all different. Mechanical leverage is used often, and its a trade off. For example, with a lever you can lift a heavier object. That doesn't mean you suddenly applying more energy. Energy is the same, because you are moving the heavier object a smaller distance (Ep = mxgxh, mass increases but h decrease, energy is conserved) Other examples of leverage are pulley systems, hydraulics, gearing on a bicycle. So in this case, 29er brake force must be higher because the disk is travelling less of a distance (wheel rotation is slower at the same bicycle speed). Energy is still conserved.

yes... yes, you are. But you are also right

The same force will be required on the tyre that is in contact with the ground to bring two equal bodies to rest... yes. But the way that force is transferred to the brake it will not be the same. Its mechanical leverage.

Close enough. But you taking a long way around to get to: M = Fxd As someone else said, think about it as a lever.

Er... I did

Just from a science point of view.. Its about the application of force. Rotor pad apllies a force at a certain distance away from the hub. This creates a stopping moment (or torque if you would prefer) applied at the hub. The equation is M = Fxd. (d is the rotor radius) That same moment is then applied to the stopping power of the bike, using the same formula, except now the stopping force F is applied to the ground and the distance d is the radius of the wheel. if the rotor size and braking force are the same (ie one finger same pressure), then the increase in wheel size will decrease the stopping force

I can't believe people waste coffee like this. Makes me want to vom in my mouth.

+2 on the SLR carbon. 119g and ridden on hardtail (including j2c) and dual sus (including many stage races and trans baviaans) mtb for years. Its a hard saddle, but I find it very comfy. It might not be fore everyone because of its hardness. I got mine for R1100 off CRC a few years ago. With specials and shopping around, I think you can still get it for under R1500.

You have said it, but not spelt it out properly. You need to find what value you will have to the sponsor and sell that to them. That means on the bike and off the bike. On the bike = podiums at events with good coverage. Can you offer anything that would promote a brand off the bike? Think social media, workshops, offering training courses, writing articles... etc. Basically you have to turn yourself into a brand that will support their brand. And then sell it. Here's an article that might help (there's a part 2 somewhere as well): http://home.trainingpeaks.com/blog/article/how-to-get-sponsored-part-1

Sho. RIP. Can't imagine how he felt for his whole life. Think I will get hold of that book.

I don't understand why you are trying to work this out. If you start going up a hill, generally your speed will decrease and your watts will remain constant. Your watts might increase, but only as much as you want them to (Ie if you push harder). In a long endurance race (eg iron man), you ideally would want to keep a consistent wattage the whole way through, so you would ride uphill slower. To know the same wattage for an increase in gradient seems like the least useful measure to know, and as some have said, I think you are over thinking it. Unless there is something I am not understanding.

Hey. What type of riding? When do you ride? What pace? There's a what's app group of people in the Randburg/Welties/Northcliff area I can ask if you want to join. Nothing formal, just to let people know who's doing what.

I agree. Most of it is rubbish that wasn't in the book. They tried to make it too epic and lost the plot a bit, IMO. Both movies, I walked out feeling like they were fleecing me. I guess I'm just a sucker, because I will have to go see the last one too.

Saw this as a play with Nick Borain (sp?) and loved it.

Nobby nic is VERY grippy but has high rolling resistance. Unless you are riding in very muddy conditions constantly I would save it for a front tyre, and even then, only if the grip is needed. Mine also wore down quite fast, and at the price decided not to go back. I also mainly ride XCM, so the high rolling resistance put me off.

Is that the teenage, drugs, aids one? Was great back when I was younger. I think all teenagers should watch it.

Wow some great movies on here. I am quite a fan of the classics like Full metal jacket and Dr Strangelove (watched it again last week). I must say, Grand Budapest Hotel had some entertaining parts, but as a whole I thought it was a bit dull. I thought lego movie was spot on. The humour and storyline was a perfect mix of stupid with a bit of a clever undertone. And Will Ferrel is awesome. I don't think you could expect more from a lego movie.

Employee: I'm going to see my GT Boss: Don't you mean your GP Employee: Uh, yeah... That's what I said

I agree. I think it depends what level of state intervention you are happy with. For example I think the intervention of the NCA is a good thing to protect mostly uneducated and desperate people from debt traps. This however, is a bit extreme. If you are willing to report these people to the consumer protection body, you have too much time on you hands. Do you really want to become such a nanny state?
