I dunno, there is also a good book by Allen & Coggan - bit of a study aid I guess. There are also some very good aids on bikemaxpower.com and google wattage group.

Nee Big H' date=' die beste plek om temperatuur te lees is in een van die liggaam se holte, die een wat op die saal sit, en die selfde een waar uit u gereeld praat![/quote'] Bruce dit is nie die tyd of plek om nou nasty te raak nie....... mens se u vir die landdros as jy verskyn vir parkeerkaartjies wat jy nie betaal het nie. Toe ek klein was, het my Afrikaans onderwyser my geleer dat ek moet die woord 'u' gebryk wanneer ek 'n mens wat ouer as ek adres. Iets omtrent 'n teken van respek.

Nee Big H, die beste plek om temperatuur te lees is in een van die liggaam se holte, die een wat op die saal sit, en die selfde een waar uit u gereeld praat!

Which is precisely what reputable power meters do! If I take a thermometer and measure the temperature at the top of a fridge and the bottom of the fridge and I find that the bottom is 1 degree colder than the top (which makes perfectly good sense). Is the thermometer faulty? Is the fridge a cr@p fridge? NO - it's just that cold air sinks so the bottom of the fridge will be colder than the top. Guys, these are simple concepts that are being ignored for the simple purpose of stirring ****.

Steady now big man - before you go throwing your usual wild assumptions around' date=' just consider that a Power Tap measures at the hub whereas an SRM measures at the crank - there will be a difference in reading due to drive train losses. This does not make either inaccurate - just reading from a different source [/quote'] Big H, why is it that when someone answers your question, you choose to ignore the answer completely? [NB. This is a rhetorical question, the answer is obvious to everyone] Sorry I could not get back..... we buried my Mother in Law today. Bruce the answer by Ursus Maximus is not an answer, it is a wild statement. It just confirms that this whole power training thing is a farce and something to keep the wundahboys apart from the normal cyclists. We live in an exact world. One kilometer is 1000m not 900m or 1100km it is defined by statute to be 1000m. Do you really want to try and convince me that powermeters is accurate. It seems to me to be beneficial to get the one that reads the highest so I can have more brag or wow!!!! appeal standing in the starting blocks of a race. No, if you get different reading from different manufacturers and empirical answers from other dink ekke hierrie hele ding is net 'n geldmaak foefie. Maybe I am a sceptic but please do not try to convince me 900m is equal to 1000m!!!!!!! Big H, read his answer again, then again, then again. Now, if you still don't understand what he is saying then let me explain. Power is lost due to friction in the chain - let's say 5 watts. Now, if I measure the power at the crank, like the SRM does, I will get a value, lets say 100watts. If I measure power at the hub (like the powertap does) at the same instant in time I will get 95watts. Why? Because 5 watts was consumed by friction, so 100 watts minus 5 watts equals 95 watts. There is nothing higgledy piggledy about this, it is just simple physics - something that I thought someone with your obvious intelligence could understand.

Hey, why keep the sensors on the bike? A pair of sidecutters with sort that problem out quick quick!

No it is 116km as measured on my Garmin. If you look at motionbased it sez bruce did 125km Bruce can confirm but I don't think they started and finished at the Dome. The route that I posted on MotionBased starts and ends in Fourways Gardens where I live. We met up with 101%, Ilidio and Mark at the corner of Northumberland and Hans Strijdom @ 5:30 - they came from the Dome side (Hillfox to be precise). We then followed the race route all the way until it joins Beyers Naude, at which point I turned left to miss the Lion Park road. The other guys went back to Hillfox via Hendrik Potgieter. So the route I posted is probably 80% of the route. So, 125km distance, 1500m ascent, 135bpm HR, and 280 watts Normalised power for 4 hours riding.

Some of the Meat Packers took Dr. Seuss for a nice easy recovery ride to check out the Dome2Dome route on Sunday morning. Curtesy of Garmin, check it out. http://trail.motionbased.com/trail/invitation/email/accept.mb?senderPk.pkValue=151260&unitSystemPkValue=1&episodePk.pkValue=3899193

Keep and eye on CyclingForums Power Training forum www.cyclingforums.com Some people at Eurobike have been posting there.

Thanks guys - yes, did read the thread. I was the one who posted Geoff The Aussies response to the whole thing Needless to say, am still going to have the party there

This is the subject of much debate! Seems like Saris use the Ant physical communications mechanism, but the message format is proprietary. So, either Saris must give Garmin their message format so Garmin can understand messages coming from the PT hub, or Saris must change their message format to be the same as the Garmin standard. Problem is that the PT hub would not be upgradeable from a firmware perspective - so, let's wait and see what happens.

Yeah, same argument applies if you are the coach and the client - which most people are.

Colonel: there is no dire need to train with a power meter - Eddy Merckx, Greg Lemond, Miguel Indurain, and every other top rider before the late nineties did pretty damn well without the use of a power meter. The benefit of a power meter stems from the fact that it is an accurate measure of how you are performing. Being able to measure something accurately means that you are able to measure changes and accurately know whether you are improving, going backwards, or just staying the same. So, training with a power meter improves the efficiency of your training, so you can either: 1. Spend less time training, and get the same results. 2. Spend the same amount of time training and improve your results. If you are perfectly happy with your results, and believe that there is no room for improvement, then hey, rather spend the money on something else. Or, if improvement of your results is not worth it to you, then the same argument applies. Most of us that ride are competitive and want to improve. What I can tell you is that I'll bet you spent a lot more on bike parts that would offer no where near the improvements you could achieve by training better. One thing is for sure, you will train harder with a power meter than without if you do it right.
