  1. Well, that's sort of what I meant (just poorly stated) - that the two were not the same. My comment was in light of the comment along the lines of that restricting oneself to power based thresholds was not as effective as using a HRM. Hence my comment that I'd like to see longer intervals where the time actually spent in the target zones would make the tests more comparable.
  2. I'd heard about this study on a club ride a couple of weeks ago and the perception was also that "using a HRM was more effective". Glad that I've read the posting and the thread generally. My take out is that trying to compare two the systems like this does not prove that one system is better than the other but that for this specific test using a HRM is better because of very specific characteristics of HR training. I'd be very interested in seeing a similar test for threshold stuff. Good stuff!
  3. Lazy sod ... Read this then Clincher rims Most bicycle rims are clincher rims for use with clincher tires (also known as wired-ons or wire-ons), which have a separate airtight inner tube enclosed by the rim and the tire. Modern clincher rims have hook-shaped edges to hold the bead of the tire in place, allowing high (8?10 bar, 120?150 psi) air pressure. If the inner part of the rim where the inner tube fits has spoke holes, they must be covered by a rim tape, usually rubber, cloth, or tough plastic, to protect the inner tube. An advantage of this system is that the inner tube can be easily accessed in the case of a leak to be patched or replaced. [edit] Tubular or sew-up rims Some rims are designed for tubular or sew-up tires (also known as singles in Australia), also known as tubulars or tubs, in which the tire is sewn into a tubular shape and then attached to the rim with an adhesive. A tubular tire may or may not have a separate innertube inside. Tubular tires requires more labour to repair a puncture than clincher tires. The tire must be removed from the rim, opened up, patched, sewn back up, then finally glued back to the rim. Clinchers have largely replaced tubulars for amateur racing, but tubulars are still commonly used for indoor track racing (where the closed track makes punctures from debris less commonplace), professional road racing, and road time trials. Advantages of this system include a decreased chance of pinch flats, it can be made to operate in a wider range of tire pressures (from 25 to 200 psi). Furthermore, when a tubular goes flat at high speed there is a safety margin because it will not roll off the rim if it is properly glued on. Taken as a whole the total weight of a tubular rim and tire is usually lighter than its clincher equivalent. However, for all non-racing purposes the lightness advantage is somewhat offset by the need to carry at least one entire spare tubular tire (only a patch kit or inner tube are needed if using clincher tires) Tubulars are most popular for bicycle road racing applications and it is argued that they provide a better road feel and are safer than clinchers in the case of a puncture while the bicycle is traveling at high speeds, also for track racing where punctures are rare.
  4. 12 year old piece of junk - toss it!!
  5. What is helicopter tape? Post a pic.
  6. I can't judge on anything other than I have seen aired in public and what Chunky himself has said and posted here and on other cycling forums. I am not judging the person, I am judging what he apparently represents. And he really may be a nice guy so I'd just like to see him state that he does not (no longer??) advocate the use of illegal ped's. Until he does that it would not be right to have him in any influential position within any sport.
  7. vermark are half the price of Assos - I think in the order of about R600-R800 too. I swear by them.

  9. Precisely ....... He did what he did and now its time to move on!! Gibbs admitted to throwing matches, which to me is far more disgraceful, and yet he is still allowed to grace the oval!! Give the man a break!!!It's one thing giving someone a break when they have accepted that what they did was wrong - morally and legally and then to follow that up with a stance which reflects that. Unfortunately I have never seen a single posting from Chunky that would lead me to believe that any of this is the case. It's another thing giving someone a break who steadfastly appears to support illegal drug abuse. And I am not getting into the wider doping debate - it's all been said.
  10. But flaming me won't have the same bragging value that taking a TV personality on affords. "Hey, babe you know that Yellow saddle dude on TV.?" "No hun, which one" " Man.. you know the dude on Supercyclng sometimes." "..... mmmm ...... Sweetie Pie ..... maybe ...." "Ag anyway ... I sorted him out today. Everyone can tell that he isn't a real cyclist - he just doesn't get it. Everyone knows that ceramic wheel bearings make a huge difference and tubbies are faster than clinchers. No real cyclists will carry a spare tube during a race anyway. It just isn't cool and besides they weigh 30g. Also he doesn't shave his legs ... what does he know?" "Really hun?? A real TV personality... does he know Andrew McClean?? You are soooo clever my cutie pie. I'm really proud of you."
  11. It's the gadget that you will finally end up with in 18 months or so!
  12. Exactly, .... and the minimal difference in weight does not factor in the real world.
  13. I guess JB is pissed off with people putting words in his mouth. Don't blame him - every time he comments there are 4 or 5 23yr old rocket scientists (engineering students) that flame him. ps and 1 not so young tar mechanic Windbreaker2008-03-26 10:24:49
  14. Hey WH, I am persistent but I gave up on the old polar. I actually ended up making little teflon bracket things so that I could be sure that the sensor was EXACTLY in the right place and still I had differences between the different gear combinations. The one thing that I did learn was that the vertical distance between the sensor and chain is not nearly as important as making sure that horizontal position (front, rear, left & right) is as close as you can get it. Ignore the extreme "cross chain" gear combo's (assuming that you won't use these) and get the pickup section of the sensor under the part of the chain that moves laterally the least. For the vertical position get the sensor close to the chain without it touching in the small ring combo's. The magnet will suck the chain onto the sensor while there is no tension on it but it musn't touch while there is tension. Unfortunately even with weeks of fussing around I could still never get it good enough for my liking. Black Hill was my testing ground. The gradient from the Glencairn side allows you to use a bunch of different gears and the gradient is quite even. Good luck. ps. I saw an advert on gumtree for a PT SL with wheels for R5k.

  15. I owned the old type and now also one of the new ones for my tandem. Would buy a used PT instead for a single. In fact i did - a while back. Ewep, pick a slight steady gradient hill and keeping your speed constant go through the different gear combinations - about . Bet that you see inconsistency to some degree.
  16. get a used pt instead. they sell on here quite regularly.
  17. I was also very surprised and quite disappointed b the poor turnout from the younger cyclists out there. 38-32 was very close and I still don't think that the PPA Exco really has a grasp that their membership comprises more than just people interested in recreational cycling. Some do no doubt but they need to start focusing on all aspects of cycling and either take this responsibility on themselves or they need to make room for WPCA to grow and provide some funding for it to. One question. If all the WP clubs are currently affiliated to the WPCA and WPCA and PPA merge does that mean that all clubs would become affiliated to the PPA?? Bit of a dilemma that one.
  18. Tighten them just enough so that they grip the skewer without any play - make sure that you tighten the lock nut to prevent the thing coming loose while you are on it. I am a real convert. in the 3 months leading up to the Argus I managed about 4- 6 hours per week (including warm up and cool down time) on the trainer and one weekend ride (two when I was really lucky). I am as fit as I was last year when I was doing about 14 hrs per week on the road. Bike has suffered no ill effects.
