  • PowerTap Training Tips From Around The World

    I was wondering if anyone else has had a similar problem with their Powertap powermeter. If you are capable of generating many watts at your threshold power, you are likely to be a successful rider. I thought the Garmin 705 would be the ticket, but of course, it isn't compatible with the PowertapSL 2 competitivecyclist. Any other ideas to try would be much appreciated. These analyzes can be time consuming, but it is here you really get the value for your money. It might sound controversial, but road cycling is not as scientific as many cycling coaches would like to think. Light weight PowerTap SL is a lighter version of the original PowerTap Thanks for any help. They require a coded strap, such as the Cycleops and Garmin. Their training principles probably include more LSD training (Long Slow Distance Training as used by runners) than my training programs advise and I have to admit that these riders become extremely strong (or at least some of them do).8kg). I wasn't aware that Powertap heart rate signals are encoded. If you hit the lap and both buttons for interval on the PT, you can match stuff up pretty good. However, there are other ways to train, which will boost your aerobic engine. Maybe that somehow skewed the coded 'signature' expected by the Powertap monitor. You need to put in consistent work over several years to build the necessary endurance to reach your full potential as an endurance athlete. PowerTap and SRM only use uncoded. The coded PT straps are an improvement, but from time to time they wouldn't read for me, with no apparent reason. AFAIK there is no hardware reason why the two couldn't talk to each other. They require a coded strap, such as the Cycleops and Garmin. I guess I'm supposed to buy a $650 computer and hope that it will eventually support my $1k+ power meter." A bit off topic, but are there any non-Polar head units that work with coded Polar straps? I find the Wearlink strap way more comfortable than any plastic straps, but it seems that it only works with Polar stuff. You hold down the Mode button and you will switch between total time and interval time (assuming you are showing the Time segment on the bottom line).I contacted someone at Saris (parent company for CycleOps), and was told that they were working with Garmin on something, but did not have details or a time line. If you use a Garmin 705 this doesn't matter, but for people considering the Elite+ model with the stock CPU, this is something to consider.On my power computer I display power, heart rate and cadence. It is extremely difficult to achieve proper pacing at intensities above your threshold power; this is where a power meter could become an appreciated training partner. If you are training based on power, speed can be fairly irrelevant. A heart rate monitor would be just as effective..From what I read on Saris's site, the Comp is the old Pro+ without Ant+ and with a steel freehub shell. However I can tell you that the Garmin 305, 705, etc. I think you are right.. The only think not included in the box is the chest strap. Which can be found elsewhere The straps are the same and you just need to learn or rescan to pick it up.

  • Power Training For Sporting Bicyclists

    As you’ve probably realised by now, whether you're a full on racer, a century rider or you merely want to keep up with with the regional chain gangs, it’s vital to fully grasp the method that you are working out upon the cycle. A good deal of riders fully understand handlebar computers, pedal rotation meters and heart displays and though these kinds of are great equipment they aren’t consequently a sign of what that you're carrying out relating to actual work load. Here we intend to examine implementing specific zones one through to four and acquire an knowing of the sweet spot as an introduction to working with power gauging methods as an aid to bicycle coaching.
    If you've a Powertap or you are considering owning one then it's fundamental to know using it as compared with just slinging it on the bike and focusing on the data. The key point to understand is where your own ‘Lactate Threshold’ is, which we call as zone four. This is the middle place in which your own body chemistry is able to only support a given effort for 10-20 minutes. It is where you are performing at a high level of overall performance and it’s where your body commences to break-down. It’s such an necessary coaching rating that anytime you acquire your PowerTap this is one of the first tests you'll need to plan by undertaking a zone four testing protocol which unfortunately consists of consistently riding as hard as you can manage for 20 minutes while not conking out to acquire your wattage statistics in watts directly at your current LT.

    Immediately after you are aware of your threshold number the various other training zones turn out to be considerably more painless. To illustrate if you already know your threshold is 400 watts and your current training log tells you you're due a zone 1 active recovery day you're able to want to complete a ride at just 55% of your LT that will be 220 watts. A great number of bikers actually begin a recovery session and spend a large amount of power, defeating the reason of the recuperation ride and risking potential weariness so trying to keep your power level at or just underneath your advised electrical power is appropriate.
    Taking a zone 2 session that will typically be 60-75% of your threshold wattage which in the event of the 400 watts lactate threshold will be 240 to 300 watts which on paper you really should be in a position to endure indefinitely, energy permitting. This can be a great level to train in for the the greater part of your time but it will require a lot of time which mixed with today's life-style is improbable for many individuals with careers, loved ones and so forth. Which is why it's highly recommended to spend much more time in the zone 3 location working on rides widely known as ‘tempo’ which would be 80 - 90 % of your LT. This is an important zone given that that’s the work you will be utilizing in an event however , you aren’t deteriorating at lactate threshold therefore it is more supportable. It’s not going to be likable having said that it’s not going to be so tough you simply can’t do it. In the event that you’re out riding watch exactly what transpires regarding your current wattage ,a number of cyclists will use up an excessive amount of hours in zone 3 and not get into what is recognized as the ‘sweet spot’ that is a very little opening of 5 to 10 watts just beneath their threshold but which they may more or less hold with out their physical structure breaking down. You can easily incrementally expand your wattage by a few watts until you locate this sweet spot at the moment which in turn will possibly not appear to be much but during a 50 mile cycle those handful of watts will offer a specific bonus above your rivals.
    An additional benefit of understanding this sort of PowerTap coaching is it produces a brilliant signal of what your whole body is performing so that on your recovery days if you are having difficulties to access your recommended recuperation level then you're certain you must be resting instead of working out.

  • Powertap Review Data

    I've had this wireless PowerTap for a few years now and have had to send it back to Saris a couple times.4 is like a coach in a hub. Thanks to its wireless technology, I can switch it among test bikes at will (the swap requires only two new zip-ties for the head unit, plus changing rear wheels) or easily remove the PowerTap wheel in favor of condition-specific wheels on race day.g.4 is my favorite. Yes, this means that I sometimes train at 90 or 100 watts average since I rarely hold 200 watts average for 30 minutes or more. Watts are not effected by wind, tire rolling resistance, slope of the road and rider weight. Once PowerTap was under Saris ownership, things started to change for the better. Since then, this hub has been rock solid. There are too many variables with training only by heart rate. You just put the wheel in, turn on the computer and watch your power numbers show up. Since the majority of PowerTap power meters became wireless, we have seen the number of service issues that require the units to go back to the factory for service be dramatically reduced and this number has decreased further since the ANT+Sport compatible units started shipping in 2009. It does most everything I need it to. For this test, I laced the 416-gram hub to an American Classic Sprint 350 rim (about 350 grams). Power readings are available as peak, 5 second best, 30 second best, 1 minute, 5 minute, 30 minute, and 120 minute bests. Any ANT+ Sport cycling computer head may be used with the current generation of wireless PowerTap and older wireless versions can usually be upgraded with a ANT+ conversion firmware update for about $100.PowerTap systems vary widely in weight.. Two weeks later you averaged 240 watts and had an average speed of 20. Unless you are on a tight budget, you may want to consider a Garmin computer head or the CycleOps Joule 2. Overall, you can't go wrong with a PowerTap. You had a slower average speed but you pushed more watts. owerTap wireless installation is about as simple as it gets, all you need to do is install the wheel in your bike and mount the computer mount on the handlebar. In races, I found I could do 450 watts for a minute, once 500. So if you really want to get the most out of your training, or just want to get real information you can track and follow for years, you have got to look into the Power Tap SL 2. The wired PowerTap Comp is available online for $599.99. Mention this review and receive $25.00 off the purchase of the Power Tap SL2. Speed and cadence data is hard to interpret - there are too many variables to be able to extrapolate data from these numbers. The Power Tap comes ready for Campy and Shimano cassettes, 24,28, 32 and 36 hole rims. The two highest priced ones are the SL+ and the SLC+..99 and $2,099. I blow at 170-173 or so.

  • Powertap Powermeters

    Just riding with a powermeter you really get an appreciation of how variable you power output can be. Initially people tend to think there is something wrong with their bike, when in truth the answer lies in their bike set-up, fitness, and pedal stroke.
    The PowerTap SL collects huge amounts of data during your training ride. Additionally, a few years ago I started to use pacing in running, but only for interval training sessions, as a way to add to measuring my performance. Knowledge is that key element.

    PowerTap SL is a lighter version of the original PowerTap. Let’s start off with the basic concept of power and what it means to you. This is okay, when stomping, you are using primarily your gross motor quadriceps muscles to move the pedals and one pedal is “getting in the way of the other”.
    As well as long rides I have been trying various intervals using Andy Coggan's (ex physiologist, coach and competitor) levels of training.
    Look at it this way, when you go to a gym for the first time and start a weight lifting program you don’t know how much weight you can lift, but your gym instructor tells you to lift a certain weight 10 times. Either technique will lead to increased power production and subsequently increased speed on the bike. The generalized reason for the increase in efficiency is because you are recruiting more muscle fibers in synchrony and ultimately more efficiently physiologically.. Start with a steady warm up to optimize recruitment patterns and get the lungs, leg and cranium ready to ride. This is why I think I will do a test for each type of aerobic effort rather than base my training off the max mean power for any duration. If you know your actual performance, you know how far you are from your goals and if the goals are realistic. For safety and biomechanical reasons, when doing single leg isolations, just let the other leg float on the pedal instead of clipping it out.
    Various sources have suggested 80-85% is a good figure to start at. Allen Lim’s previous article on maximizing the off-season and how to pedal more efficiently.I did use lactate testing to determine HR training zones but can now see the high variability with HR and how many factors affect HR in comparison to power. For comparability sake, try to repeat as many of the same variables as possible (sleep, nutrition, time of day, temperature, terrain, etc. .Dmax has also correlated highly with the Functional Threshold.Steadier rpm ranges.Increase in working wattage. This figure predicted performance in my riders in both 2k Pursuit and road TT better than any other figure.
    Finally, look at your data objectively to decide what you want to work on.
    The meter can also be used to track ones progress on various courses. It is only when we identify our opportunities can we create positive change, adaptation, and greater fitness with less effort.
