Product Review - Zipp 808 Carbon Clinchers |
 |
 |

Brief Version
This is a perfect wheel set for triathlete and road racers seeking superior aero performance, stable handling, and the convenience of clinchers. There’s no faster all-around wheel set than the 808 Carbon Clincher.
The new carbon clinchers has the new firecrest shape, that is not affected by crosswinds, and the only approved full carbon clincher that can withstand high temperatures of braking.
More Detail....
To achieve maximum performance with every Zipp wheel set, our engineers create uniquely tuned rim profiles for every combination of rim depth and tire style. So the process of developing the all-new 808 Carbon Clincher was much more complex than merely adding clincher sidewalls to the 808 Tubular or increasing the depth of the 404 Carbon Clincher.
Optimizing the revolutionary Firecrest aero rim concept for a 81mm depth and the distinct airflow pattern of clincher tires required us to evaluate a slew of minutely varied prototypes through computational fluid dynamics and in the wind tunnel. At 27mm wide, the final version is the fastest deep-section carbon clincher in the world. Yet, with a weight of only 1759 grams, it more than holds its own on the climbs.
With Firecrest’s unparalleled approach to the wheel’s centre of pressure, the 808 Carbon Clincher also handles crosswinds with the stability you’d normally associate with a much shallower rim– making the 808 Carbon Clincher ideal for non-disc-legal courses like Kona. Plus, the wide rim shape provides efficient power transfer along with comfort and durability – making it an excellent choice for just about any terrain and riding style.
In addition to Firecrest, all Zipp full-carbon clinchers feature an exclusive heat-resistant resin as part of the composite structure. Utilized in the 808 Carbon Clincher, this technology prevents spikes in rim temperature and tire pressure that can impact performance and handling. In fact, heat dissipation is improved so substantially that ours are the only carbon clinchers to pass stringent European safety testing without limitations on rider weight or brake pad options. So every rider can tackle even the longest, most technical descents with confidence.

Nutrition Tips - Is Snacking better than 3 Meals/day? |
 |
 |
Are you a Labrador or a Budgie?
I usually classify active individuals and athletes into two eating groups “Labradors” and “Budgies”. Labradors (usually males) sit down to eat meals quickly and continue to eat until they are so full they can’t move. Budgies (usually females) sit down to eat meals and usually only eat a portion of the meal. Labradors rarely eat between meals but when they do eat they eat enormous quantities. Budgies on the other hand eat small amounts at main meals and consume large amount of calories between meals. Which one are you? The way you eat can have a large impact on endeavours to change your body composition for training outcomes.
Snacking - Budgie’s
There is good evidence that the more often an athlete eats, the more energy they eat in a day. There is also evidence that suggests that when we eat an afternoon snack in an attempt to reduce our evening meal intake we still eat what we would have eaten without the snack. This is an issue as snacks foods are usually high in carbohydrate and energy and low in fibre and protein.
Snacking is a major issue in today’s society due to a few key changes in the way we deal with food.
• We now have open planned kitchens which means the area in which we consume food has increased dramatically, eg in front of the TV, in the lounge room etc. We have no defined areas in our house for food consumption.
• Increase in food serve sizes eg. 200g instead of 100g of yoghurt, 600ml of soft drink instead of 300ml, coffee in a mug instead of a cup.
• Snacks usually only contain 1 ingredient meaning that it is easy to continue to snack on it without formal preparation.
• Snacking has no structure or preparation involved. You grab something quickly like a handful of rice crackers but as you pass the cupboard again you grab another handful. Within minutes you have eaten the whole packet of rice crackers.
On the other hand snacking can be important in sports nutrition for providing recovery nutrients and for pre-training carbohydrate priming. So it is important if you are consuming snacks for training purposes eat snacks that are purposeful, of appropriate quantity, have more than one ingredient, are higher in protein and are eaten at a table or in the kitchen. If you are not snacking for training and trying to change your body composition then you may benefit from sticking with the three main meals a day and trying to avoid snacking.
Main meals - Labradors
It is easy (as Labradors can attest) to sit down to a meal high in refined carbohydrate, the occasional veggie and minimal protein and eat until your eyes pop out. You consume large amounts of calories and don’t snack in between meals. For some active people and athletes this way of eating is necessary to consume the calories required to deal with high training volumes. This is not the most effective way to eat especially if you are trying to reduce excess body fat. But Labradors often complain of being hungry after main meals when they try to eat smaller volumes. You can overcome this by using a few tricks.
• Eat a larger portion of lean meat/chicken/fish or other high protein low fat food.
• Eat more vegetables. Ideally vegetable portions of the meal should make up 50% of the meal.
• Control your carbohydrate portion, measure it out or keep it to a portion of your plate eg 25% of the plate is carbohydrate.
• Consume water with your meal. This can fill you up without adding calories.
• Slow down your eating and put down your knife and fork between mouthfuls.
• Over time your stomach will learn to deal with the volume you provide.
By reducing your main meal sizes you may need to increase your purposeful snacking for specific high intensity sessions. This is not mindless snacking, this is eating snacks that have specific nutrient compositions and follow the rules set out above for snacking.
What can Labradors and Budgies learn from each other.
Budgies can learn that eating more at main meals may reduce their need to snack inadvertently throughout the day. Labradors can learn that more specific snacking around training and during training may help reduce the size of their main meals. Snacking and eating bigger main meals both have their place in a well balanced training diet but it is when the extremes are taken that people get into trouble.
