With the dominance of road disc brakes<\/a>, the latest generation of Zipp wheels don\u2019t have to account for a rim-brake surface, so they\u2019re wider and, according to Zipp, better shaped for a smooth interface between the rim and tyre.<\/p>\nAccording to Zipp, the move to a hookless rim<\/a> also helps provide a smoother rim and tyre combination, reducing an area of high turbulence and, therefore, drag.<\/p>\n ![\"""\"]( "\\"\"\"\\"\/")

While the revised shape of the rim, and the introduction of hookless technology, improves aerodynamics, Zipp says there\u2019s also a benefit in saving weight.<\/p>\n
The weight savings here are impressive, with 282g saved on the 808 and 243g on the 858 NSW.<\/p>\n
Where these were wheelsets used primarily in time trials, triathlons or fast road races, the new claimed wheelset weights of 1,635g (808 \u2013 752g front, 883g rear) and 1,530g (858 NSW \u2013 719g front, 811g rear) put these in the realm of general road racing in favourable wind conditions (they\u2019re still super-deep rims, after all).<\/p>\n
Rolling resistance<\/h3>\n\n ![\"""\"]( "\\"\"\"\\"\/")
<\/source><\/source><\/source><\/source><\/source><\/source><\/source><\/source><\/source><\/source><\/source><\/source><\/source><\/source><\/picture><\/div> The new design leans on the trend for wider road tyres.<\/span><\/figcaption> Zipp<\/i><\/span><\/div>\nThis is where things can get interesting. For years, road riders thought that a narrower tyre, pumped up to a high tyre pressure on a road bike<\/a>, was the fastest option.<\/p>\nThe latest research<\/a>, however, has shown that it\u2019s better to go wide \u2013 within reason \u2013 to reduce rolling resistance. It\u2019s a trend we\u2019ve seen everywhere from size availability on the best road bike tyres<\/a>, to the latest Tour de France machines<\/a>.<\/p>\nA tyre contact patch relates to its rolling resistance, and the contact patch is defined by rider weight and tyre pressure. For instance, if you take two bikes with the same rider and two different tyre widths but the same pressure in those tyres, the contact patch would be the same because they\u2019re both supporting the same load with the same amount of pressure.<\/p>\n
The big difference is in the shape of the contact patch. A wider tyre will produce a wider but much shorter contact patch compared to a narrow tyre. That means less \u2018sag\u2019 in the tyre, deforming the tyre less, and less energy lost when rolling.<\/p>\n

The final piece in the TSE puzzle, and one Zipp identified as being able to bring big efficiency gains, covers vibration losses.<\/p>\n
For example, while the new 858 rim shape is only one watt more aerodynamically efficient, according to Zipp, the brand\u2019s real-world testing has shown gains of eight watts for the 858 and five watts for the 808 when it comes to vibration and rolling resistance improvements.<\/p>\n
While running a wider tyre at a lower pressure helps, Zipp says there\u2019s also a contribution from the new rim construction, called CiR (Carbon internal Reinforcement). It\u2019s an idea borne out of Zipp\u2019s \u2018Nest\u2019 development lab, which allows the quick development and testing of fully functioning, prototype rims.<\/p>\n
Most carbon wheel designs (including Zipp\u2019s previous ranges) used a rim with a uniform thickness throughout. However, Zipp\u2019s testing and analysis has shown that forces acting on a rim are not uniform. As a result, the CiR design places material where it\u2019s needed and removes any excess material. The finalisation of this design apparently took more than two years.<\/p>\n
The final design is best described as having an internal skeleton that\u2019s wrapped with a fine carbon skin, much like the wings of an aircraft. The result is not only a rim that\u2019s 10 per cent lighter than the previous model, even though it\u2019s wider, but one that\u2019s also significantly more flexible in its sidewall.<\/p>\n
That means better absorption of vibrations from the road, and a less fatiguing ride as a result. Zipp also says it\u2019s more efficient because the tyre stays in contact with the road surface rather than skipping and bouncing across it. This all adds up to a faster wheel, despite losing the focus on aerodynamics.<\/p>\n
