This year has seen the launch of a number of lightweight, all-rounder road racing bikes that can hit the UCI’s minimum weight limit of 6.8kg. Plaintiff’s approach hews more closely to precedent, especially that of this district. As acknowledged by Judges Young and Woodlock, however, in Reddy and DePaoli, it would be well within the Court’s discretion to provide some verbal construction at a reduced level of detail than that proposed by defendant. The question in this case, therefore, is primarily the “level of detail” to be used in describing the claimed design, i.e. whether the Court should advert to the illustrations in the design patent or undertake an element-by-element description thereof.

The latest Giant Propel Advanced SL 0, for example, weighs just 6.91kg (size ML, without pedals) – only around 200g more than an equivalent TCR Advanced SL 0 (6.71kg, size L, without pedals). Ultimately, whatever the physics says, it’s hard to beat the experience of picking up a featherweight bike and imagining how it might improve your climbing. Bike weight makes almost no difference to performance if you’re riding along a flat road.

Of course, it’s the climbs most people care about, but even then, shaving a few hundred grams off a bike won’t transform anyone from a rouleur to a grimpeur. Giant also developed a new ‘ThinLine’ lightweight paint, bringing the total weight savings hyper bike to 140g versus the already very light 2020 TCR Advanced SL Disc. On top of this, Giant says it uses lasers rather than machine stamping to cut its carbon fibre sheets and now employs robotics to automate certain aspects of the carbon layup. Rather than using off-the-shelf options, Giant says it weaves its own carbon fibre to its own specification, in its own composites factory. For the latest generation of its all-rounder racing bike, the Tarmac SL8, Specialized said it took inspiration from the Aethos.
However, your bike typically makes up such a small percentage of the overall system weight, that a slightly lighter bike doesn’t move the needle much. Despite this, Specialized says changes to the leading edges of the bike, such as the fork, head tube, and a new lighter and more aerodynamic integrated cockpit, make the Tarmac SL8 more aerodynamic hyper mountain bike than the S-Works Venge, Specialized’s last dedicated aero road bike – an impressive feat. Nevertheless, there have been some technical developments in recent years that are enabling brands to build lighter bikes than before. First, the move from rim to disc brakes added a few hundred grams (or more in some cases) to most road bikes.
E-bikes are here to stay, without a question, and as a result, a limitless selection of devices that claim to be the greatest of their kind have emerged. One company, Hyper Bike Co., aims to increase market access to e-biking by providing reasonably priced and decently equipped electric bikes. We previously talked about its E-Ride eMTB, which retails for just $1,500 USD. Now, it’s entering the world of urban commuting with the Ultra 40. Before the mass adoption of disc brakes on road bikes, for example, many pro-spec road bikes weighed less than 6.8kg and this was not widely considered unsafe. A rider’s power-to-weight ratio is critical to climbing performance.
