Air-Liner Inserts support tubeless tire performance, lock the bead to prevent burping, and reduce the risk of rim strikes and pinch flats. By taking innovation to the next level and creating the world’s best tires,we’re on that journey too. November 24, 2023, heralds the arrival of Black Friday, a shopping phenomenon that consumers eagerly await. Amid the plethora of offerings, the eBike sector assumes a prominent role.
While the Dura-Ace Di2-equipped SL8 we have in for review weighs 6.76kg in a size 56cm, without pedals or accessories, Specialized says a special-edition, size-52cm version built for Remco Evenepoel to take on this year’s Vuelta a España weighed 6.8kg ready to race. That innovative approach takes inspiration from beyond the realm of conventional two-wheelers, drawing from the designs of high-performance hyper bicycles cars. It doesn’t just adopt design principles known in the bicycle industry but also benefits from Aston Martin’s know-how in the supercar and hypercar programs. This can be seen, for example, in the pierced stem, which mirrors the side strake of the Aston Martin DB12. Customers will have a choice between 12-speed groupsets from companies like Shimano, Campagnolo, and Sram Red.
In 2022, the opening stages around Copenhagen were pan-flat, meaning weight wasn’t a concern and riders went all-in on aero. They all have high-end components, but none resort to the kind of components or hacks now reserved mostly for dedicated hill climb bikes. The 2024 KTM 125 DUKE is your entry point to the DUKE revolution.
Beyond their environmental advantages, eBikes also offer distinct health benefits. These electric-assisted bicycles provide a versatile and accessible means of engaging in physical activity, catering to individuals of varying fitness levels. Riding an eBike encourages cardiovascular exercise, leg muscle engagement, and overall mobility.
When the 2021 Giant TCR launched, Giant claimed this enabled it to create the lightest set of carbon fibre sheets ever assembled for one of its bikes. In turn, each tube could be lighter, leading to a claimed weight of 685g for a size 56cm S-Works Tarmac SL8 frame – 115g less than an equivalent S-Works Tarmac SL7 frame. This impressively low weight was almost an afterthought, though – perhaps because Canyon knows it can build lighter bikes. All in, the new O2 VAM has a claimed frame weight (including the integrated seat mast) of 730g in a size 54cm, despite it retaining a number of aerodynamic optimisations. This was most evident when we weighed pro bikes at the start of the 2022 Tour de France in Copenhagen, Denmark.
It also made extensive use of digital design aids, such as Finite Element Analysis (FEA simulates how objects behave under various physical conditions) and Computational Fluid Dynamics modelling (CFD is akin to a virtual wind tunnel), and rapid prototyping. On top of this, the lightest bike we saw – Simon Clarke’s Factor 02 VAM – weighed just 6.925kg ready to race. Round tubes are typically more structurally efficient than aerofoil-shaped tubes, and can therefore be made lighter. In 2010, Jean Wauthier, a UCI technical advisor, told BikeRadar the limit was set taking into account “sensory-motor coordination, stability, balance, manoeuvrability, adherence, postural comfort, a vision-posture system and safety”. It was introduced as part of the UCI’s Lugano charter in 2000 (which also put a stop to a load of other fun things such as monocoque carbon frames and anything Graeme Obree did).
In the case of coated surfaces, there may be color differences due to the usual process fluctuations. The consumption values stated refer to the roadworthy series condition of the vehicles at the time of factory delivery. At our webstore, we offer frames, known for their quality and durability. Founded in 1990, Hyper Bicycles has been dedicated to producing high-performance bikes that meet the needs of riders of all levels and styles. Brands have always taken great pleasure in declaring their bikes “illegally light”, but if the minimum weight limit goes, so does the viability of this as a marketing strategy. Our former colleague, Matthew Loveridge, used to insist that a lighter bike “will always be more fun to ride, all else being equal”, for example, and the idea that modern road bikes are ‘too heavy’ is frequently raised in the comments sections of our website and YouTube channel.
Claim construction proceeds differently with respect to design patents. Design patents are typically claimed as shown in drawings, and claim construction is adapted accordingly. Egyptian Goddess, Inc. v. Swisa, Inc., 543 F.3d 665, 679 (Fed. Cir. 2008) (citation omitted). The Federal Circuit has instructed that a design patent’s claim is often better represented by illustrations than a written claim construction.
