Last Summer, we saw the return of Maguras Luise Elite 4-piston brakes. But, at the time, they were only available on complete bikes. That is, until now. The Louise Elite 4-piston brake is now available for individual purchase through your favorite bike shop. The Louise Elite is a brake that targets both urban commuters and mountain bikers who are looking for reliable 4-piston stopping power across different types of riding scenarios.(Photos / Magura)The Louise Elite 4-piston brakes feature one-piece forged aluminum calipers that are paired with 2.0mm thick rotors. This creates a rigid system where the rider feels their hand force transfer directly into braking power.The one-piece caliper design helps prevent leaks and also provides heat resistance and consistent performance, whether youre navigating city traffic or tackling demanding trails.Plus, Magura also backs their brakes with a 5-year leak-proof warranty on both the master cylinder and caliper. The Magura Louise Elite has a couple of cool, standout features. The first being, the brakes master cylinder is fully compatible with Bosch eBike ABS systems for both Touring and Trail modes, offering increased oil flow volume for precise ABS function.The second is Maguras Easy Link technology, which offers a tool-free hose connection system, speeding up installation by a claimed 40%. This tech also simplifies maintenance through its master cylinder and brake hoses easy, plug-and-play design.Magura Louise Elite Retail & DetailRetail: $127 (110)Caliper: one-piece forged, 4-piston, AluminumBleeding: Bleed screw on the caliper, valve retrofittableBrake Master: Carbotecture, EASY LINK hose connectionABS compatibility: Bosch eBike ABS readyRotors: MAGURA 2.0 mm rotors Brake pads: MAGURA MDP 9 GREENBrake hose: MAGURA Disctube 2.2, rotatableBrake lever: MAGURA LOUISE ELITE, Carbotecture, T25 reach adjustClamp: Carbotecture, one-piece, Shiftmix IGWeight: 250 g (*100 cm hose, incl. clamp)Warranty: 5-year leak-proof warrantyGet more details and check out everything Magura has to offer.Magura.comThe post Magura Louise Elite 4-Piston Brake is Back, Affordable & Available for Aftermarket Purchase appeared first on Bikerumor.

Jessica Disley breaks women's UCI Derny Hour Record in Newport

Michael Valgren has won stage 5 of Tirreno-Adriatico, one of the rare instances this year in which a breakaway has won in a top race. The Danish classics specialist has ridden himself into his first win since 2021. In the peloton it was a conservative race, however Isaac del Toro attacked the final...

The ability to adjust tire pressure on the fly is potentially game-changing, and weve seen a few different Tire Pressure Management Systems (TPMS) in the past few years. From the UCI-approved Scope Atmoz to the Gravaa KAPS system, these functional pressure-adjusting hub systems have shown more than just promise. But even a few high-profile race-winning performances using the Gravaa system werent enough to keep the brand from going under. It seems that price has been a hurdle preventing TPMS from wider acceptance and commercial success (as well as tubeless compatibility).Which is why I was intrigued when a Swiss inventor named Bernhard Buergler reached out the other day with information regarding his new TPMS patent. In the press release shared by Breugler, he states that his recently patented design (WO2025/261588) represents the next generation of TPMS, which will help keep these systems alive while making them more affordable, and therefore, more commercially viable.Drawings from the published patent are somewhat vague, but they convey the concept. Figure 2 is a planar chematic representation of the invention on a bicycle.From the Patent Abstract: The present invention relates to a device for adjusting pressure in tires (19) of a vehicle during operation, comprising a source of pressure (10a, 10b, 10c); an inflow valve (12) for regulating the flow of gas from the source of pressure (10a, 10b, 10c) to the tire (19) and thus increasing the pressure in the tire (19); an exhaust valve (13) for regulating the flow of gas from the tire (19) and thus reducing the pressure in the tire (19); a wheel hub unit (30) able to control the flow of gas to and/or from the tire (19); and an electronic control sys- tem (21) in communication with and able to control the source of pressure (10a, 10b, 10c), the inflow valve (12), the exhaust valve (13) and the wheel hub unit (30) in order to increase and/or to reduce the pressure in tires (19).Figure 3 is described as: A pneumatic scheme of the invention shown in Figures 4 and 5.He believes that his system addresses the two major weaknesses of previous systems cost and complexity. In the press release, Buergler claims his TPMS is radically simplified compared to previous designs, and that by using off-the-shelf industrial components, Buergler has drastically reduced the projected retail price to just 20-30% of previous systems.Unlike the Gravaa system, which essentially generated energy to power a small air compressor, in Buerglers patented design, the hub-mounted device contains a refillable tank for liquid CO2 and an array of micro-nozzles and orifices, which allow for the rapid inflation and deflation of a bicycle tire during operation. Given that CO2 would be used for inflation, it would ultimately be limited in its inflationary capacity, but it might also inflate more rapidly than a tiny hub-based air compressor (and perhaps be lighter weight).Buergler claims the massive cost reduction is driven by a radical design simplification and a highly complex, yet inexpensive, 3D-printed manifold. Like other systems, a tube would still need to extend between the hub and the rim/tire for inflation and deflation. Additionally, a handlebar-mounted control unit would be used to control the device, preferably communicating with the device via Bluetooth or another appropriate protocol.Figure 5 is a perspective view of another preferred embodiment of the invention.The patent description goes on to say, According to another embodiment of the invention, a battery-operated micro air compressor is used as a pressure source. For this embodiment, certain downstream components, in particular the pressure orifice, can be omitted or simplified in its specifications. So, perhaps a mini-air compressor and a compact, rechargeable battery could be used instead of CO2, like a hub-based version of a portable electric tire inflator.Its important to note that so far, this newly patented TPMS design is just that, a design. There are still plenty of questions related to inflation capabilities, rates, the weight of the system, and the controls. But those are questions that cant really be answered until the prototypes have been made. But, assuming its functional and reasonably priced, it could potentially decrease one of the major barriers to greater market acceptance of tire pressure management systems.Buergler is offering his patent for sale and is currently seeking an established industry partner to help bring it to market.
