Quarq DZero DUB Powermeter SpiderThis powermeter spider is engineered for precise results and dependable performance, whether you're training for an event or trying to push yourself to reach new goals. Feature-packed with many of Quarq's finest technologies as well as ANT+ and Bluetooth Low Energy (BLE) connectivity, it allows for your data to be transferred wirelessly. Another highlight is its MagicZero technology, which automatically checks and recalibrates your power meter as you ride, so there's no need to manually calibrate. Measuring accuracy within 1.5% for both legs, it also has an IPX7 waterproof rating for training in all-weather conditions.Reach new goals and explore new roads with a power meter that delivers on accuracy, durability, and reliability. The Quarq DZero DUB is built with broad compatibility and will work with most 10 speed and 11 speed chainrings. Build the power meter that best fits your bike with multiple bolt circle diameter (BCD) options available to choose from as well as compatible crank arms, chainrings and bottom brackets available separately.DUB TechnologyThe relationship between bottom bracket spindle and bearing is the core of DUB technology. It's where stiffness meets durability. We took it a step beyond conventional thinking and made everything simpler—better integrating the relationship between chainring, crank, spindle and bottom bracket. It's this approach to developing a complete system that equals better drivetrain performance.DZeroQuarq's next-generation DZero power meter platform is named for the D0 Experiment, one of science's most accurate and innovative projects to detect subatomic particles moving at the speed of light.Please note: This product includes the powermeter spider only.

Quarq DZERO Road Power Meter ChainsetFeaturing two high-quality carbon crankarms, this powermeter offers exceptional stiffness, strength and low weight performance on your road bike. Quarq has also equipped this model with two SRAM X-Glide aluminium chainrings for additional durability and precision as you clock up the miles. Designed for compatibility with most 10 speed and 11 speed drivetrains, this powermeter is fitted with a Quarq DZERO DUB spider power meter that delivers accuracy within 1.5%, measuring both legs. Another highlight is it comes complete with many of Quarq's renowned technologies such as MagicZero, AxCad and OmniCal as well as 10K Temperature Compensation and an IPX7 waterproof rating for accuracy and consistency in any weather conditions. DZERO Road Powermeter with X-Glide ChainringsImagine being able to shift smoothly at any time, no matter what. We're talking full-power shifts. Up, down, whatever the road demands. The benefit of X-Glide chainrings is simple, yet, when you think about it, incredibly impactful to the way you ride. Flawless shifting means you'll never again compromise your speed and power in unpredictable road conditions. Quarq precisely paired the different-sized chainrings and redesigned where and how the chain engages with the rings. By aligning the chainring pick-up rivets to the chain pivot pin—rather than the middle of the chain link—you get double the shift opportunities. No more missed shifts, ever. X-Glide puts you in the right gear, right now.Bluetooth and ANT+ CompatibleYour riding and training efforts deserve power measurement that reaches the highest standards of accuracy to help you reach personal records. Because without accurate data, you can't know if you are making the progress you're aiming for. With Quarq's premier DZero power measurement technology that uses Bluetooth and ANT+ connectivity, you'll have the technology to get real results.Reach new goals and explore new roads with a power meter that delivers on accuracy, durability, and reliability.

Oft called out jokingly in his Venetian dialect and addressed to athletes and employees to spur them on. Eco-PerformanceWith their recycled microfibre upper and a bio-based resin finish derived from cereals, the Sidi Shot 2 Dzero Cycling Shoes combine an environmentally friendly finish with the usual light, supple and efficient performance you'd expect of a premium road shoe. From the endurance demands of long training rides to the lung-searing efforts of criterium racing, the supple upper offers immediate comfort and the carbon fibre sole offers uncompromising stiffness for immediate response to your pedalling inputs. C-Boost SRS Carbon SoleThe performance heart of the Shot 2s is the C-Boost SRS Carbon Sole. Designed to deliver uncompromising performance, this carbon sole has a carefully engineered shape and a carbon lay-up that delivers direct power transfer, leading to lightning-quick acceleration and rival-dropping pedal strokes.Cleat extension has been increased ± 5 mm to allow for more cleat adjustment while the millimetre scale allows you to get the right position every time you replace your cleats. SRS (Sole Replacement System)The SRS sole features replaceable inserts in Nylon and TPU. These inserts provide protection for the carbon sole in the areas most prone to wear and damage and boost durability and grip when you're walking. Ventilation holes are fully integrated too, ensuring excellent air circulation during every pedal stroke. Double-Techno-3 Push Flex SystemWith the Double-Techno-3 Push Flex System, Sidi has created a quick and easy adjustment system that is also engineered to eliminate pressure across the instep.Being positioned centrally, you'll also benefit from more even closure pressure between the inner and outer sides of the shoe, securing your foot for an incredibly stable pedal stroke. Micro-adjustment and easy release make this a system you can use easily on the go too - tighten up for the sprint - loosen up when it's hot. Reflex Adjustable Heel Retention DeviceEnsuring there's no heel slippage and as a result, no loss of pedalling efficiency or discomfort, the Reflex adjustable heel retention device is easily adjusted to suit your foot shape and preference. Sprinting, climbing or driving the peloton, enjoy firm foot-hold.
