Introducing the DBAIR , an all new twin-tube inline shock with superior performance and reliability. The first shock to feature Cane Creek’s LinEair Spring, the DBAIR is the best of both worlds, an air shock that feels more supple, linear and seamlessly supportive throughout its travel.When developing the DBAIR , Cane Creek's engineering team brought forth great advancements in their design and manufacturing processes, all devised to make DB shocks more robust compared to the previous generations. The fully loaded functions of the DBAIR far outstrips other inline shocks and now offers even greater performance and reliability to unleash the full potential of trail and enduro bikes.The DBAIR IL is the first shock to feature Cane Creek’s LinEair Spring.

Shimano Dura-Ace R9150 Di2 11sp Rear DerailleurCombining the very best of Shimano’s electronic shifting technologies with its race-proven mountain bike “Shadow” cage design, the Dura-Ace R9150 Di2 road bike rear derailleur shifts in an instant and has enhanced aerodynamics. The updated cage position means it rests directly under your frame’s chainstay, reducing drag and protecting it in the event of an unfortunate racing incident.The Shadow design also offers faster wheel changes thanks to the fact that it moves the derailleur out of the way of the dropouts. It also offers faster and more precise shifting than ever before. Shimano's 9150 groupset brings its Syncro-Shift technology to the road too. Syncro-Shift technology enables the front derailleur to read the position of the rear derailleur. The front shift is then automatically operated to position the gears in the most efficient gear and best chain line. This means you'll never have to worry about front shifting and correction shifts again.Features: Speed: 11-Speed Compatibility: Shimano Di2 road shifters (Dura-Ace and Ultegra with E-tube connection) Maximum Low Gear Sprocket: 30T (Minimum 25T) Minimum High Gear Sprocket: 11T (Maximum: 14T) Maximum Front Difference: 16T Total Capacity: 33T Mount Type: Standard hanger mount Clutch Type: No Ergonomic shifting operation without stress Shimano synchronised shift Low profile rear derailleur design Shimano Shadow cage design Race endurance for less damage in a crash Maintains compact and smooth appearance Manufacturer's Part Number: RD-R9150 Weight: 204gA 2 year warranty is offered with all Shimano products from Chain Reaction Cycles (3 years on Dura-Ace and XTR products).Buy Shimano Components from Chain Reaction Cycles, the World's Largest Online Bike Store.

Favero Assioma DUO-Shi Power MeterThis high-quality power meter is engineered for accuracy and consistency, whether you're training for an event or trying to beat your personal performance goals. It features an aerospace aluminium alloy construction, which makes it tough and dependable as you tackle every mile of road. Favero has also ensured that each power sensor is protected by a bi-component resin block that's extremely resistant to shocks and completely waterproof. Another highlight is it's simple to install and move from one bike to another just like your normal pedals. You can do it easily and without extra tools or the need for a mechanic.Dual-Sided Power MeasurementSpecifically designed for use with Shimano pedal bodies, this model is compatible with Shimano PD-R8000, PD-R7000, PD-6800, PD-R550 and PD-R540. It features power sensors for your right and left pedal to offer real dual-sided power data by measuring power individually for both legs. This makes it possible to observe with accuracy not only Total Power, but also L/R Balance, Torque Effectiveness (TE), Pedal Smoothness (PS), etc. Assioma also guarantees accurate and consistent data in all conditions on the road, and at any temperature ranging from -10°C and 60°C, thanks also to the Automatic Temperature Compensation (ATC).Unlike others, the measurement of Assioma is not affected by errors related to very irregular pedalling (e.g. uphill sprints) or the use of oval chainrings. This is because Assioma can detect the actual instantaneous angular velocity during the whole pedal stroke, thus providing ±1% accuracy in any conditions. Not only in the lab.Bluetooth and ANT+ ConnectivityAssioma communicates with bike computers and smartphones (both Android and iOS) via Bluetooth and ANT+. Assioma is the only pedal-based power meter for road with integrated rechargeable batteries; a single charge ensures at least 50 hours of use.Please note: Compatible Shimano pedal bodies are sold separately.

Hex key and 4 washers for the installation. Assioma user manual. Assioma DUO-Shi user manual.Technologies: Designed for the compatibility with Shimano road: Assioma DUO-Shi has been designed for Shimano road users, as it offers the opportunity to keep on riding with your current Shimano pedal bodies* without giving up on the trustability and precision of Assioma. Installation into your own Shimano pedal bodies: Installing Assioma DUO-Shi into your own compatible Shimano pedal bodies* is simple and quick. Compatible Shimano pedal bodies: Assioma DUO-Shi is compatible with the following Shimano pedal bodies: PD-R8000, PD-R7000, PD-6800, PD-R550 and PD-R540. Increased Q-factor?: The Q-factor of Assioma Look version is of +54mm, whereas that of Assioma DUO-Shi measures +64mm with the PD-R7000/R550/R540 pedal bodies and +65mm with the PD-R8000/6800. Despite an initial concern related to the increase of the q-factor, we decided to proceed with the project considering that body size (height, pelvis width, etc.) is a subjective factor contributing to determining which is the best q-factor for each one of us. A final, positive feedback from our beta testers has eventually validated the product. Easy to install: Install and move your Assioma from one bike to another just like your normal pedals. You can do it easily and without extra tools or the need for a mechanic. IAV Cycling Dynamics: Assioma provides advanced metrics called IAV Cycling Dynamics: IAV Power Phase and IAV Rider Position. These metrics, combined with the classic power data permit you to analyze in detail your pedaling technique and how your position on the bike influences performance. IAV Power and gyroscope: Unlike others, the measurement of Assioma is not affected by errors related to very irregular pedaling (e.g. uphill sprints) or the use of oval chainrings. This is because Assioma can detect the actual instantaneous angular velocity during the whole pedal stroke, thus providing ±1% accuracy in any conditions. Not only in the lab. Bluetooth and ANT+: Assioma communicates with bike computers and smartphones (both Android and iOS) via Bluetooth and ANT+. Real dual-sided power data: Assioma DUO-Shi measures power individually on both legs; this makes possible to observe with accuracy not only Total Power, but also L/R Balance, Torque Effectiveness (TE), Pedal Smoothness (PS), etc. Accuracy and consistency: Assioma guarantees accurate and consistent data in all conditions on the road, and at any temperature ranging from -10°C and 60°C, thanks also to the ATC (Automatic Temperature Compensation). Waterproof and resistant: The power sensors are protected by a bi-component resin block, extremely resistant to shocks and completely waterproof. Rechargeable and green: Assioma is the only pedal-based power meter for road with integrated rechargeable batteries; a single charge ensures at least 50 hours of use. Tested and guaranteed: Favero Electronics produces every power meter in-house and tests each of them thoroughly to fully satisfy the standard required by current regulations.Manufacturer's Part Number: 772-02-S Black/Grey Dual Side Sensor ShimanoBuy Favero Components from Chain Reaction Cycles, the World's Largest Online Bike Store.
