Simple to use Auto Zero: every time you stop pedalling for 3 seconds or more your power2max "re-zeros", no need to re-zero manually. No cadence magnet needed: you dont need to install a cadence magnet on your bike. Your power2max calculates cadence precisely using its internal accelerometer. Battery change: when the time come to change your battery - after 300 to 400 hours of use (6,000 to 12,000km) - you can do it yourself. ±2% Precision Power2max power meters deliver state of the art data: they achieve an accuracy of ±2% or better including all environmental influences. Power2max power meters achieves this accuracy through a refined design and high quality manufacturing processes. Power2max manufactures the power meters in Germany with the highest quality production standards. ANT+ Power2max power meters use the ANT+ standard to transmit data wirelessly to your bike computer. The ANT+ standard guarantees reliable transmission and offers a large number of bike computers to choose from. Bluetooth ready Power2max FSA power meters are Bluetooth ready and can be upgraded to transmit the data wirelessly not only with ANT+, but also via Bluetooth communication (with purchase of firmware upgrade). Upgradeable Power2max FSA power meters can be upgraded to have the software feature of left-right balance
Already a legend in its time, the SRAM Red Exogram Crankset is now available with refreshed graphics to complement the new SRAM Red eTap componentry. The SRAM Red Exogram crankset features a completely hollow construction all the way to the spider. It's hidden bolt pattern makes better use of carbon fibre to further improve stiffness and shed weight. As always for seamless, flawless performance and Yaw compatibility, the chainset has been equipped with X-GlideR chainrings. The chainrings are designed for an optimised shifting performance with the Yaw front derailleur. The stiffer rings (5mm 7075-T6 aluminium CNC-machined) feature upshift rivets with an advanced design adopted from SRAM XX. CNC machining allows for precision control of each tooth shape, ramp, and nearly every shifting feature of the chainring. Chainrings, chain, and front derailleur are designed as a single integrated system for optimised performance.Arm Material: CarbonChainring Material: AluminiumBottom Bracket: BB30 (Not Included)Weight: 609g
The HollowTech II 12-speed Dura-Ace chainset offers the optimum balance of light weight and rigidity, making it the global choice for road racing's elite riders Hollow outer chainring, giving vast improvements in rigidity and increased weight savings The hollow outer chainring has essentially removed outer chainring flex, hugely improving shift performance making it precise even under high load These industry leading HollowTech II 4 arm cold forged hollow crank arms have been evolved to increase rigidity, reduce weight, and improve strength The teeth have been developed to work only in conjunction with the 12-speed chains for improved contact providing more efficiency and improved power transfer There is a wide range of chainring ratios and crank arm lengths available enabling customisation for all riders and racing disciplines HollowTech II integrated bottom bracket design uses a wider bearing placement and larger axle diameter for increased stiffness and efficiency Bottom bracket seal design has a minimal bearing interface gives superbly smooth rolling and increased durability
