Accurate Readings in all Conditions Shimano have extensively tested this new power meter system to ensure its accuracy and reliability in all weather conditions. The chainset is equipped with dual sided and internally hard-wired crank arm strain gauges, which provide a ±2% power measurement accuracy regardless of your pedalling position. Easy to Maintain The power meter is powered with a simple rechargeable battery for easy maintenance and can be updated wirelessly. As it is mounted to the crank arms 4-arm spider, you can change the chainrings without having to worry about affecting the power measurement. Lighter and stiffer Although the crank arms and spider arms are noticeably bigger to increase stiffness, the overall weight has dropped by 7g over the previous edition of Dura-Ace. The chainset has been adapted to work with disc brake road bikes that generally have 135mm rear hub spacing and shorter chainstays without the need to increase Q-factor thanks to its wider chainring spacing. This Compact version features a 50/34T chainring profile to offer an excellent rider tuned gear combination for varied conditions from flats to high mountains.
These Shimano Saint M820 cranks have evolved to increase rigidity, reduce weight, and improve strength. Saint HollowTech II integrated bottom bracket design uses a wide bearing placement and a large axle diameter for increased stiffness and efficiency combined with longer bearing cup threads for added durability. Saint M820 series crank sets are Dyna Sys 10-speed compatible giving the rider more gear combinations whilst maintaining low weight. Reinforced pedal and crank arm interface with T-nut style steel threaded bushing while the crank arm profile gives excellent ankle clearance also increasing rock clearance by removing unneeded material from the end of the crank arm. Gravity riding has progressed with bikes being lighter and trails getting faster. Saint has evolved with this providing a stiff, strong and durable HollowTech II crank set reinforced in all the ways that most extreme chainsets are not.

The HollowTech II Chainset features hollow forged crank arms which are both lightweight and rigid whilst being incredibly strong and durable. HollowTech II integrated bottom bracket design uses a wide bearing placement with a large axle diameter for increased stiffness, efficiency and added durability. HG-X chainring with patented spike pins give smooth and fast gear shifts under load. With a 48.8mm double ring chain line for use in conjunction with 135 / 142 mm O.L.D. We recommend that the bottom bracket is initially installed by a bike shop to ensure perfect facing and fit.
Available in two cassette ratios, the 11-25T is ideal for racing whilst the 12-2T8 is more suited to hill climbing sessions, such as sportives or endurance events.

The Hyperglide (HG) sprockets on the Shimano SLX 11 speed cassette have a computer designed tooth configuration with contoured shift gates, resulting in a crisp smooth shift even under load. Close ratio gearing allows more efficient use of energy through finer cadence control. Also, the sprockets are cut away and drilled to reduce weight without reducing rigidity.
The Dyna-Sys technology on the Shimano XT M771 cassette provides more efficient power transfer. The power of the rider is transferred more efficiently due to reduced chain tension, less need to change gear and improved continuous cadence due to a closer chainring combination on the chainset and wider cassette ratios. These points improve pedalling efficiency, give smoother and more comfortable front shifting while having less effect on pedal feedback when used on suspension bikes. Cassette Ratios: Option 1 Sprocket Sizes: 11-13-15-17-19-21-24-28-32-36T Option 2 Sprocket Sizes:11-13-15-17-19-21-23-26-30-34T Option 3 Sprocket Sizes: 11-12-14-16-18-20-22-25-28-32T
The close-ratio gearing of the Shimano HG50 8 speed cassette allows more efficient use of energy through finer cadence control. The sprockets are cut away to further reduce weight without reducing rigidity and the Nickel-plated finish offers hard wearing resistance to corrosion.
This Shimano Deore XT M8000 double chainset offers an unrivalled strength-to-weight ratio and is the perfect companion for your 11 speed drivetrain. Durable and Rigid Crankset This Shimano XT M8000 Single 11-Speed Crankset features a new 3D composite tooth composition, which is optimised to support the load that is attributed to the chainring with enhanced chain retention.
