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 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.
Although the crank arms and spider arms are noticeably bigger, which increases stiffness, the overall weight has dropped by 7g over the previous edition of Dura-Ace. The crankset 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. The Compact version offered here features a 50.34T chainring profile to offer an excellent rider tuned gear combination for varied conditions from flats to high mountains. Please note: Bottom bracket is NOT included.
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 HollowTech II Chainset features hollow forged crank arms which are both lightweight and rigid whilst being incredibly strong and durable.

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.
These Shimano Saint M820 cranks have evolved to increase rigidity, reduce weight, and improve strength.
