DESCRIPTION

When you want the latest in drivetrain technology, look to Shimano and its new XT Dyna-Sys FC-M770-10 Triple Crankset. Shimano reinforces the center, long-wearing steel ring with carbon fiber composite so shifts are precisei.e. minimal flexwhile the inner and outer chainrings are machined out of alloy to reduce as much weight as possible. While Shimano does ditch as much material as possible to reduce weight, it also machines ramps into the rings to enhance shifting by guiding the chain. Sharing
