The XTR M9100 series of derailleurs brings a new level of drivetrain silence thank to decreased tension in the low gear position and an added bumper on the pulley cage.
With its BEAM SPIDER construction, the new SHIMANO DEORE M6100 12-speed cassette shaves weight while increasing SHIMANO's MTB gearing range another gear.
The strongest system is a chain with no weak links. Eagle chain links have a smooth radius, with no sharp edges or chamfers, which yield a significant reduction in noise, friction and wear.
It might look normal from the outside, but the engineering inside this incredible chain design makes possible a gear range previously found only in 2-chainring drivetrains.
IT'S TIME TO STOP
Stopping and slowing down is equally as important as going fast and accelerating. It is dangerous to descend steep terrain with weak brakes.
