Shimano has announced what it describes as a 'completely new drivetrain technology for mountain bikes' - the ten speed Dyna-Sys.
Shimano introduces a wide range of 3x10 mountain bike components with Dyna-Sys drivetrain. Available this spring will be the new Deore XT and SLX groups, as well as a Dyna-Sys non-series crankset FC-M552 in black and silver.
These products are an addition to the nine-speed components; they can easily be recognized by the Dyna-Sys logo. Visually, the components are identical to the nine-speed versions. Technically, they offer the new state-of-the-art in component technology: Dyna-Sys.
Advantages of this new system include a seamless shift which enables the rider to easily maintain a steady cadence through changes.
Traditionally, riders have had to get used to making two or three recovery shifts in the rear every time they drop into the 22T granny. With Dyna-Sys, it’s just one recovery shift and it’s needed less often.
