Shimano Focuses on Triple with Dyna-Sys Compact
For more than 30 years, 26-inch wheels were standard for MTB. All components were optimized for this size. However the success of the 29-er in Europe changed the market and Shimano is adjusting its strategy
The breakthrough of the 29-er in the USA and Europe, together with the promising market response to the 27.5-inch (650b) wheels made Shimano decide to develop a crankset dedicated for these large wheel size bikes. The Dyna-Sys compact triple crankset as it is called, features a 40-30-22 T.
New front derailleur
With the new Dyna-Sys drive, Shimano offers versatility to benefit every type of rider. Suitable for any terrain and any kind of bike, Dyna-Sys features a wide range with large transmission ratios. The Dyna-Sys compact triple cranks are on the Deore XT quality level, with a balance of strength, rigidity, and light weight, and Shimano’s Hollowtech II technology.
To be able to switch to the Dyna-Sys compact triple crankset Shimano developed a new front derailleur. It has the same light action, which can be switched smoothly, and a low profile, such as the current front derailleurs, but with the compatibility of the original and the new 40-30-22 T and 42-32-24 T combination.
All new Deore
Four years after its last introduction, Shimano has developed a completely new Deore mountain bike groupset. Deore is designed to fit various bikes, whether it is for a cross country, or a trail ride on a hard tail, big wheel or full suspension bike. The new Deore has more gearing options and adopted technologies from other Shimano grouppos.
From XT for example, the new Deore benefits from increased braking power, control, and Shimano’s new Dyna-Sys compact triple crankset. The drivetrain is improved, with a full line up of new specifications combining technologies from XT and SLX, such as the Shadow RD+ for more control and a silent drivetrain , plus the RD direct mount for more stiffness and stability. Deore is available in several new gearing options including a double crankset version.
The new Deore is compatible with Shimano’s Ice Technology rotors and brake pads and features a short stroke Servo Wave mechanism and a 2-finger ergonomic brake lever.
