Rhythm and Range  The real advantage of 11-speed is the ability to have all the range you require without sacrificing the rhythm you need.

Wider Driving Range / Total Range Gear Range Comparison

DYNA-SYS11

RANGE Optimized Chainwheels

Chainwheels matched with specific sprockets for:

  • Improved gear quality and driving efficiency

    - Reduced cross-chain

    - Effective gear steps

  • Larger diameter, longer wearing cogs

At the range

DRIVING: gears are purpose matched to keep you riding efficiently without front shifting

CLIMBING: gears are chosen to compliment the lowest cogs and maximize seated traction

Driving range

DYNA-SYS11 maximizes rhythm with “rhythm step” gears in the most frequently used range.

  • Less front shifting thanks to optimum front gear teeth
  • Rider controls cadence and energy use by rear close ratio

Climbing range

DYNA-SYS11 maximizes rhythm with “rhythm step” gears in the most frequently used range.

  • Smooth shifting performance thanks to front close gear ratio
  • Rider controls cadence and energy use by rear close ratio

Highly Efficient gear combination

Driving efficiency is a key drivetrain performance indicator.

  • More speed for the same effort
  • Multiple front gear (2x, 3x) maintains higher efficiency in all range

hg_hyperglide

Hyperglide

The distinctively designed HYPERGLIDE sprockets incorporate specially positioned shift ramps and tooth profiles for improved chain control during shifting. Fast and responsive indexed shifting is the result. 
The HG cassette sprocket, which was developed for the MTB 10-speed system, underwent comprehensive optimization to achieve super-highly efficient shifting.

Conventional sprockets

Cause the chain to ride up and over the gear teeth before engaging the sprocket.

    Expensive and works great!

    11 speed (11-13-15-17-19-21-24-28-32-37-42). Though slightly heavier than the 11-32 cassette, the 42T gives me a bail-out cog and more importantly -- a better chain line when wuzzing uphill in the 32T. The lockring is aluminium (less weight, more care). Shifts well.
    I'm using the cassette with a KMC chain, 32T Praxis front chain ring and an mtb rear mech (both XTR RD-9000 medium cage and the XT M8000 medium cage work). To get the transmission to work on a road bike (which has shorter chainstays than a mountain bike), I had to play around with chain length and the 'B' tension screw a bit, but it works well. Tip - Fevibond (not Fevikwik) the adjustment screws to prevent them loosening or falling off. WD40 loosens the glue when one needs to adjust the derailleur.
