Shadow + uses a clutch to lessen tension - otherwise getting a wheel in or out would be close to impossible.

Shadow + puts the most tension on the derailleur of any shift system, meaning less chain drops and no chain slap. Shimano's Deore series has been on the market for more than 30 years and has been constantly optimized and enhanced. It features impressive, tried-and-tested technology and is extremely reliable, well-engineered and easy to use. Shimano Deore gears have proven their worth for many decades and are indispensable premium components even in the E-Bike sector. Shimano Shadow + is featured on Deore touring and mountain models equipped with 10-speed or 11-speed Shimano Deore or Deore XT gears, depending on the model.

A well-maintained derailleur gear has the best degree of efficiency of all the possible types of transmission. This is important for sporty riders who want to eke every last metre of range from their E-Bikes. Derailleur gears come in the classic design with cables and manual gear levers as well as in electronic versions. In this case a cable runs through the frame instead of a gear cable. Lightly tapping the buttons on the handlebar quickly and accurately switches to the desired gear.
