TECHNOLOGIES

Hyperglide+ is the efficient further development of the Hyperglide system by Shimano. These are shifting aids and specially shaped sprocket teeth that make shifting to larger or smaller sprockets suppler, smoother and quieter. The system of small rivets and ramps machined or pressed into the side of the sprocket ensures that the chain is taken along by the next sprocket before it leaves the previous sprocket. Hyperglide+ is optimised for faster shifting and shifting under load and, in combination with an HG+ chain, has more efficient chain connection, retention force and power transmission. Compared to Hyperglide, the shifting time is reduced by one third and the pedal stroke is noticeably reduced. It enables a completely new chain stability and thus offers a safe riding experience.
