Shimano Nexus

The series is primarily aimed at the "comfort" market such as urban commuters and tourers, and as such is not made to withstand the rigours of off-road or mountain biking.

In 1995, Shimano rolled out its Nexus line of seven- and four-speed internal hubs.

These had a new rotary actuator that did away with externally protruding gear shifting elements in the rear wheel.

In the early 2000s the 8-speed Nexus hub gear was introduced, having two stepped planetary series mounted downstream of each other.

It weighs 1220 grams stripped in its basic version (without built-in brake).

[11] Shimano claims improvements in shifting under torque and rotation durability over the C6000-series Nexus 8 hubs.

Inter 8 - The Inter 8 has interval percentages between the gears of 22, 16, 14, 18, 22, 16, 14, and a total range of 307%, comparable to a road bike derailleur gear systems, but as the other Nexus products, it is designed and intended for urban commuter use.
