The Inter 5E shares its hub shell with the Nexus 8, distinguishing itself from the earlier Inter 5.

A forum discussion contains a link to one of two parts lists at Shimano. Inter 5 - Apparently in 2012 Shimano has started making Nexus Inter 5 hubs. It has been discontinued and spare parts have become hard to source. It only geared up, so a relatively large rear sprocket was necessary to give a reasonable development when combined with a normal front sprocket. Inter 4 - Nexus Inter 4 hubs had four speeds, but the same 186% range as the Inter 3. A similar system was built for the nexus 4. Starting from around 2011 Shimano offers a model with a rotary shifting mechanism similar to the one originally developed for the Inter 7 instead of the push rod/bell crank mechanism.Īuto 3 - The hub is fitted with a 3 speed automatic gear system, which utilizes a front hub dynamo to power a CPU that automatically changes the three speed internally geared hub.

Also, the gear units were able to be shifted under moderate pedaling loads. These had a new rotary actuator that did away with externally protruding gear shifting elements in the rear wheel. In 1995, Shimano rolled out its Nexus line of seven- and four-speed internal hubs. The free-wheeling Nexus internal gear hubs are compatible with Shimano's "roller brake", its version of a drum brake, but not with the Shimano disc brakes used with the higher-end Shimano Alfine internal gear hubs. 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. Shimano Nexus is a brand of bicycle components which includes products such as epicyclical gear hubs, cranksets, shifters, brake levers, hub brakes, hub dynamos, and a CPU for automatically changing gears. ![]() Shimano Nexus Inter 8 hub excluding auxiliary components.
