Just Three for Me! In Praise of the Humble 3-Speed

When I was first shopping for an upright bicycle with an internally geared hub, I made the natural assumption that the more gears on the hub, the better. But to my surprise, over time I changed my mind and developed a strong preference for the simple 3-speed. No more, no less: Three gears feel just right. I have been trying to make sense of why I prefer 3-speed hubs to the seemingly more advantageous 7-speeds and 8-speeds, and have a couple of ideas.

Internally geared hubs allow for a narrower range of gearing in comparison to derailleurs. And the overall range of the hub does not increase in direct proportion to the number of speeds.

For example:
The Shimano Nexus 3-speed hub has a 186% overall gearing range.
The Shimano Nexus 7-speed hub has a 244% overall gearing range.
The Shimano Alfine 8-speed hub has a 306% overall gearing range.

The typical 7 and 8 speed hubs do not give you more than double the gearing range of the 3-speed. They give you more than double the notches to click, while the overall gearing range is only somewhat greater. The more speeds on the hub, the smaller the differences between clicks. This requires changing gears back and forth more frequently, just to stay in the same range as the 3-speed hub would give you with less clicking. This could be why I feel that with a 7 and 8 speed hub, I am always switching gears back and forth unnecessarily.

My choice of transportation bicycles plays a huge role in the usefulness of the hubs as well. In my experience, bicycles that are heavy and put the cyclist in a bolt-upright position are simply not the best choice for trips with prolonged hills, regardless of how many gears are on the hub. If I max out a 3-speed hub going uphill on a heavy upright bike, chances are that I will also max out a 7 or 8 speed hub - in which case there is no real benefit to having those additional gears. If a route is too tough for a 3-speed, then what I prefer is a lighter and more sporty bike, ideally with derailleur gearing. A bigger hub on the same heavy upright bike does not do me much good.

While modern bicycles are commonly available with 7 and 8 speed hubs, for me the simpler 3-speed just seems to be a better solution. Your experience may differ - but before you choose a hub with many gears, try a 3-speed and compare for yourself. You might be as surprised as I was to discover which you prefer.
