A recent Trike Asylum blog entry entitled Eulogy to the Front Derailleur inspired me to do a little more thorough investigation of SRAM’s challenge to the front derailleur. Steve gathered a couple of pretty funny videos on the topic, it’s worth checking out the link.
Now that I’ve seen belt drive in action on a couple of “city bikes” in town, I can’t seem to let this one go. On an upright bike, belt drive is smooth, reliable, light, and silent. On a recumbent it has the potential to solve what for many is their bane: a long, greasy, noisy, unwieldy chain. This post is my attempt at taking a closer look to see what might be preventing the adoption of belt drive for recumbents and, specifically, ‘bent trikes. I’ll discuss the issues I see, many unique to ‘bents. Then I’ll see if I can figure out what it would take to adapt my current trike to belt drive. Continue reading
It’s a fact that a typical ‘bent needs wider and lower gearing than a typical upright bike. Just how much wider and lower is a subjective, sometimes technical, and oft’ debated topic that can make large chunks of time vanish. I’ll try to keep this brief. I use Gear Inches in the following discussion because it is commonly used in trike specifications and it provides a good way to make relative comparisons between drivetrains. Consult a Gear Inch Calculator to see how Gear Inches translate into speed.
While I love the idea of Internally Geared Hubs, I’ve had my share of difficulties with them over the years.
Recently I took a trip down to Payson, UT to check out internally geared hubs (IGH). This was a pretty crazy trip, 900 miles and around 12 hours of driving for a couple hours with the folks at Utah Trikes. That says a lot about my expectations for the shop and they didn’t disappoint.

I guess anything under the recumbent banner could be considered unconventional but I think I’ll be pushing into particularly rare territory for this build. My goal is a machine that will be equally comfortable on tour or commuting to work; fun to ride, easy to maintain, impervious to weather. Fast, relatively lightweight, simple, at least externally. Here are some of the characteristics I think will get me the closest. Continue reading
