I made these to illustrate the difference between shifting a Rohloff vs. conventional derailleur/cassette system in a velomobile going at speed. According to Doug Davis at Bicycle Evolution, some novice velonauts desire Rohloffs because they offer a very wide gear range, but the larger gaps between gears make them less efficient at speed. He has data about watts and gear inches and rotations per minute, but I merely tried to convey the drama of having to upshift too fast in a 60+ pound tub:
For contrast, the illustration below represents a more narrowly spaced conventional rear cassette setup, like what I have on my Mango:
Maybe we’ll talk about this, and other recumbent nerd stuff, on the next Laidback Bike Report.
14 hours before Winter Solstice, my friend Mike Barkley took these photos of me in the Dress-That-Looks-Like-A-Tree, next to the Tree that looks like the Dress-That-Looks-Like-A-Tree, in the woods at Allerton Park. It was pretty freaking cold, just barely 40°F, and I had pedaled my velomobile 30 miles there in a headwind. We suffered for Art/Fashion!
Animating waves does not come naturally to me. I covet the skills of animators who do them well, so when I recently found myself staring at the animated gifs of Felix Colgrave, I thought, “I wish I could do that.” Then I thought – hey, maybe I can. Thus, using repeating waves as guidelines:
I made this:
It may not look like much to you, but for me, it is an achievement, promising more interesting possibilities to come.
Not a Hundred Dollar Drawing, but close enough.
