I may get pleasure from reviving bicycles with non-indexed bar-ends and six-speed freewheels, but I understand, even if I don’t exactly cherish, the allure of “what’s next.” Bicycle Retailer recently reported the interest of Kickstarter followers in new bike technology this way: “Kettle Cycles wanted to raise $15,000 on Kickstarter to produce its new ceramic disc brake rotor. The company brought in over $70,000.” Interested? Follow your money to more information on this Spring Grove, Illinois, company and its 40-gram wonder. (Kickstarter)
The past twenty years have seen little change in the basic frame-tubing silhouette of tandem bicycles. Most of the bikes I see are direct laterals (which include a “stiffening” tube that extends from the head tube at the front of the bike to the rear bottom bracket); though I also see open frames (no frame tube crossing another tube). But I’ve never seen anything like this early Peugeot “ladyback.” I didn’t even remember Peugeot once made tandems, though this site guesses that more Peugeots were sold in the 1970s and 80s than any other make.

Today, there are two basic ways to attach a wheel to a bicycle: 1) nuts and/or bolts, and 2) quick releases. The former requires a tool, the latter just a hand. But there used to be a third option: the wingnut, basically a nut with two levers (the wing). No wrench required. Just turn it by hand (and hope you get it tight enough). You need to know about this bit of retrotech before you understand how utterly nifty this variation is. Ladies and gentlemen: I present the locking wingnut. (Bikeville Thoughts)
Everything old is new again. You call it a camping bike; I call it well equipped. (Lovely Bicycle)
Given enough time and money, I would buy just about anything—just to experience it. One of my long-term ambitions includes wheels with wooden rims. However, if for no other reason than to prove I retain a certain amount of technological prejudice, I think I’ll leave the wooden helmet on the shelf. (Sacro Bosco Bicycle Works)
