cyclingweekly.co Frame builder, mountain bike pioneer, component, wheel and tyre designer, consultant with Trek Bicycle and a hell of a cook, Keith Bontrager has been at the pointy end of the bike industry for over 30 years. A former motocross racer who also tuned engines, Bontrager started building road frames in the late 1970s. He then made some of the earliest mountain bike frames before he sold his company to Trek in 1995, who also hired him as a parts designer and consultant. But Bontrager, now an absurdly youthful looking 59-year-old with a range of experience that is unique in the bike industry, actually started out as a physicist, gaining a degree in the subject from the University of Santa Cruz. “You can look at things, at explanations and say, ‘No, that’s not right.’

BikeHacks Reader Matteo recently contacted us and noted that he had turned an old wheel into a ceiling light. His bike deco hack kicked my brain into search mode for another post along the same lines, and before I knew it was in full search mode for hacks we have posted related to decorations made from bike parts. A bunch of time typing and mousing through memory lane resulted in this cumulative post. If you have a bike deco hack you would like to have featured on bikehacks.com let us know.

Improving Chain Lubrication The majority of chains used in industry suffer unnecessarily short lives. This leads many companies to forego chains all together and replace them with belts. In most cases, however, the problem is not the fault of the chains but rather the method in which they are lubricated. The current chain lubrication practice consists of applying a heavy oil or grease to the outside of the chain. While this does a nice job of lubricating the sprockets and the outside of the chain, it does little to protect the most vulnerable area of the chain: the contacting surfaces inside the pin and bushing/ plate/ roller/ hook. The majority of chains fail from the inside.

You might ask, “Why are those thickener types so popular?” and “How do I decide which one is best for my application?” This article will provide answers to these and a few other questions.
Chain Maintenance Chain Maintenance A Religious Question Chain maintenance is one of the most controversial aspects of bicycle mechanics. Chain durability is affected by riding style, gear choice, whether the bicycle is ridden in rain or snow, type of soil in the local terrain, type of lubricant, lubrication techniques, and the sizes and condition of the bicycle's sprockets. Because there are so many variables, it has not been possible to do controlled experiments under real-world conditions. As a result, everybody's advice about chain maintenance is based on anecdotal "evidence" and experience. Mountain bike sizing: what size bike do I need?
