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.’ You can’t always explain precisely what’s happening but it gives you a solid start point and you can refine it from there.

Bicycle Frame Design Using SOLIDWORKS Simulation Tech Blog post presented by Waleed Al-rabeh, Applications Engineer at Hawk Ridge Systems. In this series, I will design a racing road bicycle with the help of SOLIDWORKS. Starting with the geometry, I will move on to the tube shapes and componentry to come up with an engineered speed machine. What’s to come? Part 1: Frame Geometry Optimization – Using 3D Sketches, Weldments, and Static Analysis to optimize the frame geometry Part 2: Tube Shape Optimization 1 – Using Surfacing and Static Analysis to define the shape of the tubes

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. 1. What's The Best Bike For Cycle Commuting? By John Stevenson, Cycling Plus | Tuesday, April 26, 2011 7.00am Your choice of bike for the ride to work will depend on your own tastes and on the distance, terrain and varying surfaces you’ll encounter on the journey. For longer tarmac commutes, experienced riders tend to favour drop-bar bikes of one sort or another for their extra turn of speed. Many people are happy with the more upright position that you get with a flat-bar road bike or mountain bike with slick tyres, though. If your ride takes in some trails or unsurfaced paths, then the fatter, grippier tyres of a mountain bike will help with traction.

True North Cycles » Custom Bicycles Every bike we make is custom – designed with you and built for you. For this reason, it is sometimes difficult to categorize the bicycles we handcraft. Please consider the headings on this page only as suggestions! Touring Bicycles Since you spend a lot of time on your touring bike, it is important the that your frame fits you perfectly. We make bikes across the entire touring range: from light touring bikes with relaxed geometry for day tripping and supported tours to expedition touring bikes with clearance for fenders and endurance tires for months of unsupported travel to the far corners of the world.

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. Paul Dorn's Bike Commuting Tips: Repairs/Maintenance The most common repair you will encounter as a bike commuter will be a flat tire. You can minimize pneumatic distress by buying durable tires. You should also monitor brake wear to make sure they're not rubbing against the sidewalls of your tires.

ShockStop Takes the Bumps Out of Your Cycle Ride Co-Founder Erik deBrun of Redshift Sports is an avid cyclists; this is his team’s second cycling related product and just like their first (the Switch Aero System – previously featured on SolidSmack) personal experiences and issues as cyclists gave birth to the ShockStop. We asked Erik a few questions regarding this project and this is his story. SS – What is ShockStop? Erik – Like many other cyclists we found that often times riding could be pretty uncomfortable – mostly people feel this where they contact the bike: the seat and the handlebars.

Grease Selection: Lithium vs. Lithium Complex According to a recent NLGI Grease Production Survey, approximately 70 percent of the grease sold worldwide is based on either simple lithium soap or lithium complex thickener. 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. First, let us take a historical perspective.
