They do so on equipment most of us wouldn’t touch and under the most adverse conditions: at the height of rush hour on the busiest thoroughfares. Neighborhood after neighborhood revealed surprise after surprise. The Invisible Riders, for instance, log far more hours than most “serious” cyclists. Koeppel certainly thought it would surprise the readers of Bicycling magazine: Writer Dan Koeppel spent several weeks riding with and getting to know these 'invisible cyclists' in the Los Angeles area and turned up a lot of information that may surprise the Americans who publicly identify as cyclists. Trek’s lightweight, ultra-strong Alpha Aluminum frames with Invisible Weld Technology disrupt the notion that an aluminum bike can’t compete in ride quality or weight with a carbon bike.An article in Bicycling magazine called, 'How Low-Income Cyclists Go Unnoticed' offers an important look at an 'invisible' segment of the biking population: The low-income people who use their bikes to get to work, not to save a little money or for the purposes of exercise, but because they have no other option. Using less weld material also allows production engineers to control every gram of material that goes into the bike, which results in frames that are lighter than many carbon fiber alternatives. Less weld material allows for larger continuous surface areas on the frame, which increases strength and durability. By forming pressurized tube shapes that fit together perfectly, Trek’s engineers make it easier not only to weld tubes into frames, but dramatically reduce the amount of weld material required to do so. Invisible Weld Technology produces welds that are just that-invisible. A premium road bike requires clean, esteemed aesthetics that are not blemished by sloppy, highly visible weld material at every joint. Trek’s advanced Alpha Aluminum frames feature Invisible Weld Technology, a revolutionary welding process that decreases weight and increases structural integrity, while also delivering finely tuned welds that are as aesthetically pleasing as they are strong. More than ever, an aluminum bike is the only bike you’ll need for recreation, touring, training, and competition. The result is a more enjoyable ride that expands the opportunities for you to comfortably enjoy your aluminum frame.With Alpha Aluminum you won’t have to think twice about hitting the gravel or signing up for a multiple-day tour. By taking a comprehensive approach to frame design and construction, Trek is able to fine-tune frames to be stiff where necessary and compliant where possible. Unfortunately, what starts out as a snappy, fun ride can quickly become uncomfortable and fatiguing on long or rough outings, making aluminum a poor choice for endurance and adventure-minded riders.Alpha Aluminum was developed to build more compliant frames that retain the acceleration and affordability that have always made aluminum popular.

The engineers at Trek have made it their mission to challenge this assumption, using methods that allow the material to retain its best characteristics-its lightness and strength-while simultaneously improving ride quality.Many cyclists enjoy the responsiveness that comes with stiffer aluminum frames. Over the years, aluminum frames have earned a reputation as being overly stiff and providing poor ride quality compared to their carbon brethren.
