U.S. Built Custom Bicycles in Titanium and Titanium-Carbon Mix

Mountain Flyer Magazine: Seven Cycles IMX – Artistic License to Rip

One look at the Seven Cycles IMX and you know this isn’t your standard mountain bike. Sleek titanium melds into carbon fiber graced by an artistic weave. If you’re thinking this is more art than bike, you’re only partially right.

Like all good artists, Seven Cycles backs up its artistry with well thought-out design and understanding of the medium, all combined for one ultimate goal. In this case, of course, the main objective is that bike you’ve always dreamed of.

Using a blend of titanium and carbon fiber tubes is not new for Seven. The company has used carbon fiber for its top tubes and seat tubes for some road bike models since 1997. A carbon fiber top tube adds a measure of stiffness to the titanium to translate any motion forward and give it quicker handling. Added to the seat tube, carbon fiber boosts the compliance characteristics of the titanium in the vertical plane; that’s more rear-end comfort to you and me.

Seven realized that using a ti/carbon tube combo in mountain bikes would impart two main benefits to the bike. First, lighter carbon fiber would drop the frame weight. In fact, the IMX weighs 10 percent less than the company’s top selling all-ti Sola mountain bike. And second, keeping titanium in the places most vulnerable to frame-seeking rock missiles makes the bike more impact resistant. That’s peace of mind for hammerheads pounding down a loose, rocky trail.

IMX Top Tube
Seven opts for a filament-wound carbon fiber instead of carbon fiber molding for its top tube in the IMX. The natural weave creates a striking pattern on the tubes.

The next question is how it rides—a bit that depends entirely on you, and I don’t mean your riding style. Except for stock sized in its Signature Size program, Seven relies almost entirely on custom builds. There is no standard inseam, arm-length, or quick bike fit custom program, although it is relatively quick. Seven has a 12-page Custom Kit explaining its custom program and asking you 100 questions, covering not only your body measurements, but also how you ride, what you ride (and all those measurements), where you ride and what hurts and feels good when you ride.

IMX Welds
You can’t beat beautiful welds like this in titanium. The IMX uses butted titanium tubes for its frame junctions.

Your own riding preferences funnel directly into Seven’s frame design for you. For example, a stiff drive train maximizes power transfer from your legs to the rear wheel, perfect for someone wanting instant speed. But a less stiff drive train gives you a lighter frame weight. Which do you prefer? I think you know. After you finish the Custom Kit with your local retailer (in addition to choosing components, frame accessories cable routing options and paint color design), Seven’s designers then work out the frame angles, tube sizes, thickness and lengths to fit your preferences. All told, the process of working with your retailer on the Custom Kit and with Seven up to the final frame design takes 12 days. Production time is typically two to four weeks.

Road Bike Action Magazine: Industry Insight – Rob Vandermark defines Custom

Rob Vandermark is the founder of Seven Cycles and over the last decade he has been dedicated to creating and perfecting the ultimate custom-bike build program. With the recent proliferation of custom builders, we decided to ask his opinion on where the custom bike business is these days:

“This is an area that is in upheaval at the moment. Over the next decade the effect of customization, improved fitting technologies, an aging population and ever-increasing customer expectations will coalesce. The result will be a technology-driven market for improved individualization, bike fit, and performance for the high-end customer. However; in response, the industry is bifurcating at the moment. On the one hand ‘custom’ is all the rage, and nearly every high-end bicycle retailer is providing fitting services. On the other hand, more and more bike suppliers are offering fewer and fewer sizes of bike. In the next decade, customization, individualization, and tailor-ablity will play a larger role in frame and component design and compatibility.”

Frames

“True customization will be the cost of entry for smaller builders. Customization will not look like what most people think of today; customization will encompass a lot more than just the fit of the bike. More companies will embrace the challenge of customizing for improved performance, comfort, service life, and planning for the future use of the bike.”

“Custom frames will be customized not just in terms of frame geometry—each tube angle, top tube, etc.—but also in terms of ride characteristics through tailoring each tube of the bike and the actual geometry of the frame to accentuate or mitigate characteristics of performance and material.”

Components

“Components obviously have a big impact on the fit and performance of a bike. From a fit standpoint, components will play a larger role in the optimization of bike fit—components that are more adjustable in size than current offerings. These parts will be adjustable for rider size, changing use—road training during the week versus road racing on weekends for example—and for evolving fitness and skill.”

Materials

“Materials will be applied more specifically to the customization process. Material choice currently is driven by perceived technological value—or, at least, perceived ‘cutting edge’ value. Soon, particularly as carbon’s strengths and weaknesses become better understood in the market, the four primary materials—as well as the newer ones on the way—will be applied, not so much for wow factor but rather because they are the right materials for rider’s needs.”
