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

Seven featured on Bicycling.com

Seven Cafe Racer

One of the things a custom builder can do better than most production builders is find the sweet spots in between the traditional cycling categories. Constance Winters of Bicycling.com recently tested our Cafe Racer SL in just such a special configuration, somewhere in the space between go-fast road bike and all-purpose commuter.

First, this bike has S&S couplings so it can be broken down for travel. Total time to assemble this one, straight out of the case, is about ten minutes.

Next, it has a custom Tiberius handlebar, which gives the rider multiple hand position options, both aggressive and more upright.

And finally, it features a super quiet, super clean single-speed belt drive. The belt keeps you from getting grease on your pants if you’re riding for business, and its elegant simplicity makes break down and reassembly that much easier.

All of this in a sub-15lb package.

Stripped Down

Niel's new Seven singlespeed mountain bike

You would never design a whole bike build around a handlebar, except for those rare instances where someone hands you a Ti riser bar and leaves you to think about what its best use might be. This is another one of Neil’s projects, and the bar in question wasn’t so much the inspiration for the build, but rather the final piece of a puzzle that had been assembling itself somewhere in the dark recesses of his brain for some time.

He had the frame, acquired at a Seven employee auction a few years back. It had a short life as his every day mountain bike, but he found the geometry left him more upright than he liked to be over root and rock here in our New England woods, so it was in his “parts bin.”

Neil’s parts bin is like most people’s garage, just to paint you a picture.

There was also a Forward Components Eccentric Bottom Bracket, an external solution to retrofitting a single-speed drive train from a company that is no longer. These are the sorts of things Neil collects, and of course, because we have a wide assortment of lathes and mills, he and Mike were able to machine the arms of a Deore crank to work with the EBB in this configuration.

Add in a set of Avid mechanical disc brakes and a pair of Schwalbe Big Apple tires, and you have a balloon-tired, throw-back BMX, an over-sized version of the bike many of us cut our dirt-jumping teeth on.

Now this bike lives in our indoor parking lot, and it gets taken out for lunch on the regular. And just like those bikes we all grew up on, it loves to jump curb cuts and bunny hop flower beds on its way to picking up delicious sandwiches or just practicing wheelies in the parking lot.

Neast Magazine: The Ultimate singlespeed?

Singlespeed Mountain Bikes are Taking the Sport Back to It’s Coreby Mark RiedySeven mountain bike

The singlespeed phenomenon has created a new market for purpose-built bikes and components. Now that many bike companies have added singlespeeds to their product lines, riding with one gear no longer means converting clunky, heavy beater bikes with parts pulled from the scrap pile. Based on traditional mountain-bike frames, singlespeeds use either vertical track dropouts or elliptical tandem bottom-bracket shells to allow for perfectly adjusted chain tension. But while the gearing is simple, the rest of a singlespeed can be as cutting edge as any geared bike out there.

Seven Cycles, a leading builder of titanium and steel frames based in Watertown, Massachusetts, offers a full line of singlespeed options to suit budgets large and small. Seven’s Sola 29’er boasts cutting-edge titanium tubing built around a 29-inch wheeled platform; with the bigger wheels allowing for better climbing and smoother descending. Bontrager’s carbon-fiber bars and seatpost provide incredible strength and durability at feathery low weights, while the White Brothers air/oil fork dishes out four inches of plush travel. Avid Juicy hydraulic disc brakes show everything down in short order and TruVativ’s beefy singlespeed cranks get you going again. At a hair under 20 pounds, the Sola is not cheap, but if you’re serious about the one-gear revolution it surely a worthwhile purchase. Get crankin’.

Singlespeed Mountain Bikes are Taking the Sport Back to It’s Coreby Chris MillmanSeven icon

The new revolution in mountain biking is, in fact, de-evolution. The beauty and simplicity of tackling trails with only one gear is finding a wider acceptance among the knobby-tired set, with singlespeeders getting their own categories in races and, in some cases, winning non-singlespeed events outright.

“I’ve seen singlespeed racing doubling every year for the past four or five years,” says Laird Knight of Granny Gear Productions, organizers of 24-hour mountain bike events.

When veteran mountain bike pro Travis Brown talks about racing, he reserves the most reverential words for his most paired-down biking experience. Brown won the inaugural Single Speed World Championships in 1999, and then again in 2002, and has the obligatory race-winner’s tattoo to prove it.

“It’s difficult to explain without sounding silly,” says Brown of the singlespeed experience, “but I see the way it’s growing and catching on, so I know that people who try riding one understand what it’s all about.”

Racers like Brown are finding freedom and purity by stripping down the drivetrain to its essentials. But just because the bikes are losing derailleurs and shifters, doesn’t mean they’re resolutely low-tech. While many of the original singlespeeds were leftover bikes decked out with leftover parts, today’s singlespeeds tickle the lower reaches of weight and upper heights of performance, utilizing titanium frames, hydraulic disk brakes, carbon handlebars and long-travel suspension forks. Singlespeeders make it over the steepest climbs with a sheer force of will, and the improved energy transfer of a perfectly aligned drivetrain.

“Once I started riding one, I had a revelation about the simplicity of the ride,” says Brown. “It’s quiet, light and smooth. To me it distills the riding experience.”
