A Seven Cycles 622 SLX road bike (www.sevencycles.com). I’m an avid cyclist. This bike is new for the 2012 model year for Seven and it is their lightest production frame to date. Each Seven bicycle is custom made in Watertown for the rider’s specific body type and riding style. It’s a beautiful marriage of carbon and titanium. Or an Evoluzione Range espresso machine from Rocket Espresso is the Ferrari of espresso machines and would be a perfect addition to my home kitchen.
If you’ve ever been over your handlebars into a sand pit, you know that the forces that come to bear on a cyclocross bike can be both unexpected and catastrophic. You also know that trying to get all that sand out of your mouth is much more complicated than simply swishing some post-race beer around and then spitting, like you were at the outdoor dentist.
Because of the big hits a typical CX race bike takes, we think that a pure carbon frame is the wrong tool for the job. There simply isn’t enough forgiveness in that material to justify the weight savings you would get over a metal bike. That doesn’t mean carbon fiber has no place on the course though.
Carbon fiber is good at two things. First, it eats high-frequency vibration better than metal, so having some carbon in your CX frame is good when you’re flying over grass or even grinding a big gear on a paved section. You’ll be smoother and get better power transfer. The other thing carbon fiber is good at is being light. Light can be good when you’re racing, right?
But it’s not everything.
Metal is good at some things, too. Titanium, for example, will give a frame a suppleness and a maneuverability that an all-carbon fiber frame doesn’t have. In the technical section of any course, in the switchbacks or in the mud, titanium will give you the ability to use your whole body to steer with. A titanium drive train will be easier to power in chattery sections than a carbon one. Sometimes a little flex is a good thing.
At Seven, we have the ability to build an all-carbon cyclocross racer and make it every bit as customizable as any of the other bikes we build. When we set out to expand our cross line though, an all-carbon bike never even crossed our minds.Instead we built the machine that would come to be known as the Mudhoney PRO.
The 2012 Mudhoney PRO
The Mudhoney PRO aspires to wring every last advantage out of the two materials in its design. The carbon fiber top, seat, head, and down tubes form a light triangle. Matching seat stays settle your saddle. By putting titanium lugs and chainstays into the mix, we getsuppleness where we want it, plus added durability. A titanium drive train will improve tracking and traction; it will hold the ground better than a carbon one, especially in the more technical sections.
Marrying materials in this way isn’t easy; it takes advanced bonding techniques to gain all these advantages and still be able to offer a lifetime warranty. Luckily, we’ve been mixing titanium and carbonsince 1997.
We can’t guarantee you won’t go over the bars of the Mudhoney PRO. When it comes right down to it, sand is unpredictable, and we could all use more practice carrying momentum from the fast parts of the course into the technical sections. What we will say is that you won’t find a cross racer that trackstruer and holds the ground better. And there’s always that post race beer to look forward to.
Made in Massachusetts, USA, the Seven Elium SLX incorporates a carbon fibre toptube, seat-tube and seatstays into a titanium frame. The idea is to combine the ride qualities of each material to create a light, responsive and supremely comfortable frame. This bike, built in Lottery-win spec with Dura-Ace Di2 and Lightweigth wheels, weigths 6.86kg without pedals yet is rated for riders up to 110kg. Options include a longer headtube, pump peg, single and fixed gear, Di2-specific cable-routing and custom colours.
We talk about customization a lot, but the word itself means so many different things to so many different people it becomes sort of meaningless, another bike industry buzz word that flies around but seldom lands. We thought it might be a good idea to explain howWE customize a bike using the Bicycling magazine test bike we built for Joe Lindsey as an example.
The truth is we didn’t want to send Joe an Axiom SL, initially. When he got in touch with us we were just putting the finishing touches on the 622 SLX, and the opportunity to put our newest creation into a big magazine was exciting.
But Joe didn’t want a purpose-built speed demon. He was more interested in versatility and timelessness, so we arrived, together,at the Axiom SL. It’s light, but not the lightest. It can race, or it can tour. And it showcases our double-butting process, one of the ways we tune ride characteristics to the rider.
Joe filled out our Custom Kit, a small pamphlet we developed to capture all the ideas a rider has about his or her new bike, and also to learn some things the rider might not mention otherwise. It starts with personal information, name, age, and weight, but also occupation and geographic location. We ask about what people do, so that we can get a sense for their everyday ergonomics. Do they sit at a desk all day or are they more active? Clues like this tell us a lot about how a rider will approach their new bike. Where they live gives us some idea about the roads they’ll ride, the hills or the flats, the quality of the surfaces.
Since opening in 1997, Massachusetts-based Seven Cycles has produced everything from belt-drive commuters to carbon-fiber time-trial bikes. But Seven’s beating heart has always been custom titanium, a legacy of founder Rob Vandermark’s long tenure at one-time industry leader Merlin Metalworks. When he left, he took his vision and expertise (not to mention several employees). If you want a Merlin today, you buy a Seven. The Axiom SL, Seven’s most traditional and versatile frame, is a study in the company’s philosophy: Fit and ride quality are paramount, while character and performance are almost infinitely malleable. A dream bike is not just a machine: it’s a deeply personal expression of a rider’s self, entrusted to master craftsmen to interpret and make real. We do not choose lightly whom to entrust with those dreams; with our test Axiom SL, as with thousands of frames before it, Seven has earned that trust.
The Axiom is not going to be mistaken for a top-drawer carbon race bike. It flexes, but in doing so shows it’s alive. Seven can tune even more stiffness into the bike, but I wanted a more balanced ride. This bike proves that you don’t need carbon for performance. Like other custom shops, Seven can build in a BB30 bottom bracket, but this bike is wonderfully reverent, with a traditional 68mm BB shell and a straight 1 1/8-inch steerer tube with a standard King headset. Though the bike isn’t the lightest, at 16.04 pounds for a 54cm, it climbs as well as, or better than, bikes that weight much less.
This Axiom uses a very neat Di2 setup, with just three holes in the frame—near the head tube for the wiring harness, and at the seat tube and chainstay for each of the derailleur wires. The battery is housed in the seat post, which gives the bike a clean and stealthy look. Should you ever decide to go back to mechanical, you could get cable stops on the frame even after the fact.
